    Appeal from the United States District Court

    (97-CR-191-11)
    _________________________________________________________________
    August 24, 1999
    Before SMITH, WIENER, and BARKSDALE, Circuit Judges.
    PER CURIAM:1
    1
    Pursuant to 5TH CIR. R. 47.5, the Court has determined that
    this opinion should not be published and is not precedent except
    under the limited circumstances set forth in 5TH CIR. R. 47.5.4.
    Appellants having been convicted, inter alia, for conspiracy
    to commit both bank fraud and bank larceny, primarily at issue are
    the convictions’ evidentiary sufficiency and Sentencing Guidelines’
    increases.      We AFFIRM.
    I.
    In   May    1996,   a   predecessor        to   Wells   Fargo    Bank   hired
    Christopher Merhan as a teller at its branch in Houston, Texas.
    Typically, Merhan worked in the mornings and, with supervisor
    Kenneth Chandler, was responsible for opening the branch.
    For security reasons, the three-number combination to the main
    vault door was divided among two people.                To open the vault each
    morning, Merhan was given the first two numbers; Chandler, the
    last.   Unknown to his superiors, Chandler, because sometimes late
    to work, gave Merhan that last number, so that he, alone, could
    open the vault.
    At trial, the Government claimed that Merhan became involved
    in a bank fraud scheme in early 1997.            The leader was Tai Duc Lai,
    known as “Calvin”.       Merhan and co-defendant Dhonovan Serrano were
    acquainted with Calvin.
    Calvin     testified    that   he    was    able   to   make    unauthorized
    withdrawals from bank accounts as a result of information Merhan
    gave him.       Sometimes using Serrano as a conduit, Merhan would
    - 2 -
    supply Calvin with account information, including account numbers,
    balances, and the names and addresses of the account holders.
    Calvin then recruited “runners”, who would visit bank branches and,
    using false Texas drivers’ licenses provided by Calvin, withdraw
    money from the accounts. In return, the runner and Merhan received
    payment out of the fraudulently withdrawn funds.
    The Government presented evidence that, the day after Merhan
    handled a deposit for the account of Quaker Loh on 13 March 1997,
    an unauthorized withdrawal of $2400 was made from it.               Another
    unauthorized withdrawal, in the amount of $2500, was made a few
    days later; Merhan was the teller for this withdrawal.
    Further,   Frank   Bokeloh’s      account    suffered      unauthorized
    withdrawals totaling $19,000 during the first two days of April
    1997.   The bank’s computer records showed that Merhan had examined
    Bokeloh’s account information for approximately six minutes on 21
    March 1997, although no teller transaction involving the account
    occurred that day.
    Merhan and Serrano were also charged with being involved in a
    bank larceny,   for   which   Calvin   arranged    a   staged    robbery   at
    Merhan’s branch.   Merhan told police that, after arriving at work
    at 7:00 a.m. on 16 May 1997, two individuals approached his vehicle
    and forced him at gunpoint to enter the bank and de-activate the
    - 3 -
    alarm; that the robbers instructed him not to enter the “duress
    code”, a secret number for a robbery in progress alert, which the
    robbers knew was 1790; that, after telling the robbers that he did
    not know both sets of numbers needed to open the main vault, they
    told him they knew he had the complete combination and forced him
    to open it; that the robbers then bound him and took approximately
    $392,000 from the vault; and that he was able to free himself and
    call the police.
    Those involved in the “robbery” testified, however, that it
    was staged using inside information from Merhan.          Calvin testified
    that Merhan provided him with information regarding the bank’s
    operating procedures, the location of alarms and cameras, the alarm
    codes,   and   the   cash   shipment   schedule,   and   also   gave   him   a
    schematic drawing of the inside of the branch.            Calvin had then
    recruited several accomplices.
    Calvin also testified that, shortly before the staged robbery,
    he alerted Serrano, who then contacted Merhan. Telephone records
    confirmed that, during the period before the staged robbery, Merhan
    made several calls to Calvin and Serrano.
    Tuyen Vi Chau, known as “Richard”, one of the “robbers” who
    approached Merhan while he was in his vehicle, testified that he
    understood that the teller was a participant in the “robbery”; that
    - 4 -
    it was staged; and that, although he did not know the insider’s
    name, Calvin had told him that the insider was a Filipino who drove
    a white Civic hatchback.   Both characteristics fit Merhan.
    Following the staged robbery, the accomplices divided the
    stolen money.   Later that day, Calvin met Serrano and handed him a
    shoe box with $60,000 in cash for him to deliver to Merhan as his
    share of the proceeds.   Following the larceny, Serrano spent large
    amounts of cash, including purchasing two airline tickets to Hong
    Kong costing approximately $9,000.
    A few months after the “robbery”, Merhan and Serrano, along
    with numerous others, were charged with conspiracy to commit bank
    fraud and bank larceny (count I), bank fraud (counts II and III),
    entering with intent to commit bank larceny (count IV), bank
    larceny (count V), and receiving stolen money (count VI).
    Following a jury trial, Merhan and Serrano were convicted for
    conspiracy (count I), Merhan for bank fraud (count II), and Serrano
    - 5 -
    for receipt of stolen money (count VI); each was acquitted on the
    other counts.    Merhan’s sentence included 57 months in prison and
    $432,000   in   restitution;    Serrano’s,   46   months   in   prison   and
    $464,000 in restitution.
    II.
    A.
    Serrano first contests the denial of his motion to suppress
    evidence seized during a search of his apartment and automobile,
    claiming that his written consent was not voluntary.             As he was
    leaving his apartment in August 1997, he was arrested by a Houston
    police officer.     FBI Agents soon arrived and obtained written
    consent for the search.
    To be valid, consent must be both free and voluntary.              E.g.,
    United States v. Kelley, 
    981 F.2d 1464
    , 1470 (5th Cir. 1993).            “The
    government has the burden of proving, by a preponderance of the
    evidence, that the consent was voluntary.”        
    Id. This is
    a question
    of fact to be “determined from the totality of the circumstances
    surrounding the search”.       United States v. Morales, 
    171 F.3d 978
    ,
    982 (5th Cir. 1999) (citing Schneckloth v. Bustamonte, 
    412 U.S. 218
    , 227 (1973)).
    For   this,    six   factors    must    be   considered:    “(1)    the
    voluntariness of the defendant’s custodial status; (2) the presence
    - 6 -
    of coercive police procedures; (3) the extent and level of the
    defendant’s    cooperation   with    the    police;   (4)    the   defendant’s
    awareness of his right to refuse to consent; (5) the defendant’s
    education and intelligence; and (6) the defendant’s belief that no
    incriminating evidence will be found”.           
    Id. We review
    a post-
    hearing denial of a suppression motion under a “particularly
    strong” clearly erroneous standard, because the judge was able to
    observe the witnesses.       
    Kelley, 981 F.2d at 1470
    (quoting United
    States v. Sutton, 
    850 F.2d 1083
    , 1086 (5th Cir. 1988)).
    Of course, that Serrano was in custody when he gave his
    consent does not ipso facto invalidate it.                  United States v.
    Watson, 
    423 U.S. 411
    , 424 (1976).            At the suppression hearing,
    Serrano claimed that his consent was not voluntary because an FBI
    Agent told him that he would be more likely to make bond if he
    cooperated; the Agent denied making the statement.                   For this
    credibility call, the district court’s ruling was not clearly
    erroneous.
    B.
    Appellants challenge the evidentiary sufficiency for their
    convictions.    For properly preserved sufficiency challenges, we
    will affirm if, when viewing the evidence in the light most
    favorable to the verdict and accepting the credibility choices of
    - 7 -
    the jury, a rational jury could have found that the Government
    proved, beyond a reasonable doubt, the essential elements of the
    charged crime.   E.g., United States v. Guerrero, 
    169 F.3d 933
    , 938
    (5th Cir. 1999) (citing United States v. Pankhurst, 
    118 F.3d 345
    ,
    351 (5th Cir.), cert. denied, 
    118 S. Ct. 630
    (1997)).        Serrano and
    Merhan preserved this standard of review by moving for judgment of
    acquittal at the close of the evidence.         FED. R. CRIM. P. 29(a);
    
    Guerrero, 169 F.3d at 938
    ; 
    Pankhurst, 118 F.3d at 352
    .
    1.
    Merhan first asserts that the evidence is insufficient to
    support his convictions for conspiracy to commit bank fraud (one of
    the two charged objects of the conspiracy; a similar challenge to
    the other object is discussed infra) and for bank fraud.
    a.
    To   establish   a   conspiracy   under   18   U.S.C.   §   371,   the
    Government “must prove beyond a reasonable doubt (1) that two or
    more people agreed to pursue an unlawful objective; (2) that the
    defendant voluntarily agreed to join the conspiracy; and (3) that
    one or more of the members of the conspiracy committed an overt act
    to further the objectives of the conspiracy”.          United States v.
    Campbell, 
    64 F.3d 967
    , 975 (5th Cir. 1995).
    - 8 -
    Merhan asserts that his conspiracy conviction rested primarily
    on Calvin’s testimony, which he claims was insufficient to persuade
    a rational jury of his guilt. In this regard, Merhan maintains that
    numerous other people known to Calvin had ties to the bank and
    could have provided the account information.
    However,   “a   [conspiracy]   conviction   may   rest   on   the
    uncorroborated testimony of an accomplice, even one who has chosen
    to cooperate with the government in exchange for leniency, as long
    as the testimony is not insubstantial on its face”.     United States
    v. Posada-Rios, 
    158 F.3d 832
    , 861 (5th Cir. 1998), cert. denied,
    
    119 S. Ct. 1280
    , 1487, 1792 (1999).    “Testimony is incredible as a
    matter of law only if it relates to facts that the witness could
    not possibly have observed or to events which could not have
    occurred under the laws of nature.”    
    Id. Calvin testified
    that Merhan supplied him with information
    regarding both Loh and Bokeloh’s accounts and that Merhan received
    a share of the unlawfully-obtained money.     Needless to say, this
    testimony is not “insubstantial on its face”.          Moreover, bank
    records demonstrating that Merhan had accessed the Loh and Bokeloh
    accounts, and Jimmy Ngo’s testimony linking Merhan to the fraud,
    corroborate Calvin’s testimony and provide further evidence from
    which a rational jury could find guilt.
    - 9 -
    b.
    Merhan    relies     on   essentially   the     same   bases   for   his
    sufficiency challenge to his bank fraud conviction.            To establish
    such fraud, pursuant to 18 U.S.C. § 1344(1), the Government must
    prove that Merhan “knowingly execute[d], or attempt[ed] to execute,
    a scheme or artifice — (1) to defraud a financial institution; or
    (2) to obtain any of the moneys, funds, ... or other property owned
    by, or under the custody or control of, a financial institution, by
    means   of   false   or   fraudulent    pretenses,    representations,     or
    promises”.    See also    United States v. Schnitzer, 
    145 F.3d 721
    , 734
    (5th Cir. 1998); 
    Campbell, 64 F.3d at 975
    .
    The above-described evidence of Merhan’s involvement in the
    fraud scheme was also sufficient to prove beyond a reasonable doubt
    that he committed § 1344(1) bank fraud.              See United States v.
    Barakett, 
    994 F.2d 1107
    , 1111 (5th Cir. 1993) (“While section
    1344(1) prohibits only crimes directed at financial institutions,
    we have not held that the statute punishes only schemes directed
    solely at institutional victims”); United States v. Church, 
    888 F.2d 20
    , 23 (5th Cir. 1989) (even proof of extremely remote risk of
    loss to bank suffices).
    - 10 -
    2.
    As    noted,    Merhan   also   claims    that    the   evidence     was
    insufficient to sustain a conviction for conspiracy to commit bank
    larceny (the other charged object).           He relies primarily on his
    acquittal on the substantive bank larceny counts.
    This acquittal-based contention is meritless.             Needless to
    say, acquittal on substantive charges does not mandate acquittal on
    a corresponding conspiracy charge.        E.g., United States v. Duvall,
    
    846 F.2d 966
    , 975-76 (5th Cir. 1988).
    Three persons testified that there was an agreement between
    two or more persons to conduct a staged robbery of the branch.
    Calvin testified that Merhan agreed to join the conspiracy and
    provided information to the “robbers”; two other co-conspirators
    testified that they knew Merhan to be the bank “insider” assisting
    in staging the robbery.       And, more than one conspirator committed
    an overt act in furtherance of the conspiracy.                Although the
    evidence   showing   Merhan’s    participation    in   the   conspiracy    is
    primarily accomplice testimony, it is not “insubstantial on its
    face”. 
    Posada-Rios, 158 F.3d at 861
    .
    3.
    Serrano first claims that the evidence did not prove that he
    was linked to the conspiracy, or agreed to assist with the staged
    - 11 -
    robbery, or committed any overt act.              But, Calvin and other co-
    conspirators    testified   that    Serrano   acted     as    an   intermediary
    between Calvin and Merhan during the bank fraud and bank larceny
    schemes; a co-conspirator testified that Serrano met with Calvin
    and Merhan to discuss the staged robbery; and there was evidence
    that Serrano made several large cash expenditures following the
    staged robbery.
    4.
    To sustain a conviction under 18 U.S.C. § 2113(c) for receipt
    of stolen money, Serrano’s other conviction, the Government must
    prove that (1) he “receive[d], possesse[d], store[d], barter[ed],
    [sold], or dispose[d] of” (2) money stolen from a bank (3) with
    knowledge that the money was stolen. See United States v. Buchner,
    
    7 F.3d 1149
    , 1152-53 (5th Cir. 1993) (§ 2113(c) is “intended for
    those persons     who   receive    the   stolen    property    from   the   bank
    robber”).
    Serrano claims that there was insufficient proof that he knew
    the money was stolen from the bank.           But, Calvin testified that
    Serrano assisted him and Merhan in planning the staged robbery; and
    that, after the robbery, he gave Serrano a shoe box containing
    $60,000.    Another co-conspirator testified that Serrano met with
    Merhan and Calvin to discuss the larceny.            Again, this accomplice
    - 12 -
    testimony is not “insubstantial on its face”.           
    Posada-Rios, 158 F.3d at 860
    .
    C.
    Appellants challenge the district court’s multiple mistrial
    denials when the jury indicated it was unable to reach a verdict.
    It sent several notes to the judge along this line.
    On   the   first   day,   the   jurors   advised    that   they   were
    “deadlocked”. Appellants moved for a mistrial. Instead, the judge
    instructed the jurors to resume deliberations the next morning.
    After deliberating for a total of about eight hours, the
    jurors again advised that they were “locked”.           Again, Appellants
    moved for a mistrial.    The district court refused to grant one and
    gave the jury a modified Allen charge.2         Subsequently, the jury
    requested that the testimony of five Government witnesses be read.
    Appellants, once again, moved for a mistrial.       The district court
    instead instructed the jury to designate the portions of testimony
    it wished to have read.
    2
    See Allen v. United States, 
    164 U.S. 492
    , 501-02 (1896) (not
    error for a court to render supplemental instructions to a
    deadlocked jury). The trial judge may remind the jurors of their
    duty to reach a verdict and instruct them to consider the opinions
    of the other jurors. 
    Id. “While, undoubtedly,
    the verdict of the
    jury should represent the opinion of each individual juror, it by
    no means follows that opinions may not be changed by conference in
    the jury room.” 
    Id. at 501.
    - 13 -
    The final note asked:         “If we find one defendant guilty of
    Count 1, part A [conspiracy to commit bank larceny], and the other
    defendant guilty of Count 1, part B [conspiracy to commit bank
    fraud], does this make each defendant guilty of the entire Count
    1?” Urging this indicated that the jurors were seeking a compromise
    verdict, Appellants again moved for a mistrial.                   Instead, the
    district    court    instructed      the       jurors   to    continue    their
    deliberations.
    A mistrial denial is reviewed for abuse of discretion. United
    States v. Sylvester, 
    143 F.3d 923
    , 929 (5th Cir. 1998).               The first
    two denials, which followed jury deadlock notes, were not such
    abuses. When they transmitted the second note, the jurors had been
    deliberating only slightly over eight hours.                 For example, our
    court held that it was not an abuse of discretion to deny a
    mistrial after the jury deliberated for seven days in a complex
    bank fraud trial.        United States v. Heath, 
    970 F.2d 1397
    , 1405-06
    (5th Cir. 1992).         The case against Merhan and Serrano was also
    complex.
    For the third denial, which corresponded to the testimony
    request (written after the Allen charge), Appellants assert that
    the jury note reveals that it interpreted the Allen charge as
    requiring   them    to    start   over   and    surrender    it   conscientious
    - 14 -
    conviction.     The Allen charge specifically instructed the jurors
    not to do so.
    The final denial followed the note regarding the effect of
    convictions.     As before, Appellants maintain that the final two
    notes revealed that the jury was trying to reach a compromise
    verdict by surrendering its conscientious conviction because of a
    coercive Allen charge.        There is no evidence that a juror was
    coerced; instead, the questions are consistent with conscientious
    deliberations    and   the    jury’s    duty   to   render   a   decision   in
    accordance with the law.
    Obviously, a district court has broad discretion to give an
    Allen charge.    United States v. Pace, 
    10 F.3d 1106
    , 1125 (5th Cir.
    1993).    Appellants     do    not     challenge    its   content,   and    the
    circumstances surrounding the charge being given were not coercive.
    
    Heath, 970 F.2d at 1406
    (deviation from approved charges cannot be
    so prejudicial as to require reversal and circumstances must not be
    coercive).    As noted, our court found no abuse of discretion for an
    Allen charge in a complex bank fraud trial where the jury remained
    deadlocked after seven days of deliberation. 
    Id. Likewise, giving
    the Allen charge in this case, after less than two days of
    deliberation, was not an abuse of discretion.
    - 15 -
    D.
    Appellants    challenge     their      sentences   on   several   bases.
    Application of the Sentencing Guidelines is reviewed de novo;
    factual findings, for clear error.              E.g., 
    Sylvester, 143 F.3d at 931
    .   A sentence will be upheld unless it was imposed in violation
    of   law   or   as   a   result   of    an    incorrect   application    of   the
    Guidelines, or if it is outside the range of the applicable
    guideline and is unreasonable.           E.g., United States v. Wyjack, 
    141 F.3d 181
    , 183 (5th Cir. 1998).
    1.
    Merhan claims that he was erroneously sentenced under the
    theft guideline, U.S.S.G. § 2B1.1, rather than the fraud guideline,
    resulting in a higher base offense level.            U.S.S.G. § 1B1.2(d) (“A
    conviction on a count charging a conspiracy to commit more than one
    offense shall be treated as if the defendant had been convicted on
    a separate count of conspiracy for each offense that the defendant
    conspired to commit”); see United States v. Fisher, 
    22 F.3d 574
    ,
    576 (5th Cir. 1994) (Ҥ 1B1.2(d) governs the application of the
    Sentencing Guidelines to multiple-object conspiracies”).
    Merhan acknowledges that, in accordance with § 1B1.2(d), the
    district court found, beyond a reasonable doubt, that bank larceny
    was an object of the conspiracy.             See United States v. Manges, 110
    - 16 -
    F.3d 1162, 1178 (5th Cir. 1997), cert. denied, 
    118 S. Ct. 1675
    (1998) (district court may sentence on more serious of two charged
    conspiracies    if    “district      court   itself       would   have   convicted
    [defendant] on that basis”); United States v. Cooper, 
    966 F.2d 936
    ,
    941 (5th Cir. 1992). He claims, however, insufficient evidence for
    that finding, because he was acquitted of the substantive bank
    larceny charges.      But, as noted, that finding was not precluded by
    the   bank   larceny    acquittal.       See    
    Duvall, 846 F.2d at 975
    (conspiracy and substantive counts are “separate and distinct
    crimes” and “conviction on any count may stand if it is supported
    by the evidence”); United States v. Jackson, 
    167 F.3d 1280
    , 1282
    (9th Cir. 1999) (jury acquittal on substantive offense does not
    prohibit application of § 1B1.2(d) at sentencing); see also 
    Cooper, 966 F.2d at 941
    (§ 1B1.2(d) properly applied where district court
    found object of conspiracy was proven beyond reasonable doubt).3

    Appellants     also   assert    that    this    §   1B1.2(d)   application
    deprived them of their Sixth Amendment right to trial by jury.                  Our
    court has held otherwise.

    Serrano adopts Merhan’s issues presented here. It is unclear
    whether this issue is one he can adopt; assuming he can, it
    likewise fails.

    The    next    challenge      is   to     the    relevant    conduct     used    in
    calculating offense levels. The amount of loss calculation is
    reviewed for clear error.          United States v. Sutton, 
    77 F.3d 91
    , 94-
    95 (5th Cir. 1996).
    Merhan contests the inclusion of the $392,000 loss from the
    bank larceny; Serrano, any amount over the $60,000 he received from
    Calvin.    And, both contend they should not be held accountable for
    funds    related    to   the   substantive       counts     of    which     they   were
    acquitted.    However, the evidence supports the finding that each
    conspired    to    commit   bank    larceny      and     bank    fraud.      The     loss
    calculations were not clearly erroneous.
    4.
    Appellants challenge each base offense level being enhanced by
    two-levels for obstruction of justice, pursuant to U.S.S.G. §
    3C1.1.     We review only for clear error.                E.g., United States v.
    Gray, 
    105 F.3d 956
    , 971 (5th Cir.), cert. denied, 
    520 U.S. 1128
    ,
    1150, 1246 (1997).
    “If    the    defendant    willfully            obstructed    or     impeded,    or
    attempted to obstruct or impede, the administration of justice
    during the investigation, prosecution, or sentencing of the instant
    offense, increase the offense level by 2 levels.”                          U.S.S.G. §
    - 18 -
    3C1.1. Perjury is a type of conduct to which the enhancement
    applies.    U.S.S.G. § 3C1.1 application note 3(b).          If the district
    court finds that a defendant committed perjury at trial, the
    obstruction enhancement is required.           United States v. Gonzalez,
    
    163 F.3d 255
    , 262 (5th Cir. 1999); United States v. Humphrey, 
    7 F.3d 1186
    , 1189 (5th Cir. 1993).
    Merhan and Serrano’s presentence investigation reports (PSRs)
    did not recommend the enhancement.              The Government objected,
    claiming perjury by Merhan at the trial and by Serrano at the
    suppression hearing.
    At    Merhan’s   sentencing,    and     adopted   for   Serrano’s   which
    followed immediately thereafter, the district court stated:
    Counsel [for the Government] cites examples of
    each defendant’s trial testimony that they
    believe is perjurious, in effect, perjury.
    ... The Court sustains this objection and
    finds by a preponderance of the evidence that
    Merhan and Serrano committed perjury during
    their trial testimony; therefore, a two-level
    adjustment for obstruction of justice will be
    given to each defendant.
    (Emphasis added.)
    a.
    Merhan asserts that the court failed to make sufficient
    factual findings; and, in the alternative, that his trial testimony
    - 19 -
    does not support the enhancement. This insufficient findings claim
    is based upon United States v. Dunnigan, 
    507 U.S. 87
    , 95 (1993),
    which    provides     that,    “if   a     defendant     objects    to     a    sentence
    enhancement resulting from her trial testimony, a district court
    must review the evidence and make independent findings necessary to
    establish a willful impediment to or obstruction of justice, or an
    attempt to do the same, under the perjury definition we have set
    out”.    Merhan claims failure to make specific findings that each
    perjury element was satisfied.
    But, a detailed and specific finding on each perjury element
    is not required.       
    Id. (“[I]t is
    preferable for a district court to
    address each element of the alleged perjury in a separate and clear
    finding”    (emphasis    added)).          Rather,      “[t]he    district       court’s
    determination that enhancement is required is sufficient ... if ...
    the court makes a finding of an obstruction of, or impediment to,
    justice that encompasses all of the factual predicates for a
    finding of perjury”.          
    Id. at 94.
    A   witness      commits    perjury      if   he   “gives     false       testimony
    concerning a material matter with the willful intent to provide
    false testimony, rather than as a result of confusion, mistake, or
    faulty     memory”.      
    Id. The district
         court    referenced       the
    Government’s objection, which specifically cited Merhan’s testimony
    - 20 -
    that he did not provide Calvin with information for the bank fraud
    and bank larceny.       The district judge’s statements at sentencing
    and his reference to the Government’s objection reflect a finding
    that Merhan lied when he so testified.            See 
    Gonzalez, 163 F.3d at 263
    (affirming obstruction enhancement where court adopted PSRs and
    “expressly     stated   its   finding      that   each   defendant   perjured
    himself”).
    Of course, perjury requires materiality. Although neither the
    Government’s    objection,    nor    the    district     judge’s   statements,
    specifically address this, our court has upheld similar obstruction
    enhancements where, “[e]ven though there was no explicit finding by
    either the trial or sentencing judge that this testimony was
    material, [the defendant’s] testimony on this topic was obviously
    ‘material’ in that it was clearly ‘designed to substantially affect
    the outcome of the case’”.       United States v. Cabral-Castillo, 
    35 F.3d 182
    , 187 (5th Cir. 1994); see United States v. Como, 
    53 F.3d 87
    , 90 (5th Cir. 1995); United States v. Storm, 
    36 F.3d 1289
    , 1297
    (5th Cir. 1994).    Likewise, it is obvious that Merhan’s identified
    statements went to the very heart of the case against him and were
    designed to affect the verdict.
    Merhan challenges finding his statements perjurious; but, as
    
    demonstrated supra
    , that finding was not clearly erroneous.               See
    - 21 -
    
    Dunnigan, 507 U.S. at 95-96
    (“Given the numerous witnesses who
    contradicted respondent regarding so many facts on which she could
    not have been mistaken, there is ample support for the District
    Court’s finding.”); United States v. Laury, 
    985 F.2d 1293
    , 1309
    (5th Cir. 1993).
    b.
    The Government, for sentencing, claimed perjury by Serrano at
    the suppression hearing when he “unequivocally testified [1] that
    the officers and agents who arrested him and searched his apartment
    and automobile did not advise him of his right to refuse to consent
    to the searches and [2] that he did not consent thereto”. But,
    regarding the right to refuse, Serrano did not so testify; instead,
    he testified that he was informed of that right.   At oral argument
    on appeal, the Government corrected its error.
    Serrano maintains that the second part of the Government’s
    objection – that he testified he did not give consent – is also
    incorrect because he testified that he did sign the consent form.
    The Government agrees that Serrano did testify in that limited
    respect, but maintains that the objection more broadly refers to
    his testimony that consent was not given voluntarily.       As the
    Government points out, the issue at the suppression hearing was not
    - 22 -
    whether Serrano gave consent; it was whether that consent was
    voluntary.
    We agree with the Government’s interpretation.               The same
    district   judge    presided   over    the   suppression   and   sentencing
    hearings; he was aware that Serrano had given written consent, but
    had testified that it was not voluntary.        Also, the district judge,
    as noted, found that both defendants had committed perjury.             See
    
    Gonzalez, 163 F.3d at 263
    .
    Further,      the   Government’s    objection    to   Serrano’s    PSR
    specifically addressed materiality, noting that, had the district
    court credited Serrano’s suppression hearing testimony, a large
    amount of evidence would have been suppressed and the Government’s
    case weakened substantially.          Therefore, the district judge, by
    reference to the objection, made sufficient findings to support the
    obstruction enhancement.4
    4
    At oral argument, Serrano claimed yet another reason why the
    perjury finding was not supported by the record — his testimony
    could have been the result of mistake. However, Serrano’s brief
    challenges only the sufficiency of the stated bases for the
    findings.    Normally, issues raised for the first time at oral
    argument will not be addressed. E.g., Whitehead v. Food Max of
    Mississippi, Inc., 
    163 F.3d 265
    , 270 (5th Cir. 1998); United States
    v. Miles, 
    10 F.3d 1135
    , 1137 n.3 (5th Cir. 1993), cert. denied, 
    118 S. Ct. 1201
    (1998). The necessity for this rule is obvious. This
    contention is not an exception to it.
    - 23 -
    5.
    Next,    Merhan     challenges   his       enhancement      for   abuse    of   a
    position of trust: “If the defendant abused a position of public or
    private    trust,   or    used   a   special      skill,    in    a    manner    that
    significantly facilitated the commission or concealment of the
    offense, increase [the offense level] by 2 levels”.                     U.S.S.G. §
    3B1.3.    According to the commentary, however, the adjustment does
    not “apply in the case of embezzlement or theft by an ordinary bank
    teller”.     U.S.S.G. § 3B1.3, application note 1.               “The application
    of § 3B1.3 is a sophisticated factual determination reviewed under
    the clearly erroneous standard.”            United States v. Fisher, 
    7 F.3d 69
    , 70 (5th Cir. 1993).
    The PSR (adopted by the district court) recommended the
    enhancement.     In response to Merhan’s objection, the probation
    officer stated that Merhan’s behavior “in the bank larceny scheme
    went beyond that of a mere teller” because he “provided the
    security     sensitive     information          regarding     the      bank     vault
    combination, [schematic] drawing of the facility[,] and security
    codes to the co-conspirators”.
    We must examine “the extent to which [Merhan’s] position
    provides   the   freedom    to   commit     a    difficult-to-detect          wrong”.
    United States v. Brown, 
    7 F.3d 1155
    , 1161 (5th Cir. 1993) (quoting
    - 24 -
    United   States     v.   Hill,   
    915 F.2d 502
    ,   506   (9th    Cir.   1990)).
    Generally, ordinary bank tellers do not occupy a position of trust
    because, “although the teller’s position provides an opportunity to
    embezzle money, reasonably diligent supervisors could easily detect
    the wrongdoing after it has occurred”.              
    Id. Unlike an
    ordinary bank teller, Merhan was responsible for
    opening the bank each morning; he knew the security codes; and the
    bank gave him part of the combination to the main vault.                       See
    
    Fisher, 7 F.3d at 70
    (head cashier occupied position of trust
    because she supervised another, could get money out of vault and
    requisition money, and had only monthly spot checks). Further, his
    supervisor trusted him with the rest of the combination.                    See 
    id. (noting that
    it was significant that defendant’s supervisor stopped
    conducting spot checks because of her trust in defendant).                   These
    factors placed him in a position of trust.                See also United States
    v.   Gordon,   
    61 F.3d 263
    ,       268   (4th   Cir.     1995)   (enhancement
    appropriate where defendant, who was head teller with access to
    security codes, facilitated armed robbery of bank); United States
    v. Hathcoat, 
    30 F.3d 913
    , 919 (7th Cir. 1994) (“In determining
    whether the defendant’s position was a position of trust, we must
    analyze the situation from the perspective of the victim”).
    - 25 -
    Additionally, Merhan’s position significantly contributed to
    the facilitation of the staged robbery.               He provided his co-
    conspirators with information regarding the dates of money drops at
    the bank, the security codes, the opening procedures, and the
    bank’s interior floor plan.       Further, he unlocked the bank door,
    disarmed the security system, and opened the vault for his co-
    conspirators on the day of the larceny.               See United States v.
    Johnson, 
    4 F.3d 904
    , 916 (10th Cir. 1993) (vault teller’s position
    facilitated bank robbery where she instructed others how to rob
    bank and avoid detection and handed the money to the robber).
    6.
    Appellants    contest    their     §   5K2.6   upward    departures   for
    possession of a firearm by one of the co-conspirators during the
    bank larceny.    Decisions to depart upward are reviewed for abuse of
    discretion.     Koon v. United States, 
    518 U.S. 81
    , 91 (1996).
    Appellants     first    contend    that    the   trial    evidence    was
    insufficient to support the statement in the PSR that a firearm was
    used during the staged robbery.         However, they do not demonstrate
    that the statement was erroneous; Merhan testified at trial that
    one of the “robbers” put a firearm to his head; and both state in
    their briefs that one of the “robbers” had a gun.              Additionally,
    one of the “robbers” initially told investigators that one of the
    - 26 -
    co-conspirators had a firearm during the staged robbery.    Merhan
    and Serrano have failed to show that the information in the PSR
    relating to the use of a weapon is materially untrue.   See United
    States v. Davis, 
    76 F.3d 82
    , 84 (5th Cir. 1996) (district court may
    credit evidence for sentencing purposes that has “some indicia of
    reliability”) (quoting United States v. Shacklett, 
    921 F.2d 580
    ,
    585 (5th Cir. 1991)).
    Appellants also claim that the district court’s findings were
    insufficient for us to review the propriety of the departure.5
    “Before a departure is permitted, certain aspects of the case must
    be found unusual enough for it to fall outside the heartland of
    cases in the Guideline.”   
    Koon, 518 U.S. at 98
    ; see also United
    States v. McDermott, 
    102 F.3d 1379
    , 1384 (5th Cir. 1996). The
    district court did not specifically discuss why the firearm took
    this case out of the heartland of the typical bank larceny case.
    Section 5K1.0 states that “this subpart seeks to aid the court
    by identifying some of the factors that the Commission has not been
    able to take into account fully in formulating the guidelines”.   At
    5
    Merhan also asserts, once again, that he should not be held
    responsible for the firearm use because he was acquitted of the
    substantive bank larceny charges. As noted, that acquittal does
    not relieve him of liability as a co-conspirator in the bank
    larceny.
    - 27 -
    § 5K2.6, the Commission identified the use of a weapon as one of
    those factors:
    If a weapon or dangerous instrumentality was
    used or possessed in the commission of the
    offense the court may increase the sentence
    above the authorized guideline range.      The
    extent of the increase ordinarily should
    depend on the dangerousness of the weapon, the
    manner in which it was used, and the extent to
    which its use endangered others....6
    Thus, the Guidelines acknowledge that they do not adequately take
    into account the use of a firearm in all offenses, and that this is
    a proper ground for departure.    Therefore, the Guidelines state
    that use of a firearm takes a case out of the heartland of typical
    cases; and the district judge’s reference to § 5K2.6 is sufficient
    to support the decision to depart.     See United States v. Lee, 
    989 F.2d 180
    , 183 (5th Cir. 1993) (“The Sentencing Commission permits
    courts to depart from the guidelines where weapons are used in the
    commission of an offense, see U.S.S.G. § 5K2.6, because such an
    aggravating circumstance has not been given adequate consideration
    by the guidelines”); United States v. Register, 
    931 F.2d 308
    , 314
    (5th Cir. 1991) (“This court has upheld upward adjustments for mere
    possession of a firearm”) (citing United States v. Otero, 
    868 F.2d 6
           Our court has interpreted § 5K2.6 as referring “to crimes
    that may be committed with or without the use of a weapon”. United
    States v. Medina-Gutierrez, 
    980 F.2d 980
    , 983 (5th Cir. 1992).
    - 28 -
    1412, 1414 (5th Cir. 1989); United States v. Hewin, 
    877 F.2d 3
    , 5
    (5th Cir. 1989); United States v. Mueller, 
    902 F.2d 336
    , 345 (5th
    Cir. 1990)).
    In addition to referencing § 5K2.6, the district court gave
    specific reasons for the extent of the departure, including its
    concern that an innocent bystander could have interrupted the
    staged robbery and been injured.     These reasons are adequate; we
    find no abuse of discretion in the extent of the departure.     See
    
    Lee, 989 F.2d at 183
    (§ 5K2.6 departure will be upheld if extent is
    reasonable; district court not required to give specific or general
    reasons for extent).
    7.
    Finally, Serrano asserts that, because he was acquitted of the
    substantive bank fraud counts, the district court erroneously
    included in his $464,000 restitution (Merhan’s is for $432,000) the
    $32,000 taken from a bank other than Wells Fargo.     In any event,
    consistent with his loss calculation claim, he contends that he
    should not be ordered to repay an amount greater than the $60,000
    he received after the staged robbery.
    As discussed, the evidence was sufficient to find that Serrano
    conspired in both bank fraud and bank larceny.      Concerning the
    - 29 -
    other bank, the district court relied properly on the PSR.             The
    restitution amount was not clearly erroneous.
    III.
    In   the   light   of   the    foregoing,   Merhan   and   Serrano’s
    convictions and sentences are
    AFFIRMED.
