                                                 OPINION

                By the Court, BELL, J.:

                             Tragically, sixteen-year-old Gabrielle (Britney) Ujlaky lost her
                life in March 2020, the victim of homicide. A jury convicted appellant Bryce
                Edward Dickey of sexually assaulting and murdering Britney. Dickey now
                asserts his criminal convictions should be reversed, in part because the
                court permitted Dickey's ex-girlfriend to testify at trial that Dickey choked
                her during otherwise consensual sex. Dickey also raises concerns regarding
                testimony of expert witnesses.
                             Although we conclude the district court erred in admitting other
                act evidence for identification purposes, in admitting highly prejudicial
                evidence regarding the timing of one of the other acts, and in failing to
                narrowly tailor its subsequent limiting instruction regarding the testimony,
                we conclude that these errors are harmless.      We take this opportunity,
                however, to clarify that the balancing test for propensity evidence of other
                sexual offenses admissible under NRS 48.045(3) does not apply to the
                admission of other act evidence concerning identity or intent under NRS

                48.045(2).   Likewise, the failure of the district court to make a proper
                finding regarding an expert witness also constituted harmless error. We
                conclude that the district court did not abuse its discretion by admitting
                expert testimony about rigor mortis or by denying a motion for a mistrial.
                Additionally, sufficient evidence supported the sexual assault conviction.
                Accordingly, we affirm Dickey's convictions.
                                  FACTS AND PROCEDURAL HISTORY
                             On March 8, 2020, Britney Ujlaky's family reported her

                missing. According to the•family, Bryce Dickey gave Britney a ride, but she
                never arrived home. Dickey initially claimed he dropped Britney off at

                    Spring Creek High School and witnessed Britney leave with a rnan in a
                    green truck.
                                Three days after she disappeared, volunteers discovered

                    Britney's body in a remote area outside Elko. Britney was partially clothed,
                    and her body had been wrapped in a blue tarp. Autopsy results revealed
                    Britney died from a stab wound to her neck and strangulation, possibly with
                    a cord of some kind.
                                Officers collected evidence from the scene, including a used
                    condom in a nearby bush that matched a box of condoms from Dickey's
                    truck. The found condom contained DNA evidence: Dickey's DNA on the
                    inside and Britney's on the outside. Dickey's DNA was also found on swabs
                    taken from Britney's neck and fingernails, as well as on chewing tobacco

                    found near Britney's body.
                                Dickey initially denied having any sexual encounter with
                    Britney. Dickey's story later shifted. Dickey told police that he and Britney
                    engaged in consensual oral sex while Dickey was wearing a condom. During

                    that interview, Dickey claimed after the sexual encounter he dropped
                    Britney off near a trailer park with a man named Chaz Randall.
                                The State charged Dickey with open murder, including first-degree murder with the use of a deadly weapon, and sexual assault with the
                    use of a deadly weapon. Dickey entered a not guilty plea, and the case
                    proceeded to trial.
                                Prior to trial, the State filed a notice of intent to call expert
                    witnesses forensic pathologist Dr. Julie Schrader and intelligence analyst
                    Mike Soto. The notice provided, "Dr. Schrader is expected to testify and
                    offer opinions in the area of forensic pathology and will testify regarding the
                    autopsy of [the victim], her cause(s) of death, and all observations and

                conclusions underlying those opinions." The State attached Dr. Schrader's
                forensic report to the notice. The State's notice also indicated that Soto
                would "testify and offer his opinion about [Dickey's] and Britney's
                geolocation data derived from Snapchat," attaching a report from the Rocky
                Mountain Information Network overlaying data from the social media
                company Snapchat onto a map. That data consisted of latitudes, longitudes,
                and timestamps from Britney's and Dickey's Snapchat accounts.
                            At trial, the State presented testimony from Dr. Schrader
                regarding Britney's autopsy, the cause of Britney's death, and rigor mortis.
                The State also called Soto to testify regarding the geolocation data from
                Snapchat, placing Dickey and Britney at the location where Britney's body
                was eventually discovered. Additional evidence presented at trial included
                surveillance footage from an apartrnent complex that showed Dickey's truck
                drove past Britney's high school without stopping on the day Britney was
                reported missing and testimony from Dickey's ex-girlfriend about four
                instances when Dickey choked the ex-girlfriend without consent while the
                couple engaged in otherwise consensual sex.        Dickey choked the ex-girlfriend on multiple occasions after she expressly told him not to. The
                last, and most violent, of these incidents occurred on the night of a
                candlelight vigil in Britney's honor.
                            Before her testimony, the ex-girlfriend entered the courtroom
                in violation of the exclusionary rule and watched a small portion of
                Detective Nicholas Stake's testimony. As a result, Dickey requested the
                court preclude the ex-girlfriend's testimony or declare a mistrial. Outside
                the presence of the jury, the ex-girlfriend testified she was unaware
                witnesses were excluded from entering the courtroom. The ex-girlfriend
                heard about five minutes of Detective Stake's testimony regarding weather

                conditions when Britney's body was discovered. The courtroom bailiff also
                testified, corroborating the ex-girlfriend's testimony. The district court
                admonished the State to make witnesses aware of the exclusionary rule but
                ultimately denied Dickey's motion for a mistrial and allowed the ex-girlfriend to testify.
                             At the close of trial, the jury found Dickey guilty of first-degree
                murder with the use of a deadly weapon and sexual assault with the use of
                a deadly weapon. Dickey was sentenced to life with the possibility of parole
                after a minimum of 46 years. Dickey now appeals.
                                             DISCUSSION
                             Dickey appeals on numerous grounds, including that the
                district court (1) erred in admitting evidence of other acts between Dickey
                and the ex-girlfriend, (2) gave incorrect jury instructions with respect to the
                admitted other acts testimony, (3) erred in denying Dickey's motion for a
                mistrial when the ex-girlfriend violated the exclusionary rule, and
                (4) admitted deficient expert testimony. Dickey also claims (5) insufficient
                evidence exists to support his conviction for sexual assault and
                (6) cumulative error warrants reversal. We disagree that any error present
                is reversible and affirm the district court's judgment of conviction.
                The district court erred in analyzing other act evidence
                             Dickey contends the district court abused its discretion by
                admitting the ex-girlfriend's testimony that Dickey choked her without
                consent during otherwise consensual sex. Dickey asserts the ex-girlfriend's
                testimony constituted impermissible character evidence under NRS
                48.045(1). Alternatively, Dickey asks this court to find the district court
                erred in finding the ex-girlfriend's testimony was not substantially more
                prejudicial than probative. This court reviews the admission of evidence for

                an abuse of discretion. See Mclellan v. State, 
124 Nev. 263, 267
, 
182 P.3d 106, 109
 (2008).
                            The district court granted the State's motion to admit the ex-girlfriend's testimony under NRS 48.045(2), which allows other acts to be
                admitted for certain nonpropensity purposes. Other act evidence carries a
                presumption of inadmissibility. Ledbetter v. State, 
122 Nev. 252, 259
, 
129 P.3d 671, 677
 (2006). Before the admission of other act evidence, a court
                must hold an evidentiary hearing outside the presence of the jury. Based
                on the evidence presented, the court may find the presumption rebutted and
                admit other act evidence if the act is (1) relevant, (2) proven by clear and
                convincing evidence, and (3) not substantially more prejudicial than
                probative. Petrocelli v. State, 
101 Nev. 46, 51
, 
692 P.2d 503, 507
 (1985); see
                also Ledbetter, 
122 Nev. at 259
, 
129 P.3d at 677
 (applying the same analysis
                as in Petrocelli, citing to Tinch v. State, 
113 Nev. 1170, 1176
, 
946 P.2d 1061, 1064-65
 (1997)). If the Petrocelli requirements are met, the evidence may
                be admitted for limited nonpropensity purposes as found by the court. Here,
                after an evidentiary hearing, the district court determined the ex-girlfriend's testimony was properly offered to prove Dickey's identity and
                intent.
                            We cannot say the district court properly applied Petrocelli.
                The district court erred in admitting the evidence to prove identity, in
                applying the Franks test to determine whether the evidence was more
                prejudicial than probative, and in allowing the admission of prejudicial
                evidence of low probative value. See Franks v. State, 
135 Nev. 1
, 6, 
432 P.3d 752, 756
 (2019). Nevertheless, because we conclude the ex-girlfriend's
                testimony was admissible under a Petrocelli analysis to prove intent, we

                affirm the district court's decision to admit the evidence and deern the errors
                harmless given the overwhelming evidence of guilt.
                      Under Petrocelli, the ex-girlfriend's testimony was properly admitted
                      to prove Dickey's intent but not to prove his identity
                            NRS 48.045(2) allows litigants to present evidence of other acts
                when offered for certain limited nonpropensity purposes including "proof of
                motive, opportunity, intent, preparation, plan, knowledge, identity, or
                absence of mistake or accident."       The State moved to admit the ex-girlfriend's testimony for the limited purposes of proving identity and
                intent.   Notably, the State did not request to admit the evidence for
                propensity under NRS 48.045(3).
                            Identity
                            First, we address whether the ex-girlfriend's testimony could be
                properly admitted to prove identity under NRS 48.045(2). For identity
                purposes, other acts have probative value "only to the extent that
                [d]istinctive "common marks" give logical force to the inference of identity.
                If the inference is weak, the probative value is likewise weak, and the
                court's discretion should be exercised in favor of exclusion." Mayes v. State,
                
95 Nev. 140, 142
, 
591 P.2d 250, 252
 (1979) (quoting People v. Banks, 
465 P.2d 263, 271
 (Cal. 1970)).
                            Here, the sole act of choking during sex does not qualify as a
                distinctive common mark creating a logical inference that a separate
                instance of choking was done by the same person. Discrepancies between
                Dickey's conduct towards the ex-girlfriend and the strangulation of Britney
                further undercut any inference regarding identity: Britney's autopsy
                suggested she was strangled with a ligature; the ex-girlfriend testified
                Dickey choked her with his hand. Because the ex-girlfriend's testimony is

                          not reasonably probative of the identity of Britney's attacker, her testimony
                          was not properly admitted for that purpose.
                                      Intent
                                      We now consider whether the evidence was properly admitted
                          to prove intent. At trial, Dickey's sole defense to the sexual assault charge
                          was consent. Consequently, Dickey placed the element of intent at issue.
                          As we held in Williarns v. State, "[t]he crucial question in determining if a
                          sexual assault has occurred is whether the act [was] committed without the
                          consent of the victim, and the intent of the accused is relevant to the issue
                          of consent or [the] lack thereof."

                          (internal citation omitted). A defendant's assertion of consent in a sexual
                          assault case "place [s] in issue [intent as] a necessary element of the offense,"
                          which opens the door to the admission of other act evidence as rebuttal. Id.;

                                      The ex-girlfriend's testimony is relevant and probative of intent
                          as it presents evidence of Dickey's increasing violence around sex and intent
                          to engage in the choking activity in the face of explicit nonconsent. Just as
                          in the Williams case evidence of "sexual misconduct with other persons was
                          admitted as being relevant to prove his intent to have intercourse with the
                          victim without her consent," evidence of Dickey's willingness to choke a
                          sexual partner without consent is relevant to prove his intent to strangle
                          Britney without her consent as part of their sexual interaction. Williams,

                    it would be without the evidence"). The question of admission to prove
                    intent is a closer one than in Williams. Still, here as in Williams, the State
                    offered the ex-girlfriend's testimony not for propensity purposes, but to
                    demonstrate that choking a woman without consent during sex was an
                    established element of Dickey's sexual proclivities and supported a finding
                    that he intended to ignore Britney's lack of consent to choking during sex.
                    Therefore, we cannot say the district court abused its discretion in
                    admitting the ex-girlfriend's testimony as at least minimally probative of
                    intent.
                                The ex-girlfriend's testimony sufficiently established the other
                    act by clear and convincing evidence. See Rose v. State, 
123 Nev. 194, 203
,

 (1992)) (the victim's testimony alone is sufficient to establish
                    guilt of sexual assault beyond a reasonable doubt, so long as the testimony
                    includes "some particularity regarding the incident"). The district court
                    found the ex-girlfriend's testimony credible, and we do not disturb this
                    determination. Mitchell v. State,

                    of witnesses" on appeal).
                                Finally, we examine whether the ex-girlfriend's testimony was
                    substantially more prejudicial than probative. See Petrocelli,

                    Petrocelli itself does not contain explicit factors to consider regarding the

                           that has elapsed between the crimes, the need for
                           the evidence, the efficacy of alternative proof, and
                           the degree to which the evidence probably will
                           rouse the jury to overmastering hostility."

477 P.3d 342
, 349 (2020) (quoting State v. Castro, 
756 P.2d 1033, 1036
 (Haw. 1988)) (analyzing admissibility under NRS
                48.045(2)).
                              Following the Randolph factors here, first, the ex-girlfriend
                testified under oath regarding the instances of choking. Nothing in the
                record suggests that her testimony inaccurately described the prior acts.
                Second, Dickey's choking of the ex-girlfriend was arguably similar to the
                offense against Britney, as both involved elements of choking along with
                sexual contact. Yet, we acknowledge that the acts against the ex-girlfriend
                and Britney are not identical. Britney was likely strangled with an object,
                while the ex-girlfriend testified Dickey choked her with his hand.
                              Third, the ex-girlfriend testified that the four instances of
                choking occurred within the year preceding Dickey's arrest. As to the fourth
                and fifth factors, Britney's consent, or lack of consent, to sexual contact with
                Dickey is an essential question in this case. No other testimony, save
                Dickey's own, provided any direct evidence towards the issue of consent.
                The ex-girlfriend's testimony presented evidence of Dickey's past violence
                around sex, including intent to engage in the choking activity without
                consent.
                              When considering the sixth and final factor, we are compelled
                to make further distinctions regarding the ex-girlfriend's testimony. The
                first three instances of choking to which the ex-girlfriend testified would
                not, on their own, support a finding of undue prejudice. Accordingly, under

                Petrocelli, the ex-girlfriend's testimony regarding the first three instances
                of choking was properly adrnitted on this issue of intent.
                            We must. take note, though, of the particularly inflammatory
                testimony concerning the last instance of choking, which occurred on the
                night of a candlelight vigil held to honor Britney. Pointing out the timing
                of this particular incident was highly prejudicial. Also, given the admission
                of the other act testimony for intent, the timing of the event possesses
                virtually no probative value. As a result, the district court erred in allowing
                testimony regarding the specific timing of this incident. Nonetheless, the
                weight of independent, cumulative evidence against Dickey renders this
                error harmless. See Tavares v. State, 
117 Nev. 725, 732
, 
30 P.3d 1128, 1132
                (2001) (holding an error is harmless unless it has a "substantial and
                injurious effect or influence in determining the jury's verdict" (quoting
                Kotteakos v. United States, 
328 U.S. 750, 776
 (1946))).
                            The district court also improperly applied the balancing test
                outlined in Franks, 135 Nev. at 6, 
432 P.3d at 756
, to make its prejudice
                findings. Franks interpreted NRS 48.045(3), which allows evidence of other
                sexual offenses to be admitted for propensity purposes in "a criminal
                prosecution for a sexual offense."         At no point did the State seek
                admissibility under NRS 48.045(3), and the evidence was not admitted for
                propensity purposes. Thus, the district court improperly applied the Franks
                test.
                            Today, we make clear that Franks and Petrocelli are not
                interchangeable standards. Parties have an obligation to clearly identify
                the exception to the general principle of inadmissible character evidence
                under which they are seeking admission.         While we recognize that, in
                practice, the inquiries the district courts must undertake are relatively

                similar, the blended application of two distinct statutory schemes collapses
                the broader, nonpropensity analysis of Petrocelli and the limited-scope
                propensity analysis of Franks. This confusion complicates appellate review
                and risks the improper use of NRS 48.045(3) beyond the narrow scope
                intended by the Legislature.
                             The Franks test for determining prejudice when admitting a
                prior sexual offense for the purpose of propensity contains a slightly
                narrower and more stringent test than the one used to determine the
                prejudicial impact of other act evidence admitted in nonpropensity contexts.
                See United States v. LeMay, 
260 F.3d 1018, 1027
 (9th Cir. 2001) ("Because
                of the inherent strength of the evidence [of prior sexual offenses] . . . a court
                should pay careful attention to both the significant probative value and the
                strong prejudicial qualities of that evidence." (quoting Doe v. Glanzer, 
232 F.3d 1258, 1268
 (9th Cir. 2000))); see also Alfaro v. State, 
139 Nev., Adv. Op. 24
, 
534 P.3d 138
, 150-51 (2023) (applying the Franks test). In this regard,
                any error would tend to help, rather than harm, Dickey. Thus, the error is
                harmless.
                            We likewise determine the district court's error in admitting

                the ex-girlfriend's testimony to prove identity was harmless given the
                quantity of evidence supporting the State's case against Dickey and its
                proper use to prove intent. See Fiegehen v. Stctte, 
121 Nev. 293, 296
, 
113 P.3d. 305, 307
 (2005) (finding harmless error where overwhelming evidence
                of guilt existed, including an identification and DNA evidence at the crime
                scene). The State's evidence at trial included DNA and geolocation data
                placing Dickey at the scene of the crime, inconsistent statements to police
                that could reasonably impact Dickey's credibility with the jury, and a used
                condom proving Dickey had sexual contact with Britney.

                The district court's errors in providing limiting jury instructions were
                harrnless
                            Dickey next contends that the district court erred by giving the
                jury an overly broad limiting instruction regarding the ex-girlfriend's
                testimony. The instruction failed to limit use of the other act evidence to
                establishing identity or intent—the only purposes for which the district
                court allowed the evidence. After admitting the ex-girlfriend's testimony
                for the limited purposes of identity and intent, the district court
                administered the following jury instruction:
                            Evidence has been received tending to show that
                            the defendant committed wrongs or acts other than
                            that for which he is on trial.
                            Such evidence was not received and may not be
                            considered by you to prove that he is a person of bad
                            character or that he has a disposition to commit
                            such crimes.
                            Such evidence was received and may be considered
                            by you only for the limited purpose of determining
                            if it tends to prove motive, opportunity, intent,
                            preparation, plan, knowledge, identity, absence of
                            mistake or accident, or a common scheme or plan.

                The district court offered this instruction once immediately prior to the ex-girlfriend's testimony and once at the close of trial.
                            When admitting evidence for limited purposes under NRS
                48.045(2), limiting instructions must instruct the jury to consider only those
                purposes for which the evidence was actually admitted. Any instruction to
                consider purposes for which admission was not granted constitutes an error
                subject to NRS 178.598 harmless error review. Allred v. State,

                                       The district court erred by including all potential purposes
                           listed for admission of other act evidence under NRS 48.045(2), instead of
                           limiting its instruction to only the purposes for which the court found the
                           evidence admissible—identity and intent. Additionally, given the error in
                           admitting the evidence for purposes of identity, a proper limiting
                           instruction in this case should have informed the jury that it could consider
                           the other act evidence for the purpose of intent only.
                                       As a result, we rnust consider whether such an error is
                           harmless. We consider whether the district court's instruction to consider
                           the ex-girlfriend's testimony for the purposes of intent, motive, opportunity,

                           preparation, plan, knowledge, absence of mistake or accident, and common
                           scheme or plan had a substantial and injurious impact on the verdict. We
                           conclude it did not.
                                       Substantial, independent evidence exists to support Dickey's
                           convictions. When considering the ex-girlfriend's testimony, we cannot say
                           that instructing the jury on all potential purposes for the admission of other
                           acts under NRS 48.045(2) altered the outcome of this case. Accordingly, we
                           hold the error in the provided jury instructions harmless.
                           The district court did not abuse its discretion in declining to declare a
                           mistrial based on a violation of the exclusionary rule
                                       "The decision to grant a mistrial is within the sound discretion
                           of the trial court and will not be overturned absent an abuse of discretion."

                excluded so that they cannot hear the testimony of other witnesses"). On
                learning of this violation, the district court adrnonished the State and
                permitted examination of the ex-girlfriend outside the presence of the jury.
                This examination revealed minimal basis for harm, as the testimony the ex-girlfriend witnessed was irrelevant to her own. The district court took
                remedial measures to avoid prejudice from the ex-girlfriend's violation and
                found no bad faith existed on the part of the State. The violation could not
                have impacted the ex-girlfriend's unrelated testimony. Consequently, the
                district court did not abuse its discretion by denying Dickey's motion for a
                mistrial.
                             Any other alleged violations of the exclusionary rule were either
                not raised before the district court or not adequately briefed before this
                court, and so we decline to reach them. Maresca v. State,

                The district court properly admitted Dr. Schrader's expert testimony; it erred
                when it failed to conduct a Hallmark analysis on a proposed expert witness,
                but this error was harmless
                             Dickey next argues the district court abused its discretion when

                State's NRS 174.234 notice procedures were insufficient, and (2) Soto's
                expert testimony about geolocation data placing Dickey with Britney at the
                time and place of her death when he was not qualified to offer expert
                testimony.

                NRS 174.234(2) (held unconstitutional on other grounds in Grey v. State,
                
124 Nev. 110, 118
, 
178 P.3d 154, 160
 (2008)). This notice must include "[a]

                brief statement regarding the subject matter on which the expert witness is
                expected to testify and the substance of the testimony." NRS 174.234(2)(a).
                The State served timely notice of its intent to use Dr. Schrader as an expert,
                including a copy of Dr. Schrader's autopsy report and a statement

                announcing the State's intent to examine Dr. Schrader regarding the
                contents of the attached report.    Dickey did not object to Dr. Schrader's
                testimony during trial and therefore failed to preserve the alleged error for
                appeal.    Jeremias v. State, 
134 Nev. 46
, 50, 
412 P.3d 43, 48
 (2018).
                Additionally, given that the attached autopsy report discussed rigor mortis,
                the State provided adequate notice to the defense regarding the potential
                for this testimony. The district court did not err in allowing Dr. Schrader's
                testimony when Dickey failed to object, and the State provided adequate,
                timely notice under NRS 174.234.
                      Soto's opinion testirnony about geolocation data
                            Dickey also challenges the qualification of Soto as an expert
                witness.    Dickey argues the district court erred in admitting Soto's
                testimony over Dickey's objection, implying that the district court was
                required to qualify Soto as an expert under Hallmark v. Eldridge. Dickey
                argued that Soto failed to employ a reliable methodology per NRS 50.275.

                qualified in an area of specialized knowledge, (2) use that knowledge to
                assist the trier of fact, and (3) limit their testimony to matters within the
                scope of that knowledge).      The district court made no such findings,
                concluding only that Soto's testimony was a product of reliable methodology.

                                   Here, our ability to review the district court's action is
                       complicated by the district court's unclear response to Dickey's objection.
                       By finding Soto's testimony was the product of reliable methodology, the
                       district court seems to understand its ruling to allow Soto to offer expert
                       testimony despite the State's assertion Soto need not be so qualified. See

 (requiring district courts qualifying experts to
                       consider factors including whether the testimony is a "product of reliable
                       methodology"). To the extent the district court's action qualified an_ expert
                       witness, we review that decision for abuse of discretion. 
Id. at 498
, 
189 P.3d at 650
.
                                   First, we make clear that when a party objects to the
                       qualifications of a witness on the basis that the witness is not qualified to
                       offer the proffered opinion under Hallmark, the district court is required to
                       either conduct a full Hallmark analysis or to make clear expert qualification
                       is not necessary. Because Dickey properly raised an objection based on
                       Soto's qualifications to testify on the geolocation data, and because it
                       appears the district court dispatched this objection through an incomplete
                       Hallmark analysis, we conclude the district court erred in failing to conduct
                       a complete Hallmark analysis regarding Soto's testimony.
                                   Nevertheless, we conclude the error was harmless, because
                       under our prior caselaw, Soto's testimony did not require specialized
                       knowledge. See NRS 178.598 ("Any error, defect, irregularity or variance
                       which does not affect substantial rights shall be disregarded."). Soto plotted
                       geolocation data on a map and adjusted the data to the local time. In
                       Burnside v. State, a detective was similarly permitted to testify to a map he
                       created from cell phone location data without being qualified as an expert.

                the detective's testimony were not based on specialized knowledge." 
Id.
                Soto's testimony is indistinguishable from the testimony in Burnside. In
                both cases, the witness plotted data obtained from another source onto a

                map. Thus, the district court did not abuse its discretion because Soto's
                testimony was admissible as lay testimony, without requiring an expertwitness analysis.
                Sufficient evidence existed for a rational jury to convict Dickey of sexual
                assault
                            Dickey asserts that insufficient evidence supports the sexual
                assault conviction.   We "will not disturb a judgment of conviction in a
                criminal case on the basis of insufficiency of the evidence so long as the jury
                verdict is supported by substantial evidence." Mitchell v. State, 
105 Nev. 735, 737
, 
782 P.2d 1340, 1342
 (1989). "In determining the sufficiency of the
                evidence below, the critical question is whether, after viewing the evidence
                in the light most favorable to the prosecution, any rational trier of fact could
                have found the essential elements of the crime beyond a reasonable doubt."
                Mejia v. State, 
122 Nev. 487, 492
, 
134 P.3d 722, 725
 (2006) (internal
                quotation marks omitted).
                            Dickey argues a rational jury could not have found forced
                penetration because the autopsy reported a lack of genital trauma. Sexual
                assault occurs when one person "[s]ubjects another person to sexual
                penetration.     against the will of the victim." NRS 200.366(1)(a). The
                plain language of the statute neither requires force nor physical injury.
                            The State presented substantial circumstantial evidence
                sufficient to support the jury's guilty verdict of sexual assault. See Wilkins

                v. State, 
96 Nev. 367, 374
, 
609 P.2d 309, 313
 (1980) (allowing a jury to rely
                on circumstantial evidence to support a verdict). Dr. Schrader testified a
                sexual assault may occur with no physical findings whatsoever and lack of

                      injury does not equate with consent. Dickey admitted to having oral sex
                      with Britney, despite first denying any sexual contact and claiming Britney
                      was like a little sister. Geolocation data placed Dickey and Britney together
                      at the location where Britney's body was later discovered, and a condom
                      with both their DNA profiles was found at the scene. Finally, Britney's body
                      was found in a state of undress. The jury could have reasonably relied on
                      this evidence to conclude, as the State argued in its closing, that Britney
                      was given a choice between death and performing oral sex on Dickey, after
                      which Dickey killed her to prevent her from speaking out. See Mitchell, 
105 Nev. at 737
, 
782 P.2d at 1342
 (upholding a jury verdict of sexual assault
                      when there was no evidence of physical trauma to the victim's genitalia, but
                      the victim was found in a remote area and in a state of undress). Likewise,
                      the jury here could have rejected Dickey's assertion of consensual sex given
                      the circumstances of Britney's death and Dickey's changing versions of the
                      events.
                                  The facts presented at trial provided substantial evidence for a
                      reasonable jury to find Dickey guilty of sexual assault under Nevada law.
                      Accordingly, sufficient evidence existed to convict Dickey on this count.
                      Cumulative error does not warrant rever,sal
                                  Lastly, Dickey claims the cumulative errors in his case warrant
                      reversal. A defendant's right to a fair trial may be violated by the
                      cumulative effect of errors even when any one error, individually, is
                      harmless. See Hernandez u. State,

, 
50 P.3d 1100, 1115
                      (2002). When evaluating a claim of cumulative error, relevant factors
                      include "(1) whether the issue of guilt is close, (2) the quantity and character
                      of the error, and (3) the gravity of the crime charged." Mulder v. State,

101 1947A
                            On this record we have found four instances of error that could
                have impacted Dickey's conviction: (1) the district court improperly
                admitted the ex-girlfriend's testimony for purposes of identity; (2) the
                district court improperly admitted the ex-girlfriend's testimony that Dickey
                choked her on the night of Britney's candlelight vigil; (3) the jury was given
                erroneous instructions to consider the ex-girlfriend's testimony, generally,
                for motive, opportunity, preparation, plan, knowledge, absence of mistake
                or accident, and common scheme or plan; and (4) the district court failed to
                engage in a full Hallmark analysis for Soto. We determined each of those
                errors harmless and there is nothing cumulative in the nature of those
                errors to warrant reversal. Here, despite the grave nature of the crime,
                evidence of guilt was overwhelming. Errors did not impugn the overall
                integrity of the trial and were not the by-product of any bad faith on the
                part of the State. We are not convinced the cumulative weight of these
                errors deprived Dickey of his constitutional right to a fair trial.
                                               CONCLUSION
                            Parties must make clear the specific bases for admission of
                other act evidence under Petrocelli and NRS 48.045(2). The court, after an
                evidentiary hearing, must determine whether any of those bases apply,
                being careful to analyze the foundation for each basis. Courts must take
                care not to mix the Franks and Petrocelli analyses, as the tests, instructions,
                and use of evidence differ for other act evidence and other sexual offense
                evidence. Any limiting instruction given regarding the admission of other
                act evidence must specify only the bases determined by the court.
                            A district court also must engage in a thorough Hallmark
                analysis, either in writing or on the record, when a party has challenged the
                qualifications of an expert.      Prior caselaw of this court supports a

                require expert testimony. Despite a few harmless errors by the trial court
                in these regards, the State presented overwhelming evidence to support the
                jury's conviction of Dickey for murder and sexual assault. Accordingly,
