¶1The defendant appeals from his convictions, after a bench trial in the Superior Court, of conspiracy to traffic in marijuana, G. L. c. 94C, § 40, and trafficking in marijuana in an amount more than one hurdred and less than two thousand pounds, G. L. c. 94C, § 32E(u)(2). We affirm.
¶2*50Factual background. A Massachusetts State trooper, working undercover as a United Parcel Service (UPS) driver, delivered four large boxes with a return address in Phoenix, Arizona, to Prestige Auto Detailing (Prestige) in Leominster. A number of State, local, and Federal officers were nearby, and an anticipatory search warrant had been obtained as part of a controlled delivery.
¶3Just before the delivery, another officer saw a pickup truck, driven by the defendant, with a passenger, Alberto Camacho-Flores, approach the front of the Prestige building, and park facing the building. He observed both men go inside. When the UPS truck drove up, the defendant left the building, entered his truck, and drove away. After entering a bay doorway to the building, and announcing the delivery to two men inside, the trooper asked where he should put the boxes. Camacho-Flores asked the other man, Pablo Oquendo, and Oquendo indicated they should be placed inside, along a wall. Camacho-Flores subsequently went out to the UPS truck with the trooper and signed for the delivery. When the UPS truck left, the two men stacked the boxes outside the bay door.
¶4Sufficiency of the evidence. Claiming that the Commonwealth failed to prove the knowledge element in both the conspiracy and the trafficking charges, the defendant argues that his motion for a required finding of not guilty should have been allowed at the close of the Commonwealth’s case. He relies on Commonwealth v. Aguiar, 370 Mass. 490, 499 (1976), which states: “In the absence of other evidence, possession of an unopened package, containing drugs, addressed to another and received through the mail moments before his arrest, would not warrant an inference beyond a reasonable doubt that a defendant possessed the drugs knowingly.” Here, however, the defendant was not merely the passive recipient of an unopened package. The appearance of the defendant and his passenger at Prestige, and their subsequent conduct, support a reasonable inference that they were expecting the UPS delivery. In driving away as the delivery was being made, and leaving Camacho-Flores behind, it reasonably may be inferred that the defendant sought to keep himself and his truck out of sight. Similarly, the boxes, signed for by Camacho-Flores, were placed inside until the UPS truck left. They then were moved outside, as if in anticipation of the defendant’s return. When the defendant returned, his backing of his truck toward the boxes was further indication of a plan to take them away. That neither the defendant nor Camacho-Flores appear to have had any connection with Prestige, and their quick removal of the boxes from that business, unopened, support the inference that they participated in a plan to use that address merely as an interim point of delivery. This evidence, coupled with the defendant’s “incredible” statement to the police concerning how he came to be present where the pack*52ages were delivered,
¶5Admissibility of the statement. Because the defendant’s statement was relied upon by the Commonwealth in obtaining the defendant’s conviction, we address his challenge to its admissibility. During direct examination of the trooper who took the statement, defense counsel asked the judge to determine if the defendant had been informed of his Miranda
¶6Contrary to assuming that the defendant was in custody when he was interrogated, as did the judge, we independently address the issue.
¶7In the separate hearing the defendant neither provided nor elicited any evidence that he was questioned in circumstances constituting coercion or custody. That failure of the defendant to meet his threshhold burden excused the Commonwealth from proving that Miranda warnings had been provided. Moreover, even if we take into account the evidence introduced at trial and outside of the hearing and view it in light of the established analytical framework, see Commonwealth v. Bryant, 390 Mass. 729, 737 (1984), we cannot say that sufficient evidence of *54custodial interrogation has been produced. Although some ten to fifteen local, State, and Federal police and other officers were in the general vicinity, and perhaps six or seven “converge[d]” on the three men at the building, no more than two officers were with the defendant when he was interrogated. There is no indication where the questioning took place, other than it occurred at the Prestige site, or how much time elapsed before the defendant signed a document setting forth the questions put to him and his responses. There is no evidence that the defendant was under arrest or was confined or handcuffed at the time of the interrogation or that the circumstances of the questioning were intimidating. The trooper testified that he spoke to the defendant in English, and had no problem understanding the defendant, who responded in English and was not reluctant to talk. The questions themselves, fairly read, are not accusatory or aggressive, and the defendant’s answers generally were in brief narrative form. Compare Commonwealth v. Borodine, 371 Mass. 1, 4-5 (1976), cert. denied, 429 U.S. 1049 (1977).
¶8Because we conclude the defendant did not meet his burden of showing custodial interrogation, we find it unnecessary to review the judge’s conclusion that “a full recitation of [the] Mirandawarnings were given.” See Commonwealth v. Bryant, 390 Mass. 729, 742 & n.15 (1984). Also, in light of our decision, we decline the defendant’s invitation to revisit Commonwealth v. Mitchell, 47 Mass. App. Ct. 178, 181 (1999), and Commonwealth v. Rendon-Alvarez, 48 Mass. App. Ct. 140, 141 (1999),
¶9Judgments affirmed.
¶10The boxes first came to the attention of local police at a UPS terminal in Louisville, Kentucky. Following a determination that the boxes contained marijuana, arrangements were made to fly them to Massachusetts State police who organized the controlled delivery.
¶11The officer who made these observations was nearby with a video camera and taped the delivery only up to this point because the camera’s battery failed. The tape was viewed in court, and the officer provided some narrative, which is transcribed in the record. Our viewing of the tape indicates that it does not contain any significant information beyond what is reflected in the transcript.
¶12In announcing his decision, the judge stated he found the defendant’s statement “incredible,” and that the statement was evidence of consciousness of guilt or a “consciousness of the contents.”
¶13Miranda v. Arizona, 384 U.S. 436 (1966).
¶14Ordinarily the admissibility of a statement is to be determined in a pretrial hearing. Here, the defendant had filed a motion to suppress, and a hearing had been held by another judge who denied the motion. However, the defendant’s statement was not at issue in that hearing. Our record does not contain the memorandum filed by that judge, but we have a transcript of that hearing, which appears to have involved only the validity of search warrants issued in Kentucky and Massachusetts and issues .related to police examination of the boxes.
¶15The defendant asserts the Commonwealth’s argument concerning custody is made for the first time on appeal. We disagree. Although the argument is brief, the prosecutor stated to the judge that “[tjhere is nothing that indicates that the environment was a police setting, where there was a number of officers around who are armed, where the defendant was out of his element. . . . [Njothing that was said nor the conditions did anything to overbear this defendant’s ability to exercise his rights. . . .”
¶16The defendant concedes that under “comparable facts” in these two recent cases we have ruled that the failure to introduce the card was not fatal. See Commonwealth v. Mitchell, supra at 181 (inconsequential that during voir dire officer could not recall exact rights read to defendant in view of testimony that he read the rights from a Miranda card, and the defendant specifically indicated he understood his rights); Commonwealth v. Rendon-Alvarez, supra at 141 (not error for judge to conclude defendant was properly warned although officer could not recall all the warnings, where defendant had been given card to read at roadside and later warnings were read to defendant from such a card). See also Commonwealth v. Preston, 359 Mass. 368, 372 & n.2 (1971) (affirming judge’s finding that Miranda warnings given based on officer’s testimony and that defendant was shown a card). The present case is unlike Commonwealth v. Ayala, 29 Mass. App. Ct. 592, 598 (1990), and Com*55monwealth v. Coplin, 34 Mass. App. Ct. 478, 481-483 (1993), where one of the four warnings was omitted.
¶17While it is good practice to introduce Mirandacards in evidence, see Commonwealth v. Lewis, 374 Mass. 203, 204-205 (1978), it has not been held, in the cases cited to us, that the failure to do so undermines a judicial finding, based on all the evidence, that Miranda warnings had been given. Such findings have support in the fact that “Miranda has become embedded in routine police practice to the point where the warnings have become part of our national culture.” Dickerson v. United States, 530 U.S. 428, 444 (2000).
¶18The defendant, in additional arguments (raised for the first time in this appeal, and, therefore, not considered by us), notes that the rulings of Mitchelland Rendon-Alvarezdid not consider the best evidence rule, complains that a police officer’s testimony is incompetent evidence of what is actually on a Miranda card, and argues the best evidence rule as further justification for requiring the introduction of the card in evidence.
