    M ANION, Circuit Judge. After a traffic stop, officers found
    over four kilograms of methamphetamine hidden in the
    bumpers of the Honda Civic in which the defendants
    Thomas Prieto and Fernando Sanz (collectively “the
    appellants”) were traveling. The appellants were both
    charged with possessing with the intent to distribute
    more than 500 grams of a substance containing metham-

    phetamine in violation of 21 U.S.C. § 841(a)(1). After a
    three-day trial, a jury found Prieto and Sanz guilty. They
    appeal, alleging a variety of trial errors. We affirm.
    I.
    On August 26, 2005, Commander Oscar Martinez of the
    Lake County Police Department was about to finish his
    patrol for the day when he noticed the Honda Civic in
    which Prieto and Sanz were traveling veer on and off
    the highway’s shoulder on I-65 south of the Crown Point,
    Indiana, exit. Martinez stopped the Civic. A video camera
    mounted inside Martinez’s police cruiser captured the
    entire stop. In addition, a microphone in the police
    cruiser and another attached to Martinez captured the
    conversations between Martinez, Sanz, and Prieto during
    the stop. The government introduced the video and
    audio recordings from the stop at the appellants’ trial.
    After pulling the Civic over, Martinez approached the
    vehicle and asked Sanz, the driver, for his driver’s license.
    Sanz, his hands shaking, handed Martinez his Mexican
    license. Sanz told Martinez that the Civic was registered
    to a “Nicolas Cardenas.” Later investigation revealed that
    the car indeed was registered to “Nicolas Cardenas.” Also
    revealed, however, was that Sanz had been arrested ten
    months earlier using the alias “Nicolas Cardenas”—the
    social security number listed on the title for the Civic
    matched the number Sanz had given at the booking
    after his prior arrest.
    Martinez had Sanz step out of the Civic. Both Prieto and
    Sanz appeared extremely nervous. Martinez questioned
    Nos. 07-3484 & 07-3485                                       3
    each of the men out of earshot of the other about the
    purpose of their trip. They gave conflicting accounts of
    the reason for their travel. Sanz told Martinez that they
    were traveling from Lafayette, Indiana, to Chicago for the
    day to visit friends and to look for a job. Prieto, on the
    other hand, told Martinez that they were going to Chicago
    for several days to visit family. Martinez issued Sanz a
    warning for unsafe lane movement and asked—in
    Spanish—for permission to search the vehicle, which Sanz
    granted. Martinez placed Prieto and Sanz in the rear of
    his police cruiser, returned to the Civic, and began search-
    ing the vehicle.
    While Martinez searched the Civic, Prieto and Sanz
    discussed their responses to Martinez’s queries about the
    purpose of their trip. The microphone inside Martinez’s
    cruiser recorded that conversation 1 :
    PRIETO: I told him, “We’re going to go see the fam-
    ily.”
    SANZ:     What?
    PRIETO: That we’re going to go see the family.
    SANZ:     Yeah. [SIGHS]

    Prieto and Sanz conversed in Spanish. The government
    provided a translation of their conversation in English for the
    jury at trial. The government also provided an English transla-
    tion of Prieto and Sanz’s jail phone conversation with Nuco,
    which we discuss later in this opinion.

    SANZ:    Where did you tell him we were going?
    PRIETO: To Chicago.
    SANZ:    “We’re going to Chicago to . . .”
    PRIETO: “To go see family.”
    SANZ:    Huh?
    PRIETO: “To go see some family.”
    SANZ:    Yeah uh, I told him we were going to go, go
    see some people because we were looking for
    a job.
    PRIETO: Oh.
    When Martinez’s search took him towards the Civic’s
    bumpers, Sanz and Prieto’s conversation changed topics:
    SANZ:    [SIGHS] Son of a bitch. Don’t tell me he’s
    headed towards the bumper. [SIGHS]
    ***
    PRIETO: They went towards the bumper.
    SANZ:    Huh?
    PRIETO: They went towards the bumper.
    SANZ:    [SIGHS]
    PRIETO: They went towards the bumper?
    SANZ:    Huh?
    PRIETO: They went towards the bumper?
    SANZ:    No, they can’t see it.
    Nos. 07-3484 & 07-3485                                5
    Examining the front bumper, Martinez noticed two things
    indicative of a hidden compartment: fresh paint and
    “bondo,” a type of plaster. Moving to the rear bumper,
    Martinez reached into the hollow part at the end of the
    bumper, felt plastic packaging, and pulled out a bag
    containing a white powder substance. Recognizing that
    the powder was narcotics, Martinez ordered both Prieto
    and Sanz at gunpoint to exit the police car and arrested
    them.
    Handcuffed, and once again inside the police cruiser,
    the appellants lamented the turn of events:
    PRIETO: We’re fucked.
    SANZ:     Now we’re really fucked.
    PRIETO: Huh?
    SANZ:     Now we’re screwed.
    Their conversation continued:
    PRIETO: How are they going to know. Did they un-
    cover the front?
    SANZ:     Huh?
    PRIETO: Did they cover up the front?
    SANZ:     Yes.
    PRIETO: That’s why.
    ***
    PRIETO: We don’t know anything.

    PRIETO: Did they get it out?
    SANZ:    Huh?
    PRIETO: Did they get it out?
    SANZ:    No. [PAUSE] [SIGHS] You don’t know, you
    don’t know. Right?
    PRIETO: Huh?
    SANZ:    You don’t know, you don’t know.
    PRIETO: Uh-huh.
    SANZ:    [SIGHS] Supposedly the car’s owner is out.
    PRIETO: He’s out and we don’t know. They just let
    us borrow it.
    The appellants continued to watch Martinez, who, along
    with another officer, had removed the rear bumper and
    the packages of narcotics contained therein and were
    turning their attention to the front bumper. As the
    officers began chiseling away at the front bumper, the
    appellants’ discussion continued:
    SANZ:    I never liked it [UNINTELLIGIBLE].
    PRIETO: How was it?
    SANZ:    It was fat, fat, fat and [UNINTELLIGIBLE]
    in the middle.
    PRIETO: Oh.
    PRIETO: What the fuck are they doing?
    SANZ:    [CLEARS THROAT] They’re going to rip the
    bumper in the middle.
    Nos. 07-3484 & 07-3485                                     7
    PRIETO: Is there more in the middle?
    ***
    SANZ:     Yes.
    ***
    PRIETO: [UNINTELLIGIBLE] We’re fucked.
    Unable to completely dismantle the front bumper on
    the roadside, the officers placed the front bumper in one
    of the officers’ patrol car and took it to the police ga-
    rage. The officers also transferred the defendants from
    Martinez’s cruiser to the back of another patrol car and
    transported them to the police garage as well. At the
    police garage, Martinez and the other officers finished
    dismantling the front bumper and found several pack-
    ages of narcotics inside.
    While the officers were en route to the police garage, they
    informed Lake County Police Officer Lessie Smith (who
    was on assignment to a DEA task force) that they had
    stopped a car with drugs and were going to the police
    garage. Smith headed over to the garage. When she
    arrived, she saw Martinez in possession of the packages
    of narcotics, which were on the garage floor. After Marti-
    nez placed the packages on a vehicle lift where they were
    photographed, Smith and a police detective put the
    narcotics in a DEA evidence bag, drove them to her
    office, and placed them in the evidence room. DEA Agent
    David Ritchie assisted in packaging, processing, and
    sealing the narcotics for evidence. The drugs were
    placed in unique packages bearing Ritchie’s name
    and handwriting.

    Less than two weeks after their arrest, Prieto and Sanz
    made a joint telephone call from the Porter County jail to
    someone they identified as “Nuco.” That conversation
    was recorded:
    NUCO:    Hello?
    PRIETO: What’s up?
    NUCO:    What’s happening, man?
    PRIETO: Nothing, man.
    NUCO:    What . . . What’s has [sic] been going on?
    PRIETO: Nothing. We are here.
    NUCO:    Where?
    PRIETO: Here at the little school.
    NUCO:    Oh!
    PRIETO: Yeah.
    ***
    NUCO:    That guy wants . . . but exactly what it is,
    man. How the things are, how they went,
    and everything.
    PRIETO: Uh-huh.
    NUCO:    So . . . so in some way that . . . and what
    name you guys gave, man. Because you guys
    don’t come up.
    PRIETO: Well, look. Well, my name is Tomas Prieto.
    NUCO:    Oh, yeah? And the other one?
    PRIETO: Yeah. And Fernando Sanz. Fernando Sanz.
    Nos. 07-3484 & 07-3485                                        9
    Nuco assured Prieto and Sanz not to think that “anyone is
    leaving you guys behind.” He continued:
    NUCO:     Hey, man, and but . . . and . . . what . . . how
    did it go down? More or less I mean . . .
    SANZ:     No, no, no. It was a traffic stop. It was a ru. . .
    traffic stop. I mean, the lawyer told me
    that maybe it was for our appearances, you
    know what I mean?
    NUCO:     Uh-huh.
    SANZ:     Hispanic. That the . . . that the . . . [STUT-
    TERS] police officer stopped us.
    NUCO:     Uh-huh.
    SANZ:     And um . . . and well . . . all of the . . . came
    out . . . he took out all of the shit.
    NUCO:     But . . . did it go out straight or how . . . how?
    SANZ:     Yeah. It went . . . it went more or less. Don’t
    think that it went . . . but that supposedly
    this dude . . . is uh . . . he had experience in
    that shit. You know what I mean?
    NUCO:     Mm-hmm.
    SANZ:     And it left, well not . . . not exactly . . . it
    didn’t go out full, but that . . . that . . . that
    apparatus that was in the front caught
    his attention.
    NUCO:     Oh, yeah?
    SANZ:     Yeah.

    NUCO:   It’s just that you guys didn’t come up, so
    he wanted . . . the dude wanted to know
    exactly in what county and everything. Well,
    the one from here. Well the lawyer so that
    he . . . could go over there directly.
    SANZ:   Yeah, yeah. No, no . . .
    NUCO:   Because he was checking but because you
    guy[s] didn’t come up. He said, “Well,
    I don’t know why. Or ask them exactly if
    they gave another name.”
    SANZ:   It’s just that man something happened that
    was similar to . . . to . . . [UNINTELLIGIBLE]
    those. You see that we . . . [STUTTERS] . . .
    how can I say it? They . . . uh . . . right away
    they passed us to the . . . well, to the federal
    department.
    NUCO:   Let me see. Hold on. What did you say . . .
    did you give for your name?
    SANZ:   My name is Fernando Sanz.
    NUCO:   Hold on. [PAUSE] Fernando Sanz? Sanz?
    SANZ:   Yeah. Yes.
    NUCO:   Uh-huh. And the other one Tomas Prieto?
    SANZ:   Tomas Prieto. [PAUSE] Tell him that on . . .
    on the twenty-sixth [26th] we are going to
    have the . . . the other court.
    Before the conversation ended, Nuco again assured the
    appellants that “nobody is leaving you behind.”
    Nos. 07-3484 & 07-3485                                   11
    Both Prieto and Sanz were charged with one count of
    possessing with the intent to distribute more than 500
    grams of a substance containing a detectable amount of
    methamphetamine in violation of 21 U.S.C. § 841(a)(1). At
    trial, the government’s first witness was Martinez.
    During the prosecutor’s questioning of Martinez about
    the events leading up to the appellants’ arrests, the fol-
    lowing exchange occurred in which Martinez referenced
    the appellants’ post-arrest silence:
    PROSECUTOR: And after they were handcuffed,
    what did you do with the Defen-
    dants or what did your fellow offi-
    cers do with the Defendants?
    MARTINEZ:         We put them back in my police car.
    They said nothing at all.
    Neither of the appellants’ attorneys objected. Later, the
    prosecutor played the video recording of the traffic stop
    for the jury on fast-forward and had Martinez narrate
    what was happening. Towards the end of that narration,
    Martinez stated that he told “Officer Musgrove to hand-
    cuff [Sanz]. And neither Mr. Sanz or Mr. Prieto said
    anything.” This time, Sanz’s attorney objected and moved
    for a mistrial. The court initially overruled the objection,
    but later, after a break in testimony and a chance to
    confer with the parties, struck the testimony from the
    record and gave this curative instruction to the jury:
    Officer Martinez testified on direct examination that
    the Defendants did not say anything when they were
    being placed under arrest. The Defendants have an
    12                                   Nos. 07-3484 & 07-3485
    absolute right to remain silent. The fact that the Defen-
    dants did not say anything may not be considered by
    you in any way in arriving at your verdict. That
    testimony is stricken from the record, and you
    are admonished to disregard it.
    After the court gave that instruction, no further mention
    was made of the appellants’ post-arrest silence.
    Along with the transcripts of the conversations
    between Prieto and Sanz in the back of Martinez’s police
    cruiser, the government also introduced into evidence
    the transcript of the telephone call made to Nuco from
    the Porter County jail. Prior to trial, the government had
    filed a Santiago proffer (see United States v. Santiago, 
    582 F.2d 1128
    (7th Cir. 1978)) announcing its intention to
    introduce Nuco’s statements under Federal Rule of Evi-
    dence 801(d)(2)(E) as statements by a co-conspirator
    made during the course of a conspiracy and in further-
    ance of it. The court conditionally admitted Nuco’s state-
    ments subject to the Santiago requirements. When, during
    trial, the government attempted to lay the foundation for
    the introduction of the transcript of the jail telephone call
    through Agent Ritchie, the prosecutor and Ritchie had the
    following exchange:
    PROSECUTOR: Can you tell us in September of 2005,
    in connection with another investiga-
    tion that you had, what you did to
    further the investigation against
    these two defendants?
    RITCHIE:          The investigation was furthered by
    obtaining the telephone calls that
    Nos. 07-3484 & 07-3485                                  13
    were made from the jail, the Porter
    County jail.
    ***
    PROSECUTOR: At the time in September of 2005,
    were you working on another inves-
    tigation?
    RITCHIE:         Yes sir, I was.
    PROSECUTOR: And what did that investiga-
    tion—what about that investigation
    made you think that it would be
    useful to get telephone calls from the
    Porter County jail from these Defen-
    dants?
    ***
    RITCHIE:         The investigation that I was involved
    in at that time involved drug traffick-
    ers in Lafayette, Indiana whose
    source of supply was in Chicago. The
    fact that these individuals were
    stopped driving from Lafayette to
    Chicago with a large amount of
    m ethamphetamine made m e
    believe there is a possible connection.
    The attorneys for both Prieto and Sanz objected to this
    line of questioning and, after a bench conference, moved
    for a mistrial on the grounds that Ritchie’s testimony
    violated Federal Rule of Evidence 404(b). The court
    denied that motion, stating:
    14                                   Nos. 07-3484 & 07-3485
    I don’t view this as 404-B evidence. Again, the reason
    the question was asked is there was some reason that
    this witness went to the Porter County jail to order up
    the phone calls that we’re about to hear, I am presum-
    ing. So, the Government, it seems to me, wants to put
    into context why he did that. Now, that’s not 404 B. It’s
    not at all stating that these Defendants engaged in
    some other act. In fact, as counsel says, they didn’t do
    those things. So, it’s not another act under Rule 404-B.
    And it is—if it were, it would be inextricably inter-
    twined with this investigation.
    So the objection is overruled. If you want me to give
    some curative instruction to the jury that—along the
    lines that that line of inquiry was only being offered to
    place into context why the agent pulled the
    phone calls, I’m glad to do that.
    Sanz’s attorney declined the court’s offer for a curative
    instruction, stating that he thought such an instruction
    would “just draw[ ] more attention to it.”
    Ritchie also testified that the methamphetamine exhibits
    the government presented were the same exhibits he
    assisted in packaging as evidence on the day Prieto and
    Sanz were arrested. He testified that he transported the
    drugs from the evidence room to the DEA’s laboratory in
    Chicago for testing by a DEA chemist. During the testi-
    mony of the DEA chemist, however, the appellants’
    attorneys objected to the introduction of the methamphet-
    amine exhibits, arguing that the government had failed
    to show a proper chain of custody. The district court
    denied the objection and ruled that, while the govern-
    Nos. 07-3484 & 07-3485                                    15
    ment’s presentation of evidence bearing on the chain of
    custody was “somewhat sloppy,” a presumption of
    regularity applied because the drugs had not left police
    custody. It further held that any breaks in the chain of
    custody went to the weight of the evidence, rather than
    its admissibility.
    At the conclusion of the government’s case, the district
    court found that the appellants’ statements during the
    jailhouse phone call were made in furtherance of the
    conspiracy and thus that the government had satisfied
    Santiago, making the statements admissible for all pur-
    poses. The court then entertained motions from the appel-
    lants’ counsel, and counsel for the appellants moved for
    a judgment of acquittal based on the absence of a formal in-
    court identification of the appellants as the men Martinez
    arrested. The district court denied the motion and gave
    the following explanation:
    I was also surprised that there wasn’t an in-court
    identification, frankly, of either Defendant. But antici-
    pating that, in United States versus Weed[ ], 
    689 F.2d 752
    , it’s a Seventh Circuit case from 1982, the Court
    said the following. Generally, an in-court identification
    of the accused is an essential element in the establish-
    ment of guilt beyond a reasonable doubt. However,
    identification can be inferred from all of the facts and
    circumstances that are in evidence.
    ***
    Based on the evidence presented in this case, I am
    satisfied that the Government has established that the
    two gentlemen sitting in court here are . . . the same
    16                                    Nos. 07-3484 & 07-3485
    gentlemen that were arrested at the scene of their
    arrest on I-65. That is linked up first and foremost by a
    videotape at the scene of both Mr. Prieto and Mr. Sanz,
    who appear the same as the two individuals sitting in
    court here today.
    It’s further tied up by the—as it relates to Mr. Sanz,
    the Mexican license that was handed over to Com-
    mander Martinez, and that photograph does meet the
    description of Mr. Sanz broadly.
    In addition, I do agree that there were several occa-
    sions that I did notice and did see Commander Marti-
    nez when he was referring either to Mr. Prieto—both to
    Mr. Prieto and to Mr. Sanz, and interchangeably
    referring to them as the Defendants, him referencing
    and pointing to them here in open court.
    Neither appellant testified or called any witness in his
    defense. The jury found both Prieto and Sanz guilty. The
    district court sentenced Prieto to 235 months’ imprison-
    ment and Sanz to 262 months’ imprisonment. Both
    Prieto and Sanz appeal their convictions.
    II.
    The appellants first argue that Martinez’s testimony
    about their post-arrest silence warranted a mistrial.2
    2
    Because the district court later struck Martinez’s testimony,
    Sanz’s argument that the district court abused its discretion
    in admitting Martinez’s testimony is moot. However, we do
    (continued...)

    “[B]ecause the trial court ‘is in the best position to deter-
    mine the seriousness of the incident in question, particu-
    larly as it relates to what has transpired in the course of
    the trial,’ we review the court’s denial of a motion for
    mistrial for an abuse of discretion.” United States v. Curry,
    
    538 F.3d 718
    , 726-27 (7th Cir. 2008) (quoting United States
    v. Danford, 
    435 F.3d 682
    , 686 (7th Cir. 2006)). “We will
    reverse a district court’s denial of a mistrial only if we have
    a strong conviction that the district court erred. The
    ultimate inquiry is whether the defendant was deprived of
    a fair trial.” 
    Danford, 435 F.3d at 686

    marks and citation omitted).
    “[T]he Fifth Amendment, in its direct application to
    the Federal Government . . . forbids either comment by
    the prosecution on the accused’s silence or instructions

    States v. Jumper, 
    497 F.3d 699
    , 704 (7th Cir. 2007) (quoting
    Griffin v. California, 
    380 U.S. 609
    , 615 (1965)). In support
    of their contention that they should be granted a mistrial,
    the appellants invoke the Supreme Court’s decision in
    Doyle v. Ohio, 
    426 U.S. 610
    (1976). The question in Doyle
    was whether a prosecutor can impeach a defendant on
    the stand with his post-arrest silence; the Supreme
    Court answered in the 
    negative. 426 U.S. at 611

    Prieto nor Sanz explains how Doyle applies here, where

    appellants’ post-arrest silence arose in the context of a
    witness’s stray remarks during the narrative portions of
    his testimony, and the prosecutor neither intentionally
    elicited the testimony nor argued any adverse inferences
    to the jury from the silence. Compare 
    Jumper, 497 F.3d at 706-07
    (finding harmless error where district court admit-
    ted portions of a video-taped interrogation during which
    the defendant invoked his right to remain silent), with
    Lindgren v. Lane, 
    925 F.2d 198
    , 200-01 (7th Cir. 1991) (find-
    ing witness’s reference to the defendant’s silence, without
    evidence that the prosecutor used or was permitted to
    use that testimony, did not violate the Fifth and Four-
    teenth Amendments).
    We need not dwell on the appellants’ failure to address
    the applicability of Doyle. Even assuming Martinez’s
    statements violated the appellants’ Fifth Amendment
    rights, any error resulting from the jury hearing that
    testimony was undoubtedly harmless. Recall that Martinez
    only mentioned the defendants’ post-arrest silence twice.
    The first time Martinez remarked “they said nothing at
    all” in response to the prosecutor’s question about what
    Martinez did with the defendants after handcuffing them.
    The second time Martinez stated “neither Mr. Sanz or
    Mr. Prieto said anything” towards the end of his narra-
    tion of the video recording of the traffic stop. The
    district court struck both of those statements from the
    record and admonished the jury to disregard them. See
    United States v. Robbins, 
    197 F.3d 829
    , 836 (7th Cir. 1999)
    (“Errors that are the subject of curative instructions are
    presumed harmless.”). The references themselves were
    short and not intentionally elicited by the prosecutor. The
    Nos. 07-3484 & 07-3485                                   19
    prosecutor did not highlight the appellants’ silence by
    asking Martinez any follow-up questions, and he did not
    broach the subject with any other witness or at closing
    argument. See 
    Jumper, 497 F.3d at 707
    .
    In addition, the evidence of Prieto’s and Sanz’s guilt
    was overwhelming. The Civic in which the appellants
    were traveling contained a massive quantity of hidden
    methamphetamine. The car was registered to “Nicolas
    Cardenas,” an alias that Sanz had previously used. The
    appellants were nervous and gave conflicting stories
    about their travels. And the appellants’ conversations
    both in the back of Martinez’s patrol car and with Nuco
    speak for themselves, plainly exposing their guilt. In light
    of that clear evidence of the appellants’ guilt, we can
    confidently say that the temporary admission of Martinez’s
    statements about the appellants’ silence was harmless
    beyond a reasonable doubt. See 
    id. at 706
    (“An error is
    harmless if it appears ‘beyond a reasonable doubt that
    the error complained of did not contribute to the verdict
    obtained.’ ” (quoting Ben-Yisrayl v. Davis, 
    431 F.3d 1043
    , 1052 (7th Cir. 2005))).
    Next, the appellants make two challenges to the
    district court’s denial of their motion for a mistrial based
    on Agent Ritchie’s statements about the possible connec-
    tion between the appellants and another drug investiga-
    tion. They first argue that Ritchie’s statements were
    inadmissible propensity evidence and should have been
    excluded under Federal Rule of Evidence 404(b). In the
    alternative, Sanz contends that the statements should
    have been excluded under Federal Rule of Evidence 403
    20                                   Nos. 07-3484 & 07-3485
    because the probative value of the proffered evidence was
    substantially outweighed by the danger of unfair
    prejudice.3 In response, the government argues that
    Rule 404(b) was not implicated because Ritchie only
    spoke of a “possible connection” and did not state that the
    appellants had in fact engaged in other illegal drug activ-
    ity. The government also asserts that the testimony was
    “inextricably intertwined” with this case and necessary
    to explain why Ritchie retrieved the recordings of the
    appellants’ phone calls from the Porter County jail.
    Ritchie’s testimony linking the appellants to another
    drug investigation was not necessary to provide context
    for his interception of the phone calls. The prosecutor
    could have given the jury all the context it needed simply
    by eliciting testimony from Ritchie that the telephone
    conversations of prisoners are routinely recorded and
    that federal agents routinely (or occasionally) listen to
    those conversations in preparation for trial. Providing
    context in that way would have avoided the possibility
    of any prejudice arising from connecting the appellants to
    another drug investigation. Instead, the prosecutor
    chose a more problematic route.
    That being said, any error that may have arisen from the
    admission of this testimony was harmless. 4 Ritchie only

    We note that Sanz did not present this Rule 403 argument to
    the district court, so we review it for plain error only.
    United States v. Sloan, 
    492 F.3d 884
    , 895 (7th Cir. 2007).
    4
    Because we conclude that any error would be harmless, we
    need not rule on whether the district court abused its discre-
    (continued...)
    Nos. 07-3484 & 07-3485                                     21
    spoke of a possible connection to the other investigation
    and his testimony on the subject was brief. Again, the
    evidence against the appellants was overwhelming. Thus,
    the admission of Ritchie’s statements did not affect the
    outcome of the trial, and the district court’s decision
    denying the appellants’ motion for a mistrial need not
    be reversed. See United States v. Ratliff-White, 
    493 F.3d 812
    ,
    826 (7th Cir. 2007) (“Errors do not merit reversal when
    the government proves that they are harmless, that is, that
    they did not affect the outcome of the trial.” (quoting
    United States v. Ortiz, 
    474 F.3d 976
    , 982 (7th Cir. 2007))).
    For the appellants’ next contention of error, Sanz ques-
    tions the district court’s ruling that Nuco’s statements
    during the jail phone conversation were admissible pursu-
    ant to Federal Rule of Evidence 801(d)(2)(E). We review
    a district court’s ruling on the admissibility of evidence
    for an abuse of discretion. United States v. Jackson, 
    540 F.3d 578
    , 587 (7th Cir. 2008). “In order for a statement
    made by a member of a conspiracy to be admissible
    against other members of the conspiracy under Rule
    801(d)(2)(E), the government must prove by a preponder-
    ance of the evidence that (1) a conspiracy existed; (2) the
    defendant and the declarant were members of the con-
    spiracy; and (3) the statement was made during the course
    and in furtherance of the conspiracy.” United States v.
    Schalk, 
    515 F.3d 768
    , 775 (7th Cir. 2008).
    Sanz contends that there was not enough evidence to
    establish by a preponderance that Nuco, Prieto, and Sanz
    4
    (...continued)
    tion in admitting Ritchie’s testimony.
    22                                  Nos. 07-3484 & 07-3485
    were involved in an existing conspiracy and that Nuco’s
    statements 5 were made during the course and in further-
    ance of that conspiracy. On the contrary, the record is
    replete with evidence that Nuco, Prieto, and Sanz con-
    spired to transport narcotics and that the jailhouse phone
    conversation between those three was in furtherance
    of that conspiracy. Although not charged, the evidence
    supports a finding of a conspiracy between Prieto and
    Sanz to transport methamphetamine for distribution. See
    United States v. Moon, 
    512 F.3d 359
    , 363 (7th Cir. 2008)
    (observing that a prosecutor need not charge a con-
    spiracy to take advantage of Rule 801(d)(2)(E)). Further-
    more, the subject matter and tenor of the jailhouse con-
    versation indicate that Nuco participated in the con-
    spiracy and that the purpose of the call was to further the
    conspiracy—in particular, for Prieto and Sanz to report
    their status to Nuco and, in turn, receive assurances of
    assistance from their co-conspirators. Cf. United States v.
    Potts, 
    840 F.2d 368
    , 371 (7th Cir. 1987) (finding that a
    conversation reporting on the conspiracy’s progress was
    in furtherance of the conspiracy); United States v. Buishas,
    
    791 F.2d 1310
    , 1315 (7th Cir. 1986) (finding assurances
    given by a co-conspirator that he could be trusted to
    perform his role admissible as statements in furtherance
    of the conspiracy). At the beginning of the conversation,
    the appellants apprised Nuco of their status. That Nuco
    appeared familiar with Prieto and Sanz (“What’s happen-
    ing, man?” “What’s . . . been going on?”) yet did not

    Sanz does not challenge the admission of Prieto’s state-
    ments during the phone conversation against him.
    Nos. 07-3484 & 07-3485                                    23
    know what “name you guys gave” is telling, as it
    suggests that the members of the conspiracy were using
    aliases to protect the conspiracy. Nuco then requested the
    details of their capture—information that would be of
    great value to any continuing efforts to smuggle narcotics
    through northern Indiana. Near the end of the conversa-
    tion, Nuco gave repeated assurances to the appellants
    that no one was leaving them behind. Those assurances
    demonstrated that the conspiracy was ongoing, since
    they reasonably implied that the other members of the
    conspiracy would take care of Prieto and Sanz if they did
    their part and did not divulge any information to the
    authorities. From that evidence, the district court was
    well within its discretion to conclude that Nuco’s state-
    ments were made in furtherance of an ongoing con-
    spiracy, and we will not disturb its ruling.
    The appellants also challenge the chain of custody of
    the government’s methamphetamine exhibits. We review
    for an abuse of discretion the district court’s evidentiary
    rulings on the chain of custody for physical exhibits.
    United States v. Lee, 
    502 F.3d 691
    , 697 (7th Cir. 2007). “The
    standard for the admission of exhibits into evidence is
    that there must be a showing that the physical exhibit
    being offered is in substantially the same condition as
    when the crime was committed.” 
    Id. (quoting United
    States v. Moore, 
    425 F.3d 1061
    , 1071 (7th Cir. 2005)). “In
    making this determination, the district court makes a
    ‘presumption of regularity,’ presuming that the govern-
    ment officials who had custody of the exhibits dis-
    charged their duties properly.” United States v. Scott, 
    19 F.3d 1238
    , 1245 (7th Cir. 1994). The chain of custody need
    not be perfect; gaps in the chain go to the weight of the
    24                                  Nos. 07-3484 & 07-3485
    evidence, not its admissibility. 
    Lee, 502 F.3d at 697
    . In
    addition, the government does not have to exclude all
    possibilities of tampering with the evidence. Instead, the
    government need only show that “it took reasonable
    precautions to preserve the original condition of the
    evidence.” 
    Id. (quoting United
    States v. Lott, 
    854 F.2d 244
    , 250 (7th Cir. 1988)).
    The district court’s decision to admit the methamphet-
    amine exhibits was not an abuse of discretion. True, as the
    district court pointed out, the government could have
    done a better job establishing exactly what happened to
    the packages of drugs before they ended up on the floor
    of the police garage. For instance, the government did not
    offer any testimony about what happened to the drug
    packages removed from the rear bumper from the time
    they were removed to the time they appeared on the
    floor of the police garage. Nevertheless, the district court
    did not err in admitting the exhibits because such
    minor gaps in the chain go to the weight of the metham-
    phetamine exhibits rather than their admissibility. More-
    over, because no evidence in the record indicated that
    the narcotics ever left police custody, the presumption of
    regularity therefore applies. Although the appellants
    argue against the presumption on the grounds that
    two reporters and a tow-truck driver were in the
    vicinity with the officers at the time of their arrest, the
    appellants have not pointed to any evidence of tampering.
    As we have said before, “[m]erely raising the possibility
    of tampering is not sufficient to render evidence inad-
    missible; the possibility of a break in the chain of custody
    of evidence goes to the weight of the evidence, not its
    admissibility.” United States v. Kelly, 
    14 F.3d 1169
    , 1175
    Nos. 07-3484 & 07-3485                                    25
    (7th Cir. 1994). The district court therefore did not err
    when it admitted the methamphetamine exhibits into
    evidence and allowed the jury to determine what weight
    that evidence deserved.
    Lastly, the appellants contend that the district court
    should have granted their motion for acquittal because
    the government failed to elicit an in-court identification of
    the appellants. In denying the appellants’ motion, the
    district court cited United States v. Weed, 
    689 F.2d 752
    (7th
    Cir. 1982). We held in Weed that the lack of an in-court
    identification of the defendant did not require a judg-
    ment of acquittal. Although recognizing that an in-court
    identification of the accused is generally required to
    establish guilt beyond a reasonable doubt, we observed
    that identification can also “be inferred from all the facts
    and circumstances that are in evidence.” 
    Weed, 689 F.2d at 754
    . We found from the following facts and circum-
    stances in Weed that the identification of the defendant
    could be inferred:
    In this case, three Customs agents testified re-
    garding the events of the evening of December 22, 1977
    and the statements made by Weed. None of these
    witnesses during the bench trial noted that the defen-
    dant was not the same John Weed stopped in 1977.
    Both the prosecution and defense counsel referred to
    the defendant at trial as the John Weed involved in
    the December, 1977 events. At no time did defense
    counsel object to the prosecution’s references to “the
    defendant.” Appellate counsel, who was also
    defense counsel, admitted at oral argument to this
    26                                   Nos. 07-3484 & 07-3485
    Court that he realized no identification had been
    made during the testimony of the third witness, yet
    he still did not object to references to the defendant.
    
    Id. at 755-56.
      As in Weed, the identification of Prieto and Sanz could
    be inferred from all the facts and circumstances in evi-
    dence. Commander Martinez repeatedly referred to Prieto
    and Sanz by name during his testimony and, as the
    district court noted, repeatedly pointed to them when
    he referred to them in open court as the men he arrested.
    In addition, the jury could compare Prieto and Sanz to the
    men in the video of the traffic stop that was played twice
    during trial and identify them that way. Thus, the gov-
    ernment’s failure to explicitly elicit an in-court identifica-
    tion of Prieto and Sanz was not fatal to the government’s
    case, and the district court did not err in denying the
    appellants’ motion for a judgment of acquittal on that
    basis.
    III.
    The evidence against the appellants was overwhelming.
    Thus, the district court did not err in briefly admitting
    Martinez’s stray comments about the appellants’ post-
    arrest silence. Nor, for the same reason, did it err in
    admitting Agent Ritchie’s statement about Prieto and
    Sanz’s possible connection to another drug investigation.
    The district court also did not abuse its discretion by
    admitting Nuco’s statements from the jail telephone
    conversation because the evidence supported the court’s
    Nos. 07-3484 & 07-3485                                   27
    finding that the call was in furtherance of a conspiracy
    involving Nuco and the appellants. In addition, the
    district court did not abuse its discretion in admitting
    the methamphetamine exhibits because any minor break
    in the chain of custody went to the weight of the
    exhibits rather than their admissibility. Finally, since the
    jury could have inferred the identification of Prieto and
    Sanz from all the facts and circumstances in evidence,
    the appellants were not entitled to a mistrial due to the
    lack of a formal in-court identification. We A FFIRM .
