State v. Jacques

Supreme Court of Connecticut

Decided August 26, 2025

Supreme Court of Connecticut · decided 2025-08-26

Convicted, after a second trial, of murder in connection with the stabbing death of the victim, the defendant appealed to this court. The defendant was convicted of murder after his first trial, but this court reversed his conviction and remanded the case for a new trial on the ground that certain illegally obtained evidence had been improperly admitted. Prior to the defen- dant's second trial, defense counsel requested a second probable cause hearing, but the trial court denied that request. The trial court also denied the defendant's pretrial motion to exclude the testimony of a jailhouse informant, V, after making a threshold determination that V's purported testimony was reliable. At the defendant's second trial, the trial court permit- ted the state to introduce, as a prior inconsistent statement, the written statement of the defendant's former cellmate, J, which J had given to the police and which recounted certain inculpatory statements of the defendant. J had testified at the defendant's probable cause hearing and at his first trial but later suffered a stroke prior to the defendant's second trial that allegedly resulted in memory loss. Although J testified at the defendant's second trial, the defense claimed that his alleged memory loss rendered him functionally unavailable as a witness at the second trial. On appeal to this court, the defendant challenged the trial court's rulings on the request for a second probable cause hearing and the admission of J's statement to the police and V's testimony. Held: The trial court did not violate the defendant's state constitutional right to a probable cause hearing by declining counsel's request for a second probable cause hearing after this court reversed the defendant's conviction and remanded the case for a second trial. Neither the state constitution nor the statute (§ 54-46a) governing probable cause hearings requires a second probable cause hearing when an appellate This case was originally argued before a panel of this court consisting of Chief Justice Robinson and Justices McDonald, D'Auria, Mullins, Ecker, Alexander and Dannehy.

The trial court did not violate the defendant's federal constitutional right to confrontation by admitting J's written statement to the police, that court having correctly determined that, despite J's alleged memory loss, J was available at the defendant's second trial for purposes of the defendant's right to confrontation. After reviewing federal and Connecticut case law, this court concluded that J was available for cross-examination for purposes of any claimed violation of the defendant's right to confrontation because J appeared at the defen- dant's second trial, took an oath to testify truthfully, testified that he under- stood the oath, and answered all questions asked of him during cross- examination, during which defense counsel had the opportunity to ask J questions about his prior testimony, during the probable cause hearing and the first trial, regarding his written statement to the police. The trial court did not abuse its discretion in admitting J's written statement to the police as a prior inconsistent statement under State v. Whelan (200 Conn. 743) and the corresponding provision (§ 8-5 (1)) of the Connecticut Code of Evidence. J was available as a witness at the defendant's second trial, it was of no consequence that J could not explain the discrepancies between his written statement to the police and his testimony, insofar as a denial of recollection or a claim of memory loss can serve as the basis for a finding of inconsistency, and defense counsel effectively had conceded that a police officer had typed J's statement and that J had signed it, which satisfied the other elements for the admissibility of a prior inconsistent statement under Whelan and § 8-5 (1) of the Code of Evidence. This court declined the defendant's requests to adopt a prophylactic rule under the state constitution, pursuant to which a witness would not be considered available for cross-examination if, due to a valid medical condi- tion, the witness has no memory of the incident at issue or of making an out-of-court statement about the incident, and to exercise its supervisory authority to modify § 8-5 (1) of the Code of Evidence to preclude the admis- sion of a prior inconsistent statement when a witness who made the prior statement has a medical condition that causes total memory loss. The trial court did not abuse its discretion in making a prima facie determina- tion that V's purported testimony was reliable and therefore admissible at the defendant's second trial. The trial court considered the statutory (§§ 54-86o (a) and 54-86p (a)) factors that may be considered when making a prima facie determination that a jailhouse informant's testimony is reliable, and that court reasonably con- cluded that independent evidence corroborated specific details of V's testi- mony, there was no evidence establishing that those details were publicly available or that V had access to them while he was incarcerated, and the circumstances under which V initially provided information about the defendant to the police supported a finding of reliability.

         death of the victim, the defendant appealed to this court. The defendant
         was convicted of murder after his first trial, but this court reversed his
         conviction and remanded the case for a new trial on the ground that certain
         illegally obtained evidence had been improperly admitted. Prior to the defendant’s second trial, defense counsel requested a second probable cause
         hearing, but the trial court denied that request. The trial court also denied
         the defendant’s pretrial motion to exclude the testimony of a jailhouse
         informant, V, after making a threshold determination that V’s purported
         testimony was reliable. At the defendant’s second trial, the trial court permitted the state to introduce, as a prior inconsistent statement, the written
         statement of the defendant’s former cellmate, J, which J had given to the
         police and which recounted certain inculpatory statements of the defendant.
         J had testified at the defendant’s probable cause hearing and at his first
         trial but later suffered a stroke prior to the defendant’s second trial that
         allegedly resulted in memory loss. Although J testified at the defendant’s
         second trial, the defense claimed that his alleged memory loss rendered
         him functionally unavailable as a witness at the second trial. On appeal to

       court reverses a criminal conviction but does not dismiss the charge or
       charges that resulted in that conviction, the fact that a reviewing court
       determines that illegally obtained evidence should have been excluded at
       the defendant’s trial has no impact on the earlier probable cause determination, and the defendant failed to demonstrate a jurisdictional defect that
       would render the first probable cause hearing invalid and entitle him to a
       second one.

       The trial court did not violate the defendant’s federal constitutional right
       to confrontation by admitting J’s written statement to the police, that court
       having correctly determined that, despite J’s alleged memory loss, J was
       available at the defendant’s second trial for purposes of the defendant’s
       right to confrontation.

       After reviewing federal and Connecticut case law, this court concluded that
       J was available for cross-examination for purposes of any claimed violation
       of the defendant’s right to confrontation because J appeared at the defendant’s second trial, took an oath to testify truthfully, testified that he understood the oath, and answered all questions asked of him during cross-examination, during which defense counsel had the opportunity to ask J
       questions about his prior testimony, during the probable cause hearing and
       the first trial, regarding his written statement to the police.

       The trial court did not abuse its discretion in admitting J’s written statement
       to the police as a prior inconsistent statement under State v. Whelan (
200 Conn. 743
) and the corresponding provision (§ 8-5 (1)) of the Connecticut
       Code of Evidence.

       J was available as a witness at the defendant’s second trial, it was of no
       consequence that J could not explain the discrepancies between his written
       statement to the police and his testimony, insofar as a denial of recollection
       or a claim of memory loss can serve as the basis for a finding of inconsistency,
       and defense counsel effectively had conceded that a police officer had typed
       J’s statement and that J had signed it, which satisfied the other elements
       for the admissibility of a prior inconsistent statement under Whelan and
       § 8-5 (1) of the Code of Evidence.

       This court declined the defendant’s requests to adopt a prophylactic rule
       under the state constitution, pursuant to which a witness would not be
       considered available for cross-examination if, due to a valid medical condition, the witness has no memory of the incident at issue or of making an
       out-of-court statement about the incident, and to exercise its supervisory
       authority to modify § 8-5 (1) of the Code of Evidence to preclude the admission of a prior inconsistent statement when a witness who made the prior
       statement has a medical condition that causes total memory loss.

       The trial court did not abuse its discretion in making a prima facie determination that V’s purported testimony was reliable and therefore admissible at
       the defendant’s second trial.

          On the evening of June 14, 2015, Casey Chadwick
       and her boyfriend, Jean Joseph, were at their apartment
       in Norwich. At approximately 9 or 10 p.m., Joseph left
       the apartment and went to the home of Johane Jean
       Baptiste, the mother of Joseph’s son, where he spent the
       night.1 Around 11 p.m. that evening, Chadwick texted
       Joseph to tell him that the defendant was at their apartment. The defendant knew Chadwick and Joseph
       because he occasionally sold marijuana to them, and
       Joseph would also sometimes sell marijuana to the
       defendant.2 Joseph responded to Chadwick and told
       her to ask the defendant to leave. Joseph also called
       the defendant and asked that he leave the apartment.
       The last outgoing message from Chadwick’s cell phone
       was sent on the morning of June 15, 2015, at 12:20 a.m.
          Later that morning, Joseph woke up, brought his son
       to day care, and attended a doctor’s appointment. He
       also called and texted Chadwick multiple times to let
       her know when he would be back at the apartment and
         1
            Joseph would occasionally spend the night at Baptiste’s home so he
       could spend time with his son. Although Joseph did not intend to spend
       the night at Baptiste’s that evening, he fell asleep on the couch with his son
       during his visit. Joseph remained there until the next morning, at which
       time he brought his son to day care and attended a doctor’s appointment.
          2
            Joseph indicated that he met the defendant through Chadwick. Joseph
       testified that Chadwick was friends with the defendant and that ‘‘he would
       stop by the house sometimes and just joke around, you know, and sit for
       like a good half hour, talk with us, and then just leave.’’

         to apologize that he did not make it home the previous
         night. Chadwick did not pick up his calls or answer
         his text messages. Joseph returned to the apartment
         immediately after his doctor’s appointment and found
         the apartment in disarray. Joseph later described the
         apartment as looking like someone had ‘‘ransacked’’ it.
         Chadwick was not present, and the marijuana that she
         and Joseph had purchased the day before,3 as well as
         some narcotics that Joseph had stored in the kitchen,
         was missing.
            Joseph began to panic when he could not find Chadwick. Fearing that their apartment had been raided by
         the police, and Chadwick arrested, Joseph called the
         police department and then the courthouse. Joseph
         learned nothing of Chadwick’s whereabouts from these
         calls. Joseph also called a local bail bondsman to try
         to figure out what was going on, contacted Chadwick’s
         friend to see if she had heard from Chadwick, and went
         to a neighbor’s house to see if he had seen or heard
         anything. Unable to locate Chadwick or get in contact
         with her, Joseph returned to the apartment. Upon a
         further search of the apartment, Joseph discovered
         Chadwick’s body inside of a closet, bloody and lifeless.
         Joseph called 911 to report what he had found, and
         the police and medical personnel were dispatched to
         the apartment.
           Police officers responding to the call observed Chadwick’s body in a seated, slumped over position in the
         closet with large lacerations to her neck area. A police
         officer at the scene testified that he detected a strong
         odor of cleaning supplies and observed a mop and
         bucket in the kitchen. The police did not find Chadwick’s cell phone or any drugs during their search of
         the apartment.
           3
             Joseph testified that he and Chadwick went to Mystic on June 14, 2015,
         where Chadwick purchased approximately four ounces of marijuana from
         her brother’s friend.

                                     State v. Jacques

         An autopsy determined that Chadwick died as a result
       of numerous sharp force injuries to her head and neck
       that caused massive vascular damage and bleeding. She
       suffered four penetrating stab wounds and eleven lateral incised wounds to the head and neck; incised
       wounds to the right ring finger, left upper arm and left
       wrist; and six blunt force trauma injuries to the torso.
       Her right vertebral artery was damaged, and her right
       jugular vein and right carotid artery were ‘‘cut all the
       way through, severed.’’
         The police learned from Joseph that Chadwick had
       texted him the night before to report that the defendant
       was in the apartment with her. Having reason to believe
       that the defendant was an active drug dealer, the police
       used a confidential informant to contact him on that
       same day to arrange a controlled purchase of cocaine.4
       When the arranged transaction was completed, the
       police arrested the defendant on a drug charge. At the
       time of his arrest, the police noticed blood on the defendant’s shoes and cuts on his hands. Maura DeJoseph,
       the deputy chief medical examiner, examined the defendant’s hands pursuant to a search warrant and opined
       that the cuts thereon appeared to be sharp force injuries
       that may have occurred within one or two days of her
       examination. DeJoseph opined that the cuts could have
       been caused by the defendant’s hands slipping off the
       handle of a knife and down over the blade.5
         4
            Police officers testified that the defendant was familiar to them because
       a confidential informant had previously named the defendant as a drug
       dealer in the downtown area of Norwich. An officer testified that they had
       attempted a controlled purchase with the defendant just four days before
       Chadwick’s murder, but the defendant said he did not have drugs at that time.
          5
            Mandi Edwards, a line cook at the Rustic Café in East Lyme, testified
       that the defendant cut his right hand on a broken plate while working at
       the restaurant on June 14, 2015, as a dishwasher. Merzilas Braboy, another
       restaurant employee who was working at the time, testified that the defendant ‘‘had broken a glass and cut his hand open.’’ DeJoseph acknowledged
       that the cuts on the defendant’s hands also could have been caused by a
       broken plate.

         apartment pursuant to a valid search warrant. They
         discovered, among other things, a first aid kit on top
         of an ironing board and a white, rock like substance
         that appeared to be crack cocaine.6 The police later
         obtained the defendant’s pants from the car of a friend
         who had driven him to a laundromat early in the morning on June 15, 2015. The pants recovered by the police
         had blood stains on them.
           Subsequent forensic testing indicated that the blood
         on the defendant’s shoes and pants was consistent with
         Chadwick’s DNA profile. Forensic testing also indicated
         that blood found on Chadwick’s living room floor was
         consistent with the defendant’s DNA profile. Blood
         found on Chadwick’s kitchen wall came from a blood
         mixture that was consistent with her and the defendant’s DNA profiles. The testing eliminated Joseph as
         a contributor to the blood found on the defendant’s
         shoes and in Chadwick’s apartment.
            The state subsequently charged the defendant with
         one count of murder in violation of § 53a-54a (a). The
         defendant was first tried in 2016, and the jury found
         him guilty of murder. See State v. 
Jacques, supra,
332
         Conn. 277
. This court reversed that judgment of conviction and remanded the case for a new trial, concluding
         that the trial court improperly denied the defendant’s
         motion to suppress evidence that the police had
         obtained during a warrantless search of the defendant’s
         apartment.

 293–94.

             After receiving a tip from a confidential informant, the police later conducted a second search of the defendant’s apartment, this time without a
         warrant. State v. 
Jacques, supra,
332 Conn. 275
. Relying on the informant’s
         statements, the officers located a hole in the wall of the defendant’s bathroom, where they found Chadwick’s cell phone and some drugs. In Jacques,
         we held that the trial court improperly denied the defendant’s motion to
         suppress the evidence seized from this illegal search, and, accordingly, we
         remanded the case for a new trial.

                                    State v. Jacques

          On remand, the trial court denied three pretrial
       motions that are relevant to the defendant’s claims on
       appeal. First, the trial court denied the defendant’s
       motion for a second probable cause hearing. Defense
       counsel argued that a second probable cause hearing
       was required because this court’s reversal of the first
       judgment of conviction started the case ‘‘from scratch,’’
       thereby effectively resetting the defendant’s right to
       such a hearing. Second, the trial court denied the defendant’s motion to exclude the testimony of his former
       cellmate, Jenkins, who previously testified that the
       defendant admitted to him that he had killed Chadwick.
       The defendant claimed, among other things, that Jenkins had suffered a stroke sometime after the first trial,
       which rendered him unable to recall the alleged admissions made to him by the defendant. He argued that
       Jenkins was unavailable as a witness and that Jenkins’
       testimony did not fit within the hearsay exceptions set
       forth in the Code of Evidence. Third, the trial court
       denied the defendant’s motion to exclude the testimony
       of Vazquez, another jailhouse informant. The defendant
       claimed that Vazquez’ testimony was unreliable.
         The defendant was tried again in 2022. The state
       presented a wide array of evidence, including inculpatory statements that were attributed to the defendant
       by Jenkins and Vazquez, which will be discussed in
       greater detail in this opinion. The defendant was again
       found guilty of murder, and the trial court sentenced
       him to sixty years of incarceration. This appeal followed.7 Additional facts and procedural history will be
       set forth as necessary.

       court violated his constitutional right to a probable

                                State v. Jacques

         cause hearing under article first, § 8, of the Connecticut
         constitution, as amended by article seventeen of the
         amendments, and General Statutes § 54-46a by denying
         his request for a second probable cause hearing after
         we reversed his previous conviction and remanded the
         case for a new trial.
           In January, 2016, prior to the first trial, the trial court
         held a probable cause hearing pursuant to § 54-46a.
         The court found probable cause to believe that the
         defendant had murdered Chadwick based on ‘‘the
         exhibits, the autopsy report, the DNA report, all the
         photographs, and the totality of the testimony and the
         evidence submitted during the hearing . . . .’’ The
         defendant declined to make an offer of proof pursuant
         to § 54-46a (b). The defendant also did not challenge
         the trial court’s probable cause finding.
             At a hearing before the second trial, defense counsel
         requested a new probable cause hearing. Defense counsel argued that, although the defendant already had a
         probable cause hearing before the first trial, he was
         entitled to a second one because this court reversed his
         prior conviction. By implication, he argued, the reversal
         ‘‘starts [the case] from scratch,’’ including the charges.
         The prosecutor disagreed, arguing that the defendant
         ‘‘is not entitled to an additional [probable cause] hearing’’ because, ‘‘[w]hile the trial starts from scratch, the
         case does not . . . .’’ The trial court agreed with the
         prosecutor, finding that the defendant already received
         a probable cause hearing. The trial court emphasized
         that the reversal was relative to one issue and that this
         court did not dismiss the defendant’s charges.
            On appeal, the defendant claims that, because the
         trial court relied on evidence at the probable cause
         hearing that we later held was improperly admitted
         at trial, § 54-46a required the trial court to grant the
         defendant a new probable cause hearing. The defendant

                              State v. Jacques

       contends that the trial court’s refusal to hold a second
       probable cause hearing warrants automatic reversal of
       his conviction. In response, the state argues that (1)
       the defendant’s first probable cause hearing satisfied
       the statutory requirement, and (2) the defendant’s argument lacks merit because the evidence improperly
       admitted at the first trial was nonetheless admissible
       at the probable cause hearing because the defendant
       was not entitled, under § 54-46a (b), to file a motion to
       suppress. We agree with the state.
          Because the defendant’s claim is premised on an
       alleged infringement of his constitutional rights, our
       review is plenary. See, e.g., State v. Douglas C., 
345 Conn. 421
, 435, 
285 A.3d 1067
 (2022).
         Article first, § 8, of the Connecticut constitution, as
       amended by article seventeen of the amendments, provides in relevant part that ‘‘[n]o person shall be held
       to answer for any crime, punishable by death or life
       imprisonment, unless upon probable cause shown at a
       hearing in accordance with procedures prescribed by
       law . . . .’’ In the 1983 legislative session, the legislature enacted § 54-46a ‘‘to institute the procedures necessary to implement article first, § 8, of the Connecticut
       constitution, as amended by article seventeen of the
       amendments . . . .’’ (Footnote omitted.) State v. Kane,
       
218 Conn. 151, 157
, 
588 A.2d 179
 (1991).
          A probable cause hearing held pursuant to § 54-46a
       is not only a constitutional right in Connecticut but ‘‘a
       jurisdictional prerequisite to continuing prosecution.’’
       State v. Mitchell, 
200 Conn. 323, 332
, 
512 A.2d 140
 (1986).
       Indeed, this provision ‘‘guarantees that no one will be
       forced to stand trial for a serious crime unless a court
       has first made a finding of probable cause at an open
       hearing in which the accused is provided with a full
       panoply of adversarial rights.’’ 
Id., 330
. We have emphasized that an ‘‘invalid finding of probable cause at [a

          probable cause hearing] undermines the court’s power
          to hear the case at trial.’’ 
Id., 332
. ‘‘We did not, in Mitchell, define precisely what defects would render a finding
          of probable cause ‘invalid,’ although implicit in our decision was an understanding that, at the very least, insufficiency of evidence presented at the probable cause
          hearing will deprive the trial court of jurisdiction
          . . . .’’ State v. McPhail, 
213 Conn. 161, 170
, 
567 A.2d 812
 (1989). In McPhail, we also concluded that a probable cause finding is invalid when ‘‘there has been a
          failure to disclose exculpatory evidence at a criminal
          defendant’s probable cause hearing,’’ but only if that
          failure to disclose ‘‘did in fact taint the defendant’s
          subsequent prosecution.’’ Id.; see also State v. White,
          
229 Conn. 125, 131, 136
, 
640 A.2d 572
 (1994) (reversing
          defendants’ convictions and remanding for new probable cause hearing because state failed to disclose exculpatory evidence that would have impeached testimony
          of state’s only witness).
             Although § 54-46a affords an accused with ‘‘a full
          panoply of adversarial rights’’; State v. 
Mitchell, supra,
200 Conn. 330
; we have made clear that ‘‘[a] probable
          cause hearing . . . was not designed to be a mini trial.’’
          (Internal quotation marks omitted.) State v. Conn, 
234 Conn. 97, 110
, 
662 A.2d 68
 (1995); see also State v.
          Rollinson, 
203 Conn. 641, 649
, 
526 A.2d 1283
 (1987) (‘‘a
          hearing in probable cause is necessarily more limited
          in scope than a full trial on the merits’’). That is precisely
          why § 54-46a (b) forbids the use of motions to suppress
          or for discovery in connection with such hearings. See
          State v. 
Conn, supra, 110
.
            In State v. 
Kane, supra,
218 Conn. 151
, this court
          addressed a constitutional challenge to § 54-46a in
          which the defendant claimed that he was deprived of
          due process of law because ‘‘the statute precluded a
          motion to suppress at his probable cause hearing and
          consequently deprived him of the opportunity to sup-
0, 0                   CONNECTICUT LAW JOURNAL                       Page 11

       press his allegedly involuntary statements to the police
       at that stage of the proceedings.’’ Id., 155. We rejected
       that argument on the basis that the defendant had an
       adequate opportunity to later challenge the allegedly
       illegally obtained evidence during the course of his trial.
       Id., 159. Indeed, we said that, ‘‘as long as the defendant
       was afforded the opportunity to challenge the admissibility of his statements at trial, the adjudicatory phase
       of the proceeding against him, his right to due process
       was preserved.’’ Id. We never suggested, however, that
       evidence that is later successfully challenged and
       excluded at trial would have any effect on the earlier
       probable cause determination or would otherwise
       require a new probable cause hearing. See id. (recognizing that ‘‘a damaging confession, which may later be
       suppressed at the trial level on the ground that it was
       involuntary and illegally obtained by the police, may be
       admitted at a preliminary hearing’’ (internal quotation
       marks omitted)).
          The defendant does not contest that a probable cause
       hearing was held prior to his first trial. Nor does he
       challenge the trial court’s finding of probable cause.
       Rather, the defendant essentially asks this court to hold
       that, because we reversed the defendant’s first conviction on the ground that the trial court improperly had
       admitted illegally obtained evidence, a second hearing
       in probable cause is required. In making this argument,
       the defendant implies that our holding in Jacques
       imputed a jurisdictional defect to his first hearing in
       probable cause that entitles him to a second one. We
       find no legal support for the defendant’s contention.
         First, the defendant’s argument confuses the scope
       of our decision in Jacques and the nature of § 54-46a
       hearings. In Jacques, we reversed the defendant’s conviction and remanded the case for a new trial in which
       the illegally obtained evidence would be excluded; we
       did not dismiss the charges. See State v. 
Jacques, supra,
Page 12                   CONNECTICUT LAW JOURNAL                      0, 0

                                State v. Jacques

          
332 Conn. 294
. Neither our state constitution nor § 54-
          46a requires a second probable cause hearing when this
          court reverses a criminal conviction.
             Second, the fact that a court later determines that
          illegally obtained evidence should have been excluded
          at trial has no impact on the earlier probable cause
          determination. See, e.g., State v. 
Kane, supra,
218 Conn.
          159
. Accordingly, our holding in Jacques affected only
          the admissibility of the evidence at retrial—it did not
          impair or vacate the earlier probable cause determination.
             Last, the defendant has not demonstrated that a jurisdictional defect exists that would render the first probable cause hearing invalid and entitle him to a second
          one. Notably, we have found no case in which we have
          required a new hearing in probable cause be held after
          we remanded the case for a new trial based on a trial
          court’s erroneous admission of improperly obtained evidence. See, e.g., State v. Oquendo, 
223 Conn. 635
, 660–
          61, 
613 A.2d 1300
 (1992) (not requiring new probable
          cause hearing when trial court improperly admitted
          identification and evidence obtained from illegal seizure); State v. Duntz, 
223 Conn. 207, 225
, 
613 A.2d 224
          (1992) (not requiring new probable cause hearing when
          trial court improperly admitted evidence obtained by
          illegal search).
            Because the defendant has already had a probable
          cause hearing and has not otherwise demonstrated a
          jurisdictional defect to the charges against him, we conclude that the trial court did not violate the defendant’s
          constitutional rights by declining his request for a second hearing in probable cause.
                                      III
            We turn next to the defendant’s constitutional and
          evidentiary claims that stem from the trial court’s
0, 0                          CONNECTICUT LAW JOURNAL                                       Page 13

       admission of Jenkins’ written statement to the police
       as a prior inconsistent statement under Whelan. The
       defendant’s primary claim is that the trial court violated
       his sixth amendment right to confrontation under the
       United States constitution by admitting Jenkins’ statement to the police because Jenkins’ alleged medical
       memory loss made him functionally unavailable at trial.8
       Alternatively, the defendant claims that, regardless of
       how this court decides the constitutional question, it
       should hold that the trial court abused its discretion in
       finding that Jenkins was available under Whelan because,
       unlike the witness in Whelan, Jenkins (1) could not
       explain the discrepancies between his prior statement
       and his testimony, and (2) never acknowledged that he
       signed the statement he made to the police. See State
       v. 
Whelan, supra,
200 Conn. 746
. The defendant further
       invites this court either (1) to adopt a prophylactic rule
       under our state constitution that provides that a witness
       is not considered available for cross-examination if, due
       to a valid medical condition, he has no memory of the
       incident and of making an out-of-court statement about
       the incident, or (2) to exercise our supervisory authority
       to modify Whelan and Connecticut Code of Evidence
       § 8-5 to preclude their application to situations in which
       a witness has a medical condition that causes total
       memory loss and is not trying to thwart justice or feign
       memory loss.
         On July 23, 2015, Jenkins made a written statement
       to the police. The statement detailed inculpatory state-
         8
            The defendant specifically states that he is not claiming our state constitution provides a broader confrontation right than the federal constitution.
       Rather, he argues that, if this court does not find a federal constitutional
       violation, we should nevertheless adopt a prophylactic rule under our state
       constitution in order to protect the right of confrontation thereunder, that
       provides that a witness is not considered available for cross-examination
       if, due to a valid medical condition, he has no memory of the incident and
       of making an out-of-court statement about the incident. We address, but
       ultimately reject, his request in part III C of this opinion.

          ments that the defendant allegedly made to Jenkins
          while the two were cellmates at Corrigan Correctional
          Center (Corrigan). Jenkins stated that the defendant
          had asked him if he could help write a statement to
          explain the defendant’s side of what happened to Chadwick. The defendant allegedly provided several versions
          of his account to Jenkins, the earlier versions pinning
          the death on a third party and the final version confessing that he had ‘‘snapped’’ and killed Chadwick, had
          tried to clean up the blood using a mop and bleach, had
          stolen Chadwick’s phone and drugs, and had planned
          on selling the drugs to the contacts he would find in
          Chadwick’s cell phone.
            During both a January, 2016 probable cause hearing
          and the defendant’s first murder trial, defense counsel
          cross-examined Jenkins regarding his statement to the
          police. The statement was not made a full exhibit at
          the probable cause hearing; it was made a full exhibit
          at the defendant’s first trial, during the prosecutor’s
          redirect examination of Jenkins, as a prior consistent
          statement. During both the probable cause hearing and
          the defendant’s first trial, Jenkins testified that the
          defendant had confessed to killing Chadwick and that
          Jenkins later provided a statement to the police detailing the defendant’s confession.
             After the defendant’s first trial and before testifying
          at the second trial, Jenkins suffered a stroke. Defense
          counsel moved to suppress Jenkins’ testimony prior to
          the commencement of the second trial on the basis of
          Jenkins’ memory loss due to the stroke, claiming that,
          ‘‘[d]ue to the fact that . . . Jenkins had a stroke, the
          change in circumstances, he is an unavailable witness
          and anything to replace him would be prejudicial.’’ The
          trial court considered the issue and determined that
          questions about the nature and scope of the testimony
          would be addressed as the evidence came in.

                              State v. Jacques

          When the prosecutor called Jenkins as a witness,
       defense counsel objected based on Jenkins’ memory
       loss. The court proposed that the witness take the stand
       and that the court would ‘‘see where the testimony
       goes,’’ ‘‘address any objections as soon as they’re raised’’
       and, if necessary, ‘‘take argument outside of the presence of the jury . . . .’’ Defense counsel agreed with
       the procedure. Jenkins walked into the courtroom,
       raised his right hand, and took an oath to tell the truth.
       On direct examination, Jenkins testified that he had
       received a subpoena from the state’s attorney’s office
       to testify and did not want to be in court. Jenkins
       recalled being incarcerated and being told that he had
       been convicted of a crime. Jenkins testified that he did
       not recall giving a statement to the police regarding
       information concerning Chadwick’s murder. He acknowledged that he had suffered a stroke that caused memory
       loss and that the stroke occurred two or three years
       earlier. The prosecutor then offered Jenkins’ 2015 statement to the police as a prior inconsistent statement
       under Whelan and § 8-5 of the Connecticut Code of
       Evidence.
         Defense counsel objected to the admission of Jenkins’ 2015 police statement, and the court heard arguments outside the presence of the jury. Defense counsel
       argued that admitting Jenkins’ testimony would violate
       the defendant’s sixth amendment right to confrontation
       under Crawford v. Washington, 
541 U.S. 36, 68
, 
124 S. Ct. 1354
, 
158 L. Ed. 2d 177
 (2004), describing Jenkins
       as having brain damage that is more than memory loss.
       Counsel further argued that the defendant lacked an
       opportunity to cross-examine Jenkins at the time Jenkins gave his statement to the police. In response, the
       prosecutor contended that, despite any memory loss,
       Jenkins was available because he was physically present and subject to cross-examination. The prosecutor
       further argued that, regardless of whether the defendant
Page 16                   CONNECTICUT LAW JOURNAL                      0, 0




          18                          ,0                 0 Conn. 1
                                State v. Jacques

          was available, defense counsel already had an opportunity to cross-examine Jenkins at the probable cause
          hearing and at the first trial. Therefore, the prosecutor
          argued that admitting Jenkins’ statement to the police
          did not violate the defendant’s right to confrontation.
             Defense counsel requested that the court canvass
          Jenkins to see if he understood the oath. The court
          instructed defense counsel that he was free to voir dire
          the witness. Counsel then asked Jenkins whether he
          knew what the oath was, and Jenkins responded in the
          affirmative. Counsel then asked Jenkins whether he
          knew that he could get in trouble if he did not follow
          the oath, to which Jenkins responded, ‘‘[y]es.’’ Defense
          counsel asked no further questions and did not probe
          the nature of the stroke or the extent of Jenkins’ memory loss. The court, relying on prior case law and the
          responses from Jenkins, including that Jenkins understood the oath and understood that he could get in
          trouble for not telling the truth, admitted the police
          statement into evidence. The court noted that, what it
          had seen was memory loss with respect to the statement
          and being incarcerated with the defendant, but that
          Jenkins was ‘‘adequately responding to the questions
          posed . . . .’’ The court ruled that Jenkins was not
          functionally unavailable.
             During trial, defense counsel cross-examined Jenkins
          regarding his recollection of his statement to the police.
          Jenkins again affirmed that he had a stroke but understood that taking the oath required him to tell the truth.
          When asked questions about his prior statement to the
          police, Jenkins repeatedly answered, ‘‘I don’t recall.’’
          He testified that he could not remember meeting the
          defendant, being cellmates with the defendant, hearing
          the defendant’s alleged confession, or making a statement to the police about the defendant’s alleged confession. But Jenkins remembered other details of his life.
          Jenkins said that, from what he understood, he had

       been in jail fourteen or fifteen times for minor offenses
       and agreed that jail was not pleasant. Defense counsel
       gave Jenkins a copy of the statement, and Jenkins said
       that he could read and understand it. When counsel
       asked Jenkins if he was okay to turn to page two by
       himself, Jenkins said, ‘‘[y]eah . . . I’m not crazy. You
       talking to me like I’m crazy. . . . I forget a lot. . . .
       But I do understand.’’ Jenkins read a portion of the
       statement and agreed that it said he was incarcerated.
       Jenkins then acknowledged that he had been incarcerated fourteen or fifteen times. When asked about whether
       he was incarcerated at the time of the statement, Jenkins said that he did not recall but all that he had been
       told was that he ‘‘was called a jailhouse snitch’’ and
       that he could not ‘‘see [his] grandchildren because it’s
       dangerous.’’ When asked if people would be upset if he
       made up information about people in prison to help
       himself, Jenkins said that he did not recall.
          After the defendant was convicted, he filed a motion
       for a new trial and raised, among other issues, that
       the admission of Jenkins’ 2015 police statement into
       evidence violated his sixth amendment right to confrontation. The trial court denied the motion and, in addressing
       the confrontation clause issue, specifically noted that
       it had the opportunity to observe Jenkins on the stand
       as well as his ability to testify. The court concluded
       that it stood by its findings, its reasoning, and the rulings
       on the record and that the admissibility of Jenkins’
       statement was not in violation of the defendant’s constitutional rights under Crawford or in violation of Whelan.
                                    A
          The defendant claims that the trial court violated
       his sixth amendment right to confrontation under the
       United States constitution because Jenkins’ memory
       loss stemming from his stroke rendered him functionally unavailable and made it impossible to confront

          Jenkins about his 2015 statement to the police. He
          acknowledges that, in United States v. Owens, 
484 U.S. 554
, 
108 S. Ct. 838
, 
98 L. Ed. 2d 951
 (1988), the United
          States Supreme Court held that a defendant’s right to
          confrontation is not violated when an out-of-court identification by a witness is introduced into evidence and
          that witness has no memory at trial of the basis for the
          identification. See 
id.,
 559–60. He argues, however, that
          Owens does not control here because there is a significant difference between the facts of Owens and the
          facts of the present case, namely, that the witness in
          Owens could testify about the events leading up to the
          attack in that case; see 
id., 556
; whereas Jenkins could
          not remember anything about the contents of his statement or that he ever gave a statement to the police.
          The defendant also argues that the facts of the present
          case are distinguishable from the facts of other cases
          in which this court rejected a defendant’s claim that a
          witness was functionally unavailable for confrontation
          clause purposes. See State v. Cameron M., 
307 Conn. 504
, 520–21, 
55 A.3d 272
 (2012) (overruled on other
          grounds by State v. Elson, 
311 Conn. 726
,

          (2014)), cert. denied,

547 U.S. 1197
, 
126 S. Ct. 2873
, 
165 L. Ed. 2d 904
 (2006). He argues that the
          relevant federal and state cases that have permitted the
          introduction of hearsay statements have addressed only
          situations in which a witness remembers either making
          a police statement or the events that gave rise to the
          statement.
             The state contends that, although the defendant
          attempts to distinguish the facts of the present case
          from other cases in which courts have determined that a
          witness was available for purposes of the confrontation
          clause, the defendant ignores the fact that the sixth
          amendment guarantees only an opportunity to probe
0, 0                        CONNECTICUT LAW JOURNAL                                     Page 19

       and expose infirmities through cross-examination; it
       does not guarantee that cross-examination is effective
       in whatever way, and to whatever extent, the defense
       might wish. Because Jenkins took the witness stand,
       took an oath, and willingly answered all the questions
       put to him on cross-examination, the state contends
       that he was available for confrontation clause purposes.
       For the reasons discussed herein, we conclude that
       Jenkins was available for cross-examination and that
       the defendant’s confrontation clause claim fails.
          Although we generally ‘‘review the trial court’s decision to admit evidence, if premised on a correct view
       of the law . . . for an abuse of discretion’’; (internal
       quotation marks omitted) State v. Beavers, 
290 Conn. 386, 396
, 
963 A.2d 956
 (2009); we have explained that
       ‘‘the abuse of discretion standard is at odds with the
       axiomatic principle that question[s] of constitutional
       law . . . [are] subject to plenary review.’’ (Internal
       quotation marks omitted.) State v. Lebrick, 
334 Conn. 492
, 505, 
223 A.3d 333
 (2020). In Lebrick, we concluded
       that the question of availability under the sixth amendment confrontation clause is a mixed question of law
       and fact subject to plenary review. 
Id.
 Accordingly, the
       trial court’s subordinate factual findings regarding the
       availability of a witness will not be disturbed unless
       they are clearly erroneous and the trial court’s ultimate
       legal conclusion that a witness is constitutionally available, in light of the facts found, will be reviewed de
       novo. 
Id., 506
.
          The confrontation clause of the sixth amendment of
       the United States constitution affords ‘‘the accused’’ in
       ‘‘all criminal prosecutions’’ a right ‘‘to be confronted

          The sixth amendment right to confrontation is applicable to the states
       through the due process clause of the fourteenth amendment to the United

Jacques 36
, the United States Supreme Court altered the
          approach to the confrontation clause that it had previously followed. See 
id.,
 68–69. After considering the
          historical underpinnings of the confrontation clause,
          the court overruled its decision in Ohio v. Roberts, 
448 U.S. 56
, 
100 S. Ct. 2531
, 
65 L. Ed. 2d 597
 (1980), which
          had interpreted the confrontation clause to permit the
          admission of out-of-court statements by an unavailable
          witness so long as the statements ‘‘[bore] adequate indicia of reliability’’; (internal quotation marks omitted)
          
id., 66
; and adopted a rule that hearsay labeled as ‘‘[t]estimonial’’ shall not be admitted into evidence unless
          the witness appears at trial for cross-examination or,
          if the witness is unavailable, the defendant had a prior
          opportunity for cross-examination.10 Crawford v. Wash-
          
ington, supra, 59, 68
; see also State v. Rivera, 
268 Conn. 351, 362
, 
844 A.2d 191
 (2004) (explaining that Crawford
          overruled reliability approach set forth in Roberts for
          testimonial statements). Although Crawford left open
          many questions about how to define a testimonial statement, the decision did nothing to alter the court’s prior
          jurisprudence on unavailability. See Crawford v. Wash-
          
ington, supra, 68
. Indeed, nothing in the decision purported to overrule or call into question the pre-Crawford cases in which the court addressed memory
          loss in the confrontation clause context. It is those
          pre-Crawford cases that are pertinent to the question
          presented in the present case.
            In California v. Green, 
399 U.S. 149
, 
90 S. Ct. 1930
,
          
26 L. Ed. 2d 489
 (1970), a sixteen year old declarant
          reported, in both a police interview and at a preliminary
          hearing, that the defendant was his marijuana supplier.
          
Id., 151
. At trial, however, the declarant claimed that
          he could not remember how he received the marijuana
          because he had taken LSD (lysergic acid diethylamide)
           10
              The parties agree that Jenkins’ 2015 statement to the police was testimonial.

       on the day it was delivered. 
Id., 152
. The prosecutor
       proceeded to introduce the declarant’s statements from
       the preliminary hearing and the police interview. 
Id.
       The declarant admitted to making the prior statements
       and insisted that he had been telling the truth as he
       then believed it, but he also testified that he was telling
       the truth on the stand in claiming his inability to remember the actual events. 
Id.
          The United States Supreme Court explained that ‘‘the
       [c]onfrontation [c]lause is not violated by admitting a
       declarant’s out-of-court statements, as long as the
       declarant is testifying as a witness and subject to full
       and effective cross-examination.’’ 
Id., 158
. The court
       further explained that the confrontation clause ‘‘does
       not require excluding from evidence the prior statements of a witness who concedes making the statements, and who may be asked to defend or otherwise
       explain the inconsistency between his prior and his
       present version[s] of the events in question, thus opening himself to full cross-examination at trial as to both
       stories.’’ 
Id., 164
. The declarant’s preliminary hearing
       testimony was deemed admissible, but the court declined
       to address whether the declarant’s purported loss of
       memory so affected the defendant’s right to cross-examination as to ‘‘make a critical difference’’ in the application of the confrontation clause because that issue was
       not yet ripe. 
Id.,
 168–69.
          In a concurring opinion, Justice John Marshall Harlan
       II opined that ‘‘[t]he fact that the witness, though physically available, cannot recall either the underlying
       events that are the subject of an extra-judicial statement
       or previous testimony or recollect the circumstances
       under which the statement was given, does not have
       [s]ixth [a]mendment consequence. The prosecution has
       no less fulfilled its obligation simply because a witness
       has a lapse of memory. The witness is, in my view,
       available. To the extent that the witness is, in a practical

          sense, unavailable for cross-examination on the relevant facts . . . I think confrontation is nonetheless satisfied.’’ 
Id.,
 188–89 (Harlan, J., concurring).
             Fifteen years after Green, the United States Supreme
          Court had the opportunity to consider whether admitting opinion testimony from a state’s expert—‘‘who was
          unable to recall the basis for his opinion’’—violated the
          confrontation clause. Delaware v. Fensterer, 
474 U.S. 15, 16
, 
106 S. Ct. 292
, 
88 L. Ed. 2d 15
 (1985). In Fensterer,
          the defendant was convicted of murdering his fiancée.
          
Id.
 To establish that a cat leash was the murder weapon,
          the state sought to prove that two hairs found on the
          leash were similar to the fiancée’s hair, and that one
          of those hairs had been forcibly removed. 
Id.
 To prove
          that the hairs were forcibly removed, the state relied
          on the testimony of an agent with the Federal Bureau
          of Investigation (FBI). 
Id.
 The agent testified that one
          of the hairs was forcibly removed and explained that
          ‘‘there are three methods of determining that a hair has
          forcibly been removed . . . .’’ 
Id.,
 16–17. The agent,
          however, went on to say, ‘‘I have reviewed my notes,
          and I have no specific knowledge as to the particular
          way that I determined the hair was forcibly removed
          other than the fact that one of those hairs was forcibly
          removed.’’ (Internal quotation marks omitted.) 
Id., 17
.
          On cross-examination, the agent again was unable to
          remember which method he had employed to determine
          that the hair was forcibly removed. 
Id.
 The Delaware
          Supreme Court concluded that there was a confrontation clause violation because ‘‘[e]ffective cross-examination and discrediting of [the special agent’s] opinion
          at a minimum required that he commit himself to the
          basis of his opinion.’’ (Internal quotation marks omitted.) 
Id., 18
.
            The United States Supreme Court disagreed. It held
          that, in general, the confrontation clause ‘‘guarantees an
          opportunity for effective cross-examination, not cross-

                              State v. Jacques

       examination that is effective in whatever way, and to
       whatever extent, the defense might wish.’’ (Emphasis in
       original.) 
Id., 20
. It explained that ‘‘[t]he [c]onfrontation
       [c]lause includes no guarantee that every witness called
       by the prosecution will refrain from giving testimony
       that is marred by forgetfulness, confusion, or evasion.
       To the contrary, the [c]onfrontation [c]lause is generally
       satisfied when the defense is given a full and fair opportunity to probe and expose these infirmities through
       cross-examination, thereby calling to the attention of
       the [fact finder] the reasons for giving scant weight to
       the witness’ testimony.’’ 
Id.,
 21–22. The court noted
       that, in that case, defense counsel’s cross-examination
       of the special agent ‘‘demonstrated to the jury that [he]
       could not even recall the theory on which his opinion
       was based’’ and that ‘‘the defense was able to suggest
       to the jury that [the special agent] had relied on a theory
       [that] the defense expert considered baseless.’’ 
Id., 20
.
       The court nevertheless indicated that it did not need
       to decide in that case ‘‘whether there are circumstances
       in which a witness’ lapse of memory may so frustrate
       any opportunity for cross-examination that admission
       of the witness’ direct testimony violates the [c]onfrontation [c]lause.’’ 
Id.
          Then came the United States Supreme Court’s decision in Owens, which required it to squarely consider
       whether the confrontation clause barred testimony
       regarding a previous, out-of-court identification ‘‘when
       the identifying witness [was] unable, because of memory loss, to explain the basis for the identification.’’
       United States v. 
Owens, supra,
 484 U.S. 555–56. There,
       a correctional counselor at a federal prison was beaten
       with a metal pipe, which resulted in injuries that
       severely impaired his memory. 
Id., 556
. When the counselor first spoke with the FBI, he was unable to remember his attacker’s name. 
Id.
 A few weeks later, in a
       second interview with the FBI, he was able to describe

                                 State v. Jacques

          the attack, name his attacker, and identify his attacker
          from an array of photographs. 
Id.
 At trial, the counselor
          recounted his activities just prior to the attack,
          described feeling blows to his head, and recalled seeing
          blood on the floor. 
Id.
 He also clearly remembered
          identifying the defendant as his assailant during the
          second interview. 
Id.
 On cross-examination, however,
          the counselor acknowledged that ‘‘he could not remember seeing his assailant’’ at the time of the assault. 
Id.
          And, ‘‘although there was evidence that he had received
          numerous visitors in the hospital,’’ he could remember
          visits from only one of them; he ‘‘could not remember
          whether any of these visitors had suggested that [the
          defendant] was the assailant.’’ 
Id.
 Although defense counsel ‘‘sought to refresh [the counselor’s] recollection with
          hospital records, including one indicating that [he] had
          attributed the assault to someone other than [the defendant],’’ these attempts to refresh the counselor’s recollection were unsuccessful. 
Id.
             The United States Supreme Court concluded that the
          confrontation clause was not violated by the counsel- or’s memory loss. 
Id.,
 559–60. It began by stating that
          it ‘‘has never held that a [c]onfrontation [c]lause violation’’ could be founded on the basis of a witness’ loss
          of memory. 
Id., 557
. After reviewing its decisions in
          Green and Fensterer, the court indicated that it ‘‘agree[d]
          with the answer suggested 18 years ago by Justice Harlan’’ in Green. 
Id., 559
. The confrontation clause, the
          court stated, ‘‘guarantees only an opportunity for effective cross-examination, not cross-examination that is
          effective in whatever way, and to whatever extent, the
          defense might wish.’’ (Emphasis in original; internal
          quotation marks omitted.) 
Id.
 The opportunity for cross-examination, the court reasoned, ‘‘is not denied when
          a witness testifies as to his current belief but is unable
          to recollect the reason for that belief. It is sufficient
          that the defendant has the opportunity to bring out

                             State v. Jacques

       such matters as the witness’ bias, his lack of care and
       attentiveness, his poor eyesight, and even (what is often
       a prime objective of cross-examination . . . ) the very
       fact that he has a bad memory.’’ (Citation omitted.) 
Id.
       The court recognized that ‘‘[t]he weapons available to
       impugn the witness’ statement when memory loss is
       asserted will of course not always achieve success, but
       successful cross-examination is not the constitutional
       guarantee.’’ 
Id., 560
. The court explained, however, that,
       if a witness asserts memory loss, a defendant may still
       have ‘‘realistic weapons’’ to attack a witness’ statement.
       
Id.
 The court observed that defense counsel in that very
       case emphasized during summation the counselor’s
       memory loss and ‘‘argued that [the counselor’s] identification of [the defendant] was the result of the suggestions of people who visited him in the hospital.’’ 
Id.
 The
       court concluded that, when the ‘‘declarant is present
       at trial and subject to unrestricted cross-examination,’’
       there was no need to evaluate the reliability of the prior
       out-of-court statement. 
Id.
          Although Green, Fensterer, and Owens predated the
       United States Supreme Court’s decision in Crawford,
       nothing in Crawford, as we have explained, explicitly
       overruled or called into question the vitality of these
       cases. See State v. 
Pierre, supra,
277 Conn. 82
 (acknowledging that ‘‘Crawford neither overruled nor called into
       question its . . . earlier decisions that addressed and
       resolved [the memory loss] issue’’ (internal quotation
       marks omitted)). The defendant, however, points to
       footnote 9 in Crawford, which provides in relevant part
       that the confrontation clause ‘‘does not bar admission
       of a statement so long as the declarant is present at
       trial to defend or explain it,’’ suggesting that a witness
       who has memory loss cannot ‘‘defend or explain’’ his
       statement and is therefore unavailable for confrontation
       clause purposes. Crawford v. 
Washington, supra,
541
       U.S. 60
 n.9. By focusing on this sentence in isolation,

                                State v. Jacques

          the defendant fails to consider the statement in its full
          context. Immediately preceding that sentence is the
          unambiguous statement from the court that, ‘‘when the
          declarant appears for cross-examination at trial, the
          [c]onfrontation [c]lause places no constraints at all on
          the use of his prior testimonial statements.’’ 
Id.,
 citing
          California v. 
Green, supra,
399 U.S. 162
. Since Crawford, the court has reiterated that a witness’ ‘‘testimony
          against a defendant is thus inadmissible unless the witness appears at trial or, if the witness is unavailable,
          the defendant had a prior opportunity for cross-examination.’’ Melendez-Diaz v. Massachusetts, 
557 U.S. 305, 309
, 
129 S. Ct. 2527
, 
174 L. Ed. 2d 314
 (2009). Although
          we recognize that the United States Supreme Court
          has not addressed what constitutes ‘‘availability’’ postCrawford, there is nothing in Crawford that indicates
          that the court intended to overrule or alter its prior
          memory loss jurisprudence.
             Since Crawford, virtually every court that has been
          confronted with a memory loss claim has followed the
          Owens approach and concluded that a declarant’s
          appearance and subjection to cross-examination at trial
          is generally all that is necessary to pass muster under
          the confrontation clause. See, e.g., United States v.
          Shaffers, 
22 F.4th 655
, 661–62 (7th Cir. 2022) (rejecting
          defendant’s argument that Crawford changed Owens’
          approach to cases of claimed memory loss and concluding ‘‘that the [c]onfrontation [c]lause is satisfied when
          the witness must look the accused in the eye in court;
          shortcomings in the declarant’s memory may be made
          known to the jury’’ (internal quotation marks omitted));

 (2008).11 Indeed, this court said as much in State v.
       
Pierre, supra,
277 Conn. 79
. In Pierre, we addressed
       the issue of whether the admission of a witness’ prior
       inconsistent written statement to the police violated
       the defendant’s right to confrontation when the witness
       claimed at trial that he could not remember ever having
       heard any of the information recounted in the written
       statement, that he never had substantively reviewed the
       statement, and that he had signed the statement only
       to stop the police from harassing him. 
Id.,
 78–79. In
       other words, we had to determine whether a witness
       who testifies at trial and is subject to cross-examination
       is nevertheless ‘‘functionally unavailable’’ for purposes
       of the confrontation clause due to the witness’ loss of
       memory. (Internal quotation marks omitted.) 
Id., 80
.
          In concluding that there was no confrontation clause
       violation, we relied on our previous Whelan jurisprudence and sister state decisions that had interpreted
       Crawford’s availability element; 
id.,
 81–84; holding that
       ‘‘a witness’ claimed inability to remember earlier state-
         11
            It appears that only one state supreme court, in interpreting its own
       constitution, has found that total memory loss of a witness can run afoul
       of its state constitution’s confrontation clause. See Goforth v. State, 
70 So. 3d 174, 183, 187
 (Miss. 2011) (‘‘[because] [a]rticle 3, [§] 26 of the Mississippi
       [c]onstitution provides defendants a constitutional right to confront the
       witnesses against them, we base our opinion on its provisions’’ and ‘‘find
       that, under the Mississippi [c]onstitution, [the defendant] did not have a
       constitutionally adequate opportunity to cross-examine [the witness] at trial
       or beforehand’’).

          ments or the events surrounding those statements does
          not implicate the requirements of the confrontation
          clause under Crawford, so long as the witness appears
          at trial, takes an oath to testify truthfully, and answers
          the questions put to him or her during cross-examination.’’ Id., 86. We agreed with the jurisdictions interpreting ‘‘ ‘availability for cross-examination’ under Crawford
          as needing to be synthesized with the United States
          Supreme Court’s holdings in [Owens and Fensterer]
          . . . .’’ (Citations omitted.) Id. We acknowledged that,
          ‘‘although ‘availability’ was not defined in Crawford,
          Owens and Fensterer [nevertheless] make clear that
          the right to cross-examination does not imply a right
          to cross-examination that is effective in whatever way,
          and to whatever extent, the defense might wish.’’ Id.
          We therefore concluded that, because the witness ‘‘took
          the stand at trial, agreed to testify truthfully, was subject
          to cross-examination by the defendant, and answered
          all questions posed by defense counsel’’; id., 84; there
          was no confrontation clause violation. Id., 86. We further explained that there was no confrontation clause
          violation because of the substance of the witness’ testimony. See id., 85–86. In particular, we emphasized that
          the witness’ testimony regarding details he could remember about his statement to the police ‘‘provided the
          defendant with the opportunity to show [the witness’]
          bias, interest, potential motives and demeanor as a witness.’’ Id., 86.
             Here, the trial court determined that Jenkins was
          available for cross-examination. Like the witness in
          Pierre, Jenkins appeared at trial, took an oath to testify
          truthfully, testified that he understood the oath and the
          implications of not telling the truth, and answered the
          questions put to him during cross-examination. See id.
          We need not decide, however, whether those facts
          alone, in the context of the facts of the present case,
          would be sufficient to establish availability for confron-
0, 0                   CONNECTICUT LAW JOURNAL                       Page 29

                              State v. Jacques

       tation clause purposes, or whether the extent of Jenkins’ memory loss is even relevant to that analysis,
       because the defendant also had the means to impugn
       the foundation of Jenkins’ belief expressed in his prior
       statement.
           Defense counsel, for example, could have cross-examined Jenkins regarding his prior testimony at the
       probable cause hearing and the first trial, and could
       have sought to admit any portions of that testimony
       that were inconsistent with Jenkins’ asserted lack of
       memory at the second trial. See Conn. Code Evid. § 8-
       5 (1); see also part III B of this opinion. With that prior
       testimony, defense counsel could have established,
       among other things, that (1) Jenkins had difficulty communicating with the defendant due to the defendant’s
       thick Haitian accent and his nonlinear thinking, (2) Jenkins lied to the defendant about the existence of forensic evidence implicating the defendant in the crime
       ‘‘[t]o see if [the defendant] had really [done] it,’’ (3)
       the defendant told Jenkins ‘‘seven or eight’’ different
       versions of what happened, but the written statement
       provided ‘‘[t]he best one,’’ and (4) the written statement
       did not include all of the information that Jenkins had
       conveyed to the police about his conversations with
       the defendant.
          Defense counsel also could have highlighted during
       cross-examination that Jenkins not only did not want
       to testify at the trial but also did not like being labeled
       a jailhouse snitch, which calls into question the extent
       of his memory loss and his motive for testifying; emphasized that, based on Jenkins’ limited memory and because
       he did not personally write the statement, Jenkins could
       not say at the time of the second trial whether the police
       had completely fabricated the information; pointed to
       key details Jenkins previously testified to knowing but
       had left out of his statement; and argued that the police
       statement was as unreliable as Jenkins’ memory argua-

          bly was. Moreover, the trial court instructed the jury
          on the heightened scrutiny required when evaluating
          jailhouse informant testimony—an additional layer that
          was absent in Pierre. Simply put, defense counsel was
          not without tools to probe Jenkins’ lack of memory or
          to try to cast doubt on his earlier statement to the
          police. See, e.g., State v. 
Pierre, supra,
277 Conn. 81
          (‘‘defense counsel was not without resources’’ in crossexamining witness (internal quotation marks omitted));
          see also United States v. 
Owens, supra,
484 U.S. 560
          (explaining that defendants may have ‘‘realistic weapons’’ to attack witness’ statement when memory loss
          is asserted).
             On this factual record, we conclude that the trial
          court correctly determined that Jenkins was available
          for confrontation clause purposes because (1) Jenkins
          appeared at trial, took an oath to testify truthfully, and
          answered all the questions put to him during cross-examination, and (2) defense counsel had tools available to cross-examine Jenkins, namely, the opportunity
          to ask Jenkins questions about his prior testimony
          regarding his statement to the police. Like the United
          States Supreme Court in Green, Fensterer, and Owens,
          we do not need to address in the present case whether
          there may be circumstances in which a witness, because
          of the nature and extent of a medical condition and
          its impact on memory, is unavailable for confrontation
          clause purposes. Although trial courts should, when
          requested, hold a pretrial evidentiary hearing to consider medical evidence that may establish that a valid
          medical condition so frustrates the opportunity for
          cross-examination that the witness is functionally
          unavailable, this is not such a case.

          of Jenkins’ statement did not violate his sixth amend-

       ment rights, the trial court nevertheless abused its discretion in admitting Jenkins’ statement under Whelan
       and § 8-5 of the Connecticut Code of Evidence. We
       disagree.
          It is well known that this court ‘‘review[s] the trial
       court’s decision to admit evidence, if premised on a
       correct view of the law . . . for an abuse of discretion.’’
       (Internal quotation marks omitted.) State v. Smith,

       omitted.) State v. Qayyum, 
344 Conn. 302

279 A.3d 172
 (2022).
          In State v. 
Whelan, supra,
200 Conn. 743
, we held
       that the substantive use of a prior written inconsistent
       statement is permitted, provided that the statement has
       been ‘‘signed by the declarant, who has personal knowledge of the facts stated, when the declarant testifies at
       trial and is subject to cross-examination.’’ 
Id., 753
. This
       rule has been codified at § 8-5 of the Connecticut Code
       of Evidence.12 It is well settled that ‘‘changes in position,’’ ‘‘denial[s] of recollection,’’ and ‘‘omissions’’ can
       satisfy the inconsistency element of Whelan. (Emphasis
       omitted; internal quotation marks omitted.) State v.
       
Simpson, supra,
286 Conn. 649
; see also State v. 
Whelan, supra,
 748–49 n.4. For a prior inconsistent statement
       to be admitted under Whelan and § 8-5, however, the
       declarant must be available to testify at trial and be
       subject to cross-examination. E.g., State v. 
Whelan, supra,
 750–53.
         12
            Section 8-5 of the Connecticut Code of Evidence provides in relevant
       part: ‘‘The following are not excluded by the hearsay rule, provided the
       declarant is available for cross-examination at trial:
         ‘‘(1) Prior inconsistent statement. A prior inconsistent statement of a
       witness, provided (A) the statement is in writing or otherwise recorded by
       audiotape, videotape or some other equally reliable medium, (B) the writing

             In part III A of this opinion, we concluded that the
          trial court had correctly determined that Jenkins was
          available for cross-examination at trial for purposes of
          the confrontation clause. For the same reasons, we
          conclude that Jenkins was also available for purposes of
          Whelan and § 8-5 of the Connecticut Code of Evidence.13
          The defendant nevertheless argues that two of the other
          requirements of Whelan and § 8-5 were not satisfied.
          Specifically, he argues that Jenkins (1) could not explain
          the discrepancies between his prior statement and his
          testimony, and (2) never acknowledged that he signed
          the statement he made to the police. These arguments
          are unavailing.14
             First, although the defendant contends that Jenkins
          could not explain the discrepancies between his prior
          statement and his testimony, the defendant concedes
          that Whelan plainly states that a denial of recollection
          or a claim of memory loss can serve as the basis for a
          finding of inconsistency. See id., 748 n.4. Therefore, the
            13
               We note that the defendant argues that Jenkins was unavailable under
          both Crawford and Whelan. Although this could be construed as suggesting
          that availability under Crawford and Whelan differs, the defendant did not
          make this argument before the trial court and does not explain on appeal
          how a defendant can be ‘‘available’’ for purposes of Crawford and the
          confrontation clause but nevertheless be ‘‘unavailable’’ for purposes of
          Whelan. As such, we need not decide whether there may ever be a circumstance involving medical memory loss in which the definition of ‘‘availability’’
          for purposes of Whelan is not coterminous with the meaning of ‘‘availability’’
          under Crawford.
            14
               On appeal, the defendant notes that he does not claim that the trial
          court abused its discretion on the ground that Jenkins’ genuine lack of
          memory was not inconsistent with his prior statement under Whelan because
          he did not raise such a claim before the trial court. Nevertheless, we note
          that we have expressly rejected any distinction between feigned and genuine
          memory loss under Whelan. See, e.g., State v. Cameron M., supra, 
307 Conn. 527
 (rejecting proposition that ‘‘whether the Whelan rule should be limited
          to feigned loss of memory, rather than the genuine loss of memory experienced by the victim . . . remains an open question’’). Although the defendant has asked us to invoke our supervisory authority to modify Whelan
          and § 8-5 of the Connecticut Code of Evidence; see part III D of this opinion;
          he has not asked that we overrule Cameron M.

       fact that Jenkins was not able to explain the discrepancies due to his memory loss did not preclude admission
       of the statement under Whelan. Second, although counsel raised an objection to Jenkins’ availability under
       Whelan and the confrontation clause, he represented to
       the court that Detective Anthony Gomes of the Norwich
       Police Department had typed up the statement, that
       Gomes had given it to Jenkins, and that Jenkins had
       signed it, effectively conceding those points. Because
       all of the requirements of Whelan and § 8-5 of the Connecticut Code of Evidence were satisfied, we conclude
       that the trial court did not abuse its discretion in admitting Jenkins’ statement.
                                              C
          In the alternative, the defendant asks that we adopt
       a state constitutional prophylactic rule that provides
       that a witness is not considered available for cross-examination if, due to a valid medical condition, he has
       no memory of the incident or of making an out-of-court
       statement about the incident. The defendant contends
       that, because medical memory loss would prevent a
       defendant from obtaining any meaningful information
       from the witness during cross-examination, a jury could
       not accurately determine the witness’ credibility. Thus,
       the defendant argues that applying the prophylactic rule
       in such situations would ‘‘prevent the significant risk
       of a constitutional violation . . . .’’15 (Citation omitted;
          15
             The defendant does not argue that the confrontation clause in article
       first, § 8, of our state constitution provides any greater protection than the
       confrontation clause of the federal constitution. See State v. Lockhart, 
298 Conn. 537, 555
, 
4 A.3d 1176
 (2010) (‘‘[W]ith respect to the right to confrontation within article first, § 8, of our state constitution, its language is nearly
       identical to the confrontation clause in the sixth amendment to the United
       States constitution. The provisions have a shared genesis in the common
       law.’’). Rather, the defendant is asking this court to craft a prophylactic rule
       that arguably provides greater protection than what the state constitution
       requires. The defendant and the state address this request under the six
       factors that we set forth in State v. Geisler, 
222 Conn. 672
, 684–85,

          A. B., 
342 Conn. 489
, 508, 
270 A.3d 656
 (2022). We have previously recognized
          that it may not be necessary to consider the Geisler factors in deciding
          whether to adopt a prophylactic rule because the analytical process in
          deciding whether to adopt such a rule necessarily involves a policy centered
          weighing process. See State v. Purcell, 
331 Conn. 318
, 343 n.16,

336 A.3d 1139
          (2025) (policy centered weighing process is embedded in Geisler analysis
          as sixth factor). In the present case, we focus on the sixth Geisler factor
          and ask whether a judicially created rule or an additional layer of prophylaxis, rather than a case-by-case analysis, is necessary to protect the constitutional right. We note, however, that the result, based on a consideration of
          all of the Geisler factors, for the reasons articulated in part III A of this
          opinion, would be the same.

       Rogers, supra, 547. Because constitutional prophylactic
       rules have this potential to prohibit or to mandate what
       the constitution does not, their adoption is justified
       only when the risk of a constitutional violation is high,
       i.e., when the constitutional protections are ‘not by their
       terms readily applicable in the field’ . . . id., 553; or
       when case-by-case analysis by the courts is inadequate
       due to the lack of ‘judicially manageable standards.’ Id.,
       554. Thus, ‘the authority . . . to create prophylactic
       rules is not without limits. To the contrary, there is
       general agreement that [courts] should use this authority cautiously and rules should be as narrowly tailored
       as possible to accomplish their purpose.’ Id., 565.’’ State

 (2024).
          With this general background in mind, we turn to the
       defendant’s claim that we should adopt a prophylactic
       rule that witnesses who have medical memory loss are
       unavailable if, due to that memory loss, they cannot
       remember making the out-of-court statement or the
       circumstances surrounding the statement. Although we
       recognize that a witness’ memory loss can pose real
       challenges and can conceivably result in a constitutional violation under certain circumstances, we are
       not persuaded that the risks, as articulated by the defendant in his brief, warrant the adoption of a categorical
       prophylactic rule for which the defendant advocates,
       especially when it is not clear that such a rule would
       accomplish what a case-by-case analysis could not.
         First, we note that neither the United States Supreme
       Court nor this court has ever drawn a distinction based
       on the reason for the memory loss, as the defendant
       does in the present case. Rather, both courts have suggested that memory loss, whether genuine or feigned,
       medical or otherwise, is an issue of credibility and
       weight for the jury. See, e.g., Bullcoming v. New Mexico,

          Cir. 1997) (explaining that confrontation clause does
          not distinguish between genuine and feigned memory
          loss and that confrontation clause is satisfied when
          witness ‘‘look[s] the accused in the eye in court’’), cert.

          friends), the issue is one of credibility that is left for
          the jury’’).
              Second, even if it is proper to single out memory loss
          stemming from a medical condition from other types
          of memory loss, it is not clear to us what the defendant
          means by the phrase ‘‘valid medical condition’’ in advancing his proposed rule. Although memory loss stemming
          from a stroke may fall within his proposed rule, would
          the nature of the stroke not be relevant? Would memory
          loss stemming from old age fall under the rule? What
          if the witness claims that he has poor memory or a lack
          of memory because he previously hit his head? The
          questions that remain are numerous, and the line drawing required is difficult. The proposed rule neither provides clear guidance nor is it aimed at government
          misconduct. See C. Rogers, supra, 98 B.U. L. Rev. 553–54
          (‘‘[b]y providing clear guidelines for official conduct,
          ‘prophylactic rules build a fence around the [c]onstitu-

                              State v. Jacques

       tion’ ’’). We are therefore not confident that the rule for
       which the defendant advocates is sufficiently tailored to
       ameliorate the alleged risk of constitutional violations.
       Rather than craft a rule that may be overinclusive or
       underinclusive, we think the better approach is to allow
       trial courts, on a case-by-case basis, to determine whether
       a valid medical condition so frustrates the opportunity
       for cross-examination that the witness is functionally
       unavailable.
         In short, although we are cognizant that memory loss
       and forgetfulness can raise complex problems in the
       courtroom, we are not persuaded that it is necessary
       or appropriate at this time to adopt the defendant’s
       proposed rule.
                                    D
          The defendant makes a final request. He asks that
       we exercise our supervisory authority to modify Connecticut Code of Evidence § 8-5 to preclude its application to situations in which a witness has a medical
       condition that causes total memory loss. The defendant
       argues that, when a witness has medical memory loss
       to the extent that he cannot remember making the out-of-court statement or the circumstances surrounding
       the statement, there is no basis to determine that the
       lack of memory constitutes an inconsistency under Connecticut Code of Evidence § 8-5.
          The state argues that we should decline to exercise
       our supervisory authority because the defendant’s proposed modification to the Code of Evidence is a matter
       of substantive law rather than judicial procedure. The
       state further argues that the rule is unnecessary because
       trial judges are best situated to evaluate whether a prior
       statement is inconsistent with contemporaneous testimony. Finally, the state argues that ‘‘the record is inadequate to demonstrate that Jenkins . . . is a diminished
       witness . . . .’’

       that the traditional protection afforded when a trial
       judge exercises his or her discretion to determine
       whether medical memory loss constitutes a basis for
       finding inconsistency is ‘‘inadequate to ensure the fair

. We do not rule out that there may be circumstances
       in which, due to the nature and extent of a witness’
       medical memory loss, the trial court in the exercise of
       its considerable discretion concludes that the witness’
       prior statement is not admissible under Whelan, either
       because the statement is not inconsistent with the witness’ testimony or because the witness is unavailable
       for cross-examination.16 ‘‘Whether there are inconsistencies between the two statements is properly a matter
       for the trial court. . . . Inconsistencies may be shown
       not only by contradictory statements but also by omissions. In determining whether an inconsistency exists,
       the testimony of a witness as a whole, or the whole
       impression or effect of what has been said, must be
       examined. . . . Inconsistency in effect, rather than
       contradiction in express terms, is the test for admitting a witness’ prior statement . . . and the same principle governs the case of the forgetful witness. . . . A
       statement’s inconsistency may be determined from the
       circumstances and is not limited to cases in which diametrically opposed assertions have been made. Thus,
       inconsistencies may be found in changes in position
       and they may also be found in denial of recollection.’’
       (Emphasis omitted; internal quotation marks omitted.)
         16
            As previously noted, the defendant has failed to preserve any claim that
       Jenkins’ lack of memory was not inconsistent with his prior statement under
       Whelan. See footnote 14 of this opinion. Accordingly, we need not—and do
       not—decide whether there may ever be a circumstance in which a witness’
       medical condition and its effect on memory may render a statement not
       inconsistent for purposes of Whelan.

. Thus, the concerns raised by the defendant are adequately addressed
          under the present analytical framework of the Whelan
          rule, and he has not demonstrated, and our research
          has not revealed, that trial judges are improperly (and
          frequently) admitting evidence based on inconsistency
          when the witness has total memory loss, so as to call
          it a problem that is ‘‘pervasive and significant,’’ warranting this court’s intervention. (Internal quotation

          For these reasons, we decline the defendant’s invitation
          to exercise our supervisory authority.
                                       IV
             Finally, we turn to the defendant’s claim that the trial
          court abused its discretion in finding that the state made
          a prima facie showing that the testimony of Vazquez,
          a jailhouse informant, was reliable under § 54-86p.
             In February, 2021, Vazquez sent a letter to the state’s
          attorney’s office offering to provide information regarding the defendant if the state would ‘‘help’’ him. Vazquez
          sent the letter while incarcerated and after having been
          sentenced to fifteen years of imprisonment for multiple
          felony counts. The state subsequently contacted Vazquez to gather more information and then decided to
          call him as a witness at the defendant’s trial. Once the
          defendant learned that the state would present Vazquez
          as a witness, the defendant requested a reliability hearing pursuant to § 54-86p and moved to exclude Vazquez’
          testimony on the ground that it was unreliable under
          the statutory factors.
             Based on Vazquez’ testimony at the reliability hearing,
          the trial court found the following facts. ‘‘[T]he defendant was a cellmate . . . [with] Vazquez’’ and was
          ‘‘housed in the same unit or pod at Corrigan’’ during
          the ‘‘late summer, early fall of 2019,’’ although Vazquez
          later stated that he was not certain of the year. Vazquez

                             State v. Jacques

       had not heard Chadwick’s name prior to speaking with
       the defendant. Vazquez spent time with the defendant
       while they were in the same unit, where ‘‘the defendant
       admitted to him that he killed . . . Chadwick.’’ The
       defendant also told Vazquez that the state found ‘‘blood
       on his shoelaces or sneakers, that he tried to clean up
       some blood with a mop . . . that . . . he had put a
       cell phone in a wall in the bathroom and that the police
       said that they located it by pinging a location of the
       phone.’’ Vazquez also testified that the defendant told
       him that he had removed the SIM card from Chadwick’s
       cell phone to evade police detection and that another
       person named ‘‘P.K.’’ was present the night of the
       incident.
          The trial court further found that Vazquez had contacted the state’s attorney’s office voluntarily. He did
       not speak with ‘‘the police department or the state’s
       attorney’s office prior to writing the letter.’’ The court
       noted that Vazquez had never testified as an informant
       but had contacted authorities on other matters in the
       past, and he is an official ‘‘ ‘source of information’ for
       the Department of Correction . . . .’’ The court
       explained that ‘‘Vazquez receive[d] no benefit for being
       a source of information’’ other than ‘‘picking a cellmate.’’ The court acknowledged that, although Vazquez
       hoped to receive a reduced sentence in exchange for
       his testimony, ‘‘[n]o promises ha[d] been made to Vazquez in exchange for his testimony . . . .’’
         During the reliability hearing, the defendant chose
       not to testify or present witnesses after Vazquez’ testimony. The trial court nevertheless gave the defendant
       an opportunity to submit a supplemental brief to further
       address the admissibility of Vazquez’ testimony. In his
       memorandum of law in support of his motion to exclude
       Vazquez’ testimony, the defendant claimed that Vazquez’ testimony was not reliable and, accordingly, was
       inadmissible pursuant to § 54-86p. He primarily argued
Page 42                    CONNECTICUT LAW JOURNAL                         0, 0




          44                            ,0                  0 Conn. 1
                                  State v. Jacques

          that the information Vazquez provided was vague and
          already public knowledge. He also argued that the
          Department of Correction’s records indicated that the
          defendant and Vazquez did not overlap as prisoners at
          Corrigan during the summer of 2019, when the defendant allegedly confessed to Vazquez.

              The trial court denied the defendant’s motion to
          exclude Vazquez’ testimony, finding that it was reliable.
          The court stated that it had considered each factor
          set forth in § 54-86p and emphasized several specific
          factual findings to support its finding of reliability. First,
          the court noted that Vazquez reached out to the state
          ‘‘without having first been contacted by authorities
          . . . .’’ Second, the court found it significant that the
          information that Vazquez provided was ‘‘consistent with
          the investigation and corroborated other key evidence.’’
          In particular, the court emphasized that Vazquez mentioned that the defendant had told him that Chadwick’s
          cell phone was missing a ‘‘SIM card,’’ reasoning that
          this was likely not public information. Third, the court
          explained that Vazquez provided the information ‘‘without a witness’ cooperation agreement or any other benefit or promise provided in exchange for his testimony
          . . . .’’ Fourth, the court noted that the statements were
          obtained when the defendant and Vazquez were imprisoned in the same unit at Corrigan, even though Vazquez
          was ‘‘vague’’ about the ‘‘specific date(s) . . . .’’ Finally,
          the court was not made aware of an instance in which
          Vazquez had recanted proposed testimony or provided
          ‘‘jailhouse testimony against other defendants.’’ Accordingly, the trial court concluded that, ‘‘[i]n accordance
          with the testimony and exhibits submitted at the hearing, the consideration of [the defendant’s] memorandum [of law in support of his motion], and the statutory
          factors set forth in [General Statutes] §§ 54-86o and 54-
          86p, the court finds that the state has met its burden

       of proving the reliability of . . . Vazquez’ testimony
       and makes a threshold determination of reliability.’’
         The defendant claims that the trial court abused its
       discretion because it was unreasonable for the court
       to find that Vazquez’ testimony was reliable under § 54-
       86p. The defendant primarily argues that Vazquez provided vague information about details that were already
       public knowledge, inaccurate information about the
       SIM card, and that the trial court ignored that Vazquez
       had a strong incentive to testify against the defendant.17
       The state disagrees, arguing that the defendant failed
       to show a clear abuse of discretion and that the trial
       court acted reasonably in making its threshold determination of reliability. We agree with the state.
          It is well established that we will overturn a ‘‘trial
       court’s ruling on evidentiary matters . . . only upon a
       showing of a clear abuse of the court’s discretion.’’

             The defendant also argues in his reply brief that ‘‘the trial court failed
       to give adequate consideration to the factors that weighed against the reliability of Vazquez’ testimony . . . .’’ Although not explicitly argued, the defendant appears to argue that, because the trial court did not analyze each
       factor individually, it did not adequately consider them. Rather than set
       forth its analysis factor by factor, the trial court generally concluded that,
       ‘‘[a]fter careful consideration of the factors set forth in the statute, the court
       hereby finds that the state’’ met its burden under § 54-86p. The trial court’s
       analysis was not improper in this respect. Neither § 54-86p nor our case
       law requires the trial court to expressly discuss each § 54-86p factor individually. See General Statutes § 54-86p (a) (providing that trial courts ‘‘may
       consider the [enumerated] factors’’ (emphasis added)); State v. Bember, 
349 Conn. 417
, 443, 
316 A.3d 297
 (2024) (§ 54-86p ‘‘does not provide that any
       one of the enumerated factors is dispositive or that any are mandatory
       considerations’’). Rather, it is sufficient that the trial court considered the
       statutory factors. Absent evidence to the contrary, we ‘‘[presume] that the
       trial court properly applied the law’’; Dur-A-Flex, Inc. v. Dy, 
349 Conn. 513
, 533 n.6, 
321 A.3d 295
 (2024); especially in light of the court’s express
       acknowledgment that it carefully considered ‘‘the factors set forth in the
       statute . . . .’’

          trial court’s rulings, considering only whether the court

          Annulli, 
309 Conn. 482
, 491, 
71 A.3d 530
 (2013). ‘‘The
          issue, therefore, is not whether we would reach the
          same conclusion in the exercise of our own judgment,
          but only whether the trial court acted reasonably.’’ State
          v. Deleon, 
230 Conn. 351, 363
, 
645 A.2d 518
 (1994).
             The legislature has set forth a nonexhaustive list of
          factors that the trial court ‘‘may consider’’ when making
          a prima facie determination that a jailhouse informant’s
          testimony is reliable. General Statutes § 54-86p (a).
          These factors include ‘‘(1) [t]he extent to which the
          . . . testimony is confirmed by other evidence; (2) [t]he
          specificity of the testimony; (3) [t]he extent to which
          the testimony contains details known only by the perpetrator of the alleged offense; (4) [t]he extent to which
          the details of the testimony could be obtained from a
          source other than the defendant; and (5) [t]he circumstances under which the jailhouse witness initially provided information supporting such testimony to . . .
          [the] [p]olice . . . including whether the jailhouse witness was responding to a leading question.’’ General
          Statutes § 54-86p (a). ‘‘Importantly, the statute does not
          provide that any one of the enumerated factors is dispositive or that any are mandatory considerations.’’
          State v. Bember, 
349 Conn. 417
, 443, 
316 A.3d 297
 (2024).
             When considering the factors enumerated in § 54-86p
          (a), a court can consider ‘‘information . . . disclosed
          pursuant to . . . subsection (a) of section 54-86o
          . . . .’’ General Statutes § 54-86p (a). This includes (1)
          information about a jailhouse witness’ criminal history,
          (2) the existence of a jailhouse witness cooperation
          agreement, (3) details about ‘‘any statement allegedly
          given by the defendant to a jailhouse witness,’’ (4)
          whether the witness has previously ‘‘recanted any testimony subject to the disclosure,’’ and (5) ‘‘[i]nformation
          concerning any other criminal prosecution in which the

                              State v. Jacques

       jailhouse witness testified, or offered to testify . . . .’’
       General Statutes § 54-86o (a).
          Here, the trial court reasonably concluded that, consistent with § 54-86p (a), independent evidence corroborated specific details of Vazquez’ testimony. Specifically,
       Vazquez testified that the defendant told him that the
       police had found blood on his shoes or shoelaces and
       a mop at the crime scene, and that the defendant sought
       to remove the SIM card to prevent the police from
       tracking the cell phone’s location. Police testimony and
       exhibits introduced at trial confirmed these details. The
       details were specific, and it is unlikely that a source
       other than the defendant and the police would have
       known them.
          The defendant unpersuasively challenges the reasonableness of these findings. In his brief, the defendant
       primarily emphasizes that all the details, besides the
       SIM card, were publicly available, in which case, it
       is immaterial that they were corroborated. Nothing in
       Vazquez’ testimony or the record, however, supports a
       conclusion that the other facts were publicly available.
       Indeed, the defendant did not present evidence that
       established that these details were publicly available
       or that Vazquez had access to that information while
       incarcerated. See, e.g., State v. Little, 
194 Conn. 665, 673
, 
485 A.2d 913
 (1984) (‘‘[a]ny inferences drawn [by
       the trier of fact] must be rational and founded upon
       the evidence’’).
         The defendant further argues that the details about
       the SIM card are factually incorrect because the police
       report indicated that the ‘‘SD card,’’ not the SIM card,
       was missing from Chadwick’s cell phone. The defendant
       contends that the trial court ‘‘presumably relied on this
       information when making its finding[s] . . . .’’ The trial
       court, however, reasonably could have inferred that the
       defendant mistakenly thought he had removed the SIM
Page 46                   CONNECTICUT LAW JOURNAL                      0, 0

          card but actually had removed the SD card. See, e.g.,
          State v. Mark T., supra, 
339 Conn. 232
. The trial court
          also reasonably could have inferred that the defendant
          thought that the SD card was the SIM card. In either
          case, the trial court could have reasonably concluded
          that this information supported its conclusion that Vazquez’ testimony was reliable.

             The defendant also argues that the trial court could
          not have reasonably concluded that the circumstances
          under which Vazquez provided the information to the
          state’s attorney’s office were reliable. He claims that in
          situations, as here, in which a jailhouse informant writes
          a letter explicitly offering to provide information about
          the defendant in exchange for the state’s ‘‘help’’ shortly
          after receiving a fifteen year sentence, a trial court
          cannot conclude that the informant’s testimony is reliable. We have emphasized, however, that ‘‘the expectation of a [r]eward for testifying is a systemic reality
          . . . even [when] the informant has not received an
          explicit promise of a reward.’’ (Citation omitted; internal quotation marks omitted.) State v. Arroyo,

 (highlighting that ‘‘several commentators have
          pointed out that jailhouse informants frequently have
          motives to testify falsely that may have nothing to do
          with the expectation of receiving benefits from the government’’). Furthermore, the trial court considered
          other aspects of Vazquez’ testimony and information
          provided under § 54-86o. Specifically, the trial court
          highlighted that Vazquez’ initial letter to the state was
          unprompted, that he testified without a witness cooperation agreement, and that he had not otherwise
          recanted proposed testimony in other criminal proceedings or previously testified as a jailhouse informant.
          Based on this information, the court could have reason-
0, 0                   CONNECTICUT LAW JOURNAL                       Page 47

       ably concluded that the circumstances under which
       Vazquez’ statement was given were reliable.
          Even if this court came out differently on the question
       of whether the circumstances under which Vazquez
       gave his statement supported a finding of reliability,
       we cannot, on this record, conclude that the trial court’s
       overall finding of reliability was a clear abuse of discretion. Whether the circumstances under which Vazquez
       initially provided information to the state support a
       finding of reliability implicates one statutory factor. But
       no single factor is ‘‘dispositive or . . . mandatory
       . . . .’’ State v. Bember, supra, 
349 Conn. 443
. Because
       the trial court’s factual findings were otherwise reasonable, we conclude that the trial court did not abuse its
       discretion in finding that the state had made a prima
       facie showing that Vazquez’ testimony was reliable and,
       therefore, admissible at trial after consideration of all
       of the factors enumerated in §§ 54-86o and 54-86p.
         The judgment is affirmed.
         In this opinion the other justices concurred.
