    April 9, 2003
    LIPEZ,   Circuit      Judge.          On    April    23,     2001,    a    jury
    convicted Luis Rivera Newton ("Rivera Newton", a.k.a. "Luis el
    Mono,"      "Luisito")   of     conspiracy          to    possess       with     intent    to
    distribute in excess of five kilograms of cocaine, more than one
    kilogram of heroin, and multiple kilograms of marijuana.                                   On
    October 12, 2001, the district court sentenced Rivera Newton to
    life imprisonment.          Rivera Newton now appeals his conviction on
    three      grounds:      1)   the    district            court    improperly       admitted
    statements of co-conspirators, 2) the district court erroneously
    excluded evidence of his prior acquittal in state court for a
    multiple      homicide   that    formed      an      integral          component    of    the
    government's conspiracy case, and 3) his attorneys labored under an
    impermissible      conflict     of   interest.             He    also     challenges      his
    sentence, claiming that the district court erroneously calculated
    his offense level under the United States Sentencing Guidelines
    (the       "Guidelines").       Finding        no    merit        in    Rivera     Newton's
    contentions, we affirm the defendant's conviction and decline to
    set aside his sentence.

    We describe the facts in the light most favorable to the
    verdict.      United States v. Diaz,

    , 69 (1st Cir. 2002).1
    The evidence at trial described Rivera Newton's involvement in a

    We recount facts here to convey a general picture of the
    case, and provide additional detail in subsequent sections where it
    is relevant to the legal analysis.
    -2-
    "hub-and-spoke conspiracy"2 to distribute multi-kilogram quantities
    of cocaine, heroin, and marijuana from the early months of 1989 to
    April 8, 1998.         The drugs were sold at specialized distribution
    points for each substance ("drug points") primarily located within
    the Gautier Benitez Housing Project ("Gautier Benitez") in Cagua,
    Puerto Rico.       While the drug points were managed by different
    individuals,     every    distribution    point    in   Gautier   Benitez   was
    ultimately controlled by Edsel Torres Gomez (a.k.a. "Negri"), the
    de facto "hub" of the conspiracy.                 At trial, the government
    portrayed Rivera Newton as Negri's right-hand man and presented
    witnesses who testified to Rivera Newton's role as a conduit
    between Negri and lower-level members of the conspiracy.                Negri
    also       entrusted     Rivera   Newton     with       various    high-level
    responsibilities such as counting the money received in drug
    transactions and testing the quality of the drugs purchased from
    other dealers.
    Rivera Newton's claims of error implicate, inter alia,
    the testimony of co-conspirators who served as "spokes" of the
    conspiracy.     Several of these individuals were among the seven co-
    defendants indicted with Rivera Newton on June 2, 1999.              Of these
    2
    In a "hub-and-spoke conspiracy," a central mastermind, or
    "hub," controls numerous "spokes," or secondary co-conspirators.
    These co-conspirators participate in independent transactions with
    the individual or group of individuals at the "hub" that
    collectively further a single, illegal enterprise. See Kotteakos
    v. United States, 
    328 U.S. 750
    , 754-55 (1946).
    -3-
    seven, six pled guilty in exchange for reduced sentences and agreed
    to testify against Rivera Newton at trial.                      The seventh co-
    defendant,     Francisco   Fernandez         Rios    ("Fernandez        Rios")    also
    testified against Rivera Newton in exchange for a reduction in his
    sentence for a previous conviction.                 Their varying roles in the
    conspiracy and the substance of the testimony at issue in this
    appeal   are   best    understood     in   the      context   of    the   two    major
    activities undertaken by the conspiracy -- trafficking drugs and
    protecting Negri's drug empire.
    A.           Drug Trafficking
    The government's first witness was Javier Perez Alicea
    ("Perez Alicea"), a drug supplier who testified that from 1993 to
    1995 he sold approximately 200 kilograms of cocaine to a close
    confidant of Negri named Jimmy Peligro.                  Perez Alicea conveyed
    these drugs to Peligro through approximately 20 to 25 transactions,
    and Peligro in turn arranged for the cocaine to be sold at the
    appropriate drug points in Gautier Benitez.               Perez Alicea further
    testified that Rivera Newton participated in three or four of these
    transactions, helping Peligro and Perez Alicea to count the money
    being exchanged and testing the quality of the cocaine.
    Fernandez Rios, the government's next witness, was the
    main supplier of drugs to Negri's organization. Beginning in 1992,
    he   sold    between   1,500    and    1,600        kilograms      of   cocaine    and
    approximately 1,000 pounds of marijuana to Negri directly and to an
    -4-
    associate    of    Negri   named   Yuco.      Most   of   these     drugs    were
    distributed to drug points managed by Rivera Newton in Gautier
    Benitez, although Negri also wholesaled some of the drugs to drug
    points controlled by other traffickers.
    The third drug supplier to testify for the government was
    Cesar Escobar Vazquez ("Cesar Escobar").           Cesar Escobar supplied a
    total of two kilograms of heroin to Negri's organization for resale
    in Gautier Benitez,3       and from June to July 1994 he also sold 2 to
    3 kilograms of heroin to a drug dealer named "Davey."             Davey rented
    a drug point from Negri in Barriada Morales and was one of the two
    victims in the "Isla Verde murders" discussed below.
    B.          Protecting Negri's Drug Empire
    During the period covered by the indictment, various
    members of the conspiracy took steps to eliminate threats to
    Negri's drug empire.       Of particular relevance to this case are two
    multiple    murders    that   were    committed    in   furtherance     of    the
    conspiracy.       The first murders, referred to at trial as the "Isla
    Verde    murders,"    eliminated     Davey   and   another   drug    dealer    in
    retaliation for their unauthorized encroachment on Negri's drug
    points.     Perez Alicea testified that he was supplying drugs in
    October 1994 to an individual named Wes Solano who, according to
    3
    While Negri primarily operated out of Gautier Benitez,
    various drug suppliers testified that Negri also controlled a
    limited number of drug points in two other housing projects --
    Villa Del Ray and Barriada Morales.
    -5-
    appellant, was "the head of one of Puerto Rico's most extensive and
    violent drug organizations."       Solano frequented an apartment that
    Perez Alicea rented in the Isla Verde area.                At one point he
    arranged for Negri, Jimmy Peligro, and Cano Newton (Rivera Newton's
    brother) to conduct surveillance from the apartment to determine
    whether Davey and the second drug dealer were infringing on Negri's
    drug points.       After confirming his suspicions, Solano and an
    accomplice killed the two drug dealers the next day. Later, Solano
    justified the killings to Perez Alicea as the elimination of two
    individuals     who   "were   trying    to   outsmart    Negri   with   regard
    to . . . certain drug points."
    The second multiple murder, dubbed the "Cayey Massacre"
    by the Puerto Rico press, was the brutal torture and murder of four
    individuals who supposedly stole $4.2 million in drug proceeds that
    Negri   had    temporarily    stored    at   Fernandez   Rios's   residence.
    Fernandez Rios testified that avenging this theft was particularly
    important for Negri not only to recover the money itself, but also
    because "the loss of that money had to be justified in the eyes of
    the Colombians" who supplied drugs to Negri and were presumably
    concerned with the security of his operation.
    On March 13, 1994, Negri informed Perez Alicea that he
    had kidnaped the four individuals who committed the robbery.               One
    of the individuals was shot and killed immediately, and Rivera
    Newton helped direct the interrogation of the other three. Negri's
    -6-
    associates tortured the three individuals by tearing out their
    fingernails, burning them with acid, and forcing them to drink
    gasoline.   They then threw the accused thieves in the back seat of
    a car, where they were shot and set on fire.        Rivera Newton's
    participation in the Cayey Massacre was a central issue at trial,
    and ultimately an aggravating factor that led the district court to
    sentence him to life imprisonment, the maximum sentence permitted
    by the Guidelines.
    II.
    A.          Hearsay Statements Admitted Under Rule 801(d)(2)(E)
    Rivera Newton claims that the district court erroneously
    admitted two groups of hearsay statements under Rule 801(d)(2)(E)
    of the Federal Rules of Evidence: 1) statements made by Solano to
    Perez Alicea describing the Isla Verde murders, and 2) statements
    made by Prieto Capota, described at trial as "Negri's triggerman,"
    to Cesar Escobar concerning the Cayey Massacre and Isla Verde
    murders.
    Federal Rule of Evidence 801(d)(2)(E) excludes from the
    category of hearsay "statement[s] by a coconspirator of a party
    during the course and in furtherance of the conspiracy."    Fed. R.
    Evid. 801(d)(2)(E).    As a predicate for admitting evidence under
    this rule, the trial court must conclude that "it is more likely
    than not that the declarant and the defendant were members of a
    conspiracy when the hearsay statement was made, and that the
    -7-
    statement was in furtherance of the conspiracy."             United States v.
    Petrozziello, 
    548 F.2d 20
    , 23 (1st Cir. 1977).                  In our circuit,
    this   determination     is    referred    to   as   a   Petrozziello    ruling.
    Significantly, the trial court is not required to decide the
    Petrozziello question prior to admitting hearsay statements under
    Rule 801(d)(2)(E), but may "admit the statement[s] provisionally,
    subject to its final Petrozziello determination at the close of all
    the evidence."      United States v. Isabel, 
    945 F.2d 1193
    , 1199 n.10
    (1st Cir. 1991).       Hence, to properly preserve an objection to a
    Petrozziello ruling, a defendant must ordinarily object both when
    the hearsay statements are provisionally admitted and again at the
    close of all the evidence.
    Generally, "we review the trial court's determination
    that statements were coconspirator statements under the clear error
    standard."      United States v. Marino, 
    277 F.3d 11
    , 25 (1st Cir.
    2002) (citing United States v. Mojica-Baez, 
    229 F.3d 292
    , 304 (1st
    Cir. 2000)).       This deferential standard of review places a heavy
    burden   on    a   defendant    seeking    to   overturn    a    trial   court's
    Petrozziello ruling:
    A finding is clearly erroneous when although
    there is evidence to support it, the reviewing
    court on the entire evidence is left with the
    definite and firm conviction that a mistake
    has been committed.    Where the evidence is
    susceptible of two plausible interpretations,
    the trier of fact's choice between them cannot
    be clearly erroneous.
    -8-
    Reich v. Newspapers of New England, Inc., 
    44 F.3d 1060
    , 1080 (1st
    Cir. 1995) (internal quotation marks and citations omitted).4
    Applying this standard, we consider the two hearsay statements
    challenged by Rivera Newton.
    1.     Statements made by Solano to Perez Alicea
    describing the Isla Verde murders
    Perez Alicea, one of Negri's drug suppliers, testified
    over the defendant's objections to a conversation he had with
    Solano about the Isla Verde murders.      According to Perez Alicea,
    Solano told him that the Isla Verde victims were murdered because
    "they were trying to get away with certain things at some of the
    drug points that belonged to Negri." Rivera Newton claims that the
    court's decision to admit this statement was clear error for two
    reasons: 1) the court had no basis for concluding that Solano (the
    declarant) and Rivera Newton were co-conspirators, and 2) assuming
    arguendo that Solano and Rivera Newton were co-conspirators, the
    hearsay   statements   could   not   logically   have   been   made   "in
    furtherance of the conspiracy," Petrozziello, 
    548 F.2d at 23
    ,
    4
    The parties dispute whether our review should be governed by
    the even more deferential plain error standard, in light of Rivera
    Newton's conceded failure to renew his objection to the court's
    Petrozziello determination at the close of all the evidence.
    Rivera Newton argues that his persistent, standing objections to
    the court's admission of hearsay testimony throughout the trial
    cured any defect arising from his failure to object yet again after
    all of the evidence was submitted. Because we conclude that the
    trial court did not commit clear error in admitting the hearsay at
    issue, we do not reach the question of whether the trial court's
    Petrozziello ruling should only be subject to review for plain
    error.
    -9-
    because they were made after the commission of the Isla Verde
    murders.
    We turn first to the question of whether the district
    court clearly erred in determining that Solano and Rivera Newton
    were co-conspirators.     The defendant points us to United States v.
    Sepulveda, 
    15 F.3d 1161
     (1st Cir. 1993), in which we held that "a
    coconspirator's statement, standing alone, is insufficient to meet
    the preponderance standard of Rule 801(d)(2)(E) . . . [A]dmitting
    the statement into evidence requires some extrinsic proof of the
    declarant's involvement in the conspiracy."         
    Id. at 1181
    .    Rivera
    Newton argues that the government was therefore "required to show,
    by   some   independent   evidence,   that   [he]   was   related   to   the
    conspiracy to kill two people in Isla Verde, and the existence of
    a conspiracy between [him] and . . . Wes Solano."
    This   argument   construes   the   relevant conspiracy too
    narrowly.    We observed in United States v. Martinez-Medina, 
    279 F.3d 105
     (1st Cir. 2002), that
    each coconspirator need not know of or have
    contact with all other members, nor must they
    know all of the details of the conspiracy or
    participate in every act in furtherance of it.
    The [finder of fact] may infer an agreement
    circumstantially by evidence of, inter alia, a
    common purpose (such as a purpose to sell
    illicit drugs), overlap of participants, and
    interdependence of various elements in the
    overall plan.
    
    Id. at 113-14
    ; see also Marino, 
    277 F.3d at 25
     ("As long as it is
    shown that a party, having joined a conspiracy, is aware of the
    -10-
    conspiracy's features and general aims, statements pertaining to
    the details of plans to further the conspiracy can be admitted
    against   the   party   even   if   the   party   does   not    have     specific
    knowledge of the acts spoken of.") (internal citations omitted).
    Here, the jury convicted Rivera Newton for broadly conspiring "to
    knowingly and intentionally possess with the intent to distribute"
    large quantities of illicit drugs.            The indictment specified that
    the object of this conspiracy was so (sic)
    that the defendants and their co-conspirators
    would earn money illicitly in and through drug
    trafficking and other drug related activities.
    The manner and the means by which the unlawful
    conspiracy was accomplished included the
    following . . . . [The conspirators] would []
    contract killers that would be hired . . . to
    intimidate and kill rival gang members and to
    maintain   and   stabilize   control  of   the
    organization's drug distribution points.
    The evidence at trial highlighted the importance of the Isla Verde
    murders in furthering the objectives of this larger conspiracy to
    earn money for Negri's drug organization through the illicit
    traffic of narcotics -- a conspiracy to which Rivera Newton was
    undoubtedly     a   party,   viewing    the   evidence   in    the    light   most
    favorable to the verdict.       See Diaz, 
    300 F.3d at 69
    .            Accordingly,
    the validity of the district court's Petrozziello ruling does not
    turn on the narrow question of whether Rivera Newton conspired in
    the commission of the Isla Verde murders.           To uphold the district
    court's Petrozziello ruling under a clear error standard we need
    only confirm that the evidence at trial permitted the trial judge
    -11-
    to conclude that Solano and Rivera Newton were co-conspirators in
    the broader drug trafficking conspiracy.
    Even setting the disputed statements to one side, see
    Sepulveda,    
    15 F.3d at 1181
    ,   Perez   Alicea's   testimony     could
    reasonably have led the district court to conclude that Solano
    participated in the drug trafficking conspiracy by helping to
    eliminate individuals who encroached on Negri's drug points. Perez
    Alicea testified at length to an encounter with Negri and several
    other individuals in October 1994.          Negri had obtained the keys to
    an apartment in Isla Verde that Perez Alicea rented and shared with
    Solano, and Negri's associates asked Perez Alicea for the location
    of "the apartment that Wes [Solano] had."           After Perez Alicea led
    them to the apartment, Jimmy Peligro, one of Negri's associates,
    made phone calls in an effort to locate Solano.            The other members
    of Negri's party began surveillance of the apartment next door to
    Perez Alicea, discussing at one point how the individuals within
    the apartment were "really going to be fucked" once Solano showed
    up.   Perez Alicea further testified that the next day, Negri's
    associates confirmed that they had made contact with Solano; within
    the next three to five days Solano revealed to Perez Alicea in the
    conversation at issue that he had committed the Isla Verde murders.
    Perez Alicea's     uncontradicted       testimony   describing   the   period
    immediately    preceding       the   Isla   Verde   murders   supports     the
    interpretation that Solano participated in the broad conspiracy
    -12-
    outlined in the indictment.           Accordingly, the trial court did not
    clearly err in determining that Rivera Newton and Solano were co-
    conspirators within the meaning of Rule 801(d)(2)(E).
    Rivera     Newton's      alternative         argument     that    Solano's
    comments    about     the    Isla    Verde    murders     did   not    "further     the
    objectives   of      the    conspiracy"      is    similarly    unavailing.         The
    defendant argues that an after-the-fact description of the Isla
    Verde murders could not have furthered the objective of eliminating
    individuals who by that time were already dead.                     Once again, this
    argument construes the relevant "objective" of the conspiracy too
    narrowly.    The Petrozziello requirements are satisfied so long as
    Solano's act of communicating the motivation behind the murders and
    the manner      in   which    they    were    committed      furthered       the   broad
    objectives of the drug trafficking conspiracy.                  In this instance,
    Solano, who the appellants concede "acted, at times, as a hired gun
    for   Negri,"    was   informing       a    major    drug   supplier     to    Negri's
    organization that he had committed a multiple murder to protect
    Negri's drug points from unauthorized use.                  The trial court could
    reasonably   have      determined      that       this   conversation    served      the
    important function of reassuring Perez Alicea that Negri's drug
    organization was effectively addressing external threats to its
    security and profitability.           See United States v. Ammar, 
    714 F.2d 238
    , 252 (3d Cir. 1983) ("Statements between the conspirators which
    provide reassurance, serve to maintain trust and cohesiveness among
    -13-
    them, or inform each other of the current status of the conspiracy
    further the ends of the conspiracy and are admissible so long as
    the other requirements of Rule 801(d)(2)(E) are met.").5
    2.     Statements made by Prieto Capota to Cesar Escobar
    concerning the Cayey Massacre and Isla Verde
    murders
    Approximately one month after the Cayey Massacre, Prieto
    Capota recounted in detail the torture and murder of the four Cayey
    victims during a conversation with Cesar Escobar, another of
    Negri's drug suppliers.   At trial, Cesar Escobar repeated Prieto
    Capota's description of the Cayey Massacre to the jury.    Although
    the defendant concedes that he and Prieto Capota (the declarant)
    were co-conspirators within the meaning of Rule 801(d)(2)(E), he
    argues that the statements are nonetheless inadmissible for two
    reasons:   1) the statements did not further the objectives of the
    conspiracy as required by Petrozziello, and 2) the statements were
    unduly prejudicial and should have been excluded under Rule 403.
    Once again, in light of Rivera Newton's failure to raise the Rule
    5
    Rivera Newton also claims, belatedly, that the trial court
    should have excluded this portion of Perez Alicea's testimony on
    grounds that its probative value was outweighed by its prejudicial
    effect. Fed. R. Evid. 403. Because Rivera Newton never raised
    this objection below, we review for plain error only.       United
    States v. Balsam, 
    203 F.3d 72
    , 85-86 (1st Cir. 2000). Applying
    this highly deferential standard, we do not find that the trial
    court's decision to admit this testimony under Rule 403 was an
    error "so shocking [as to] seriously affect the fundamental
    fairness and basic integrity of the proceedings conducted below."
    United States v. Griffin, 
    818 F.2d 97
    , 100 (1st Cir. 1987).
    -14-
    403 objection below, we review the trial court's decision to admit
    Cesar Escobar's testimony under Rule 403 for plain error, and apply
    a    clear   error    standard   to    the   trial   court's   Petrozziello
    determination.       These claims of error are indistinguishable from
    Rivera Newton's Petrozziello and Rule 403 arguments challenging the
    admission of Perez Alicea's testimony, and we reject them for the
    reasons outlined above.6
    B.           The Exclusion of Rivera Newton's Acquittal on State
    Murder Charges Stemming from the Cayey Massacre
    Prior to trial, the government filed a motion in limine
    to prohibit Rivera Newton from alluding to his previous acquittal
    in state court on murder charges stemming from the Cayey Massacre.
    The district court granted the motion, relying, inter alia, on our
    prior decisions specifying that "a district court has discretion to
    exclude from evidence acquittals or other favorable outcomes of
    prior state court proceedings involving the same subject matter."
    United States v. Marrero-Ortiz, 
    160 F.3d 768
    , 775 (1st Cir. 1998);
    6
    Rivera Newton cursorily raises Petrozziello and Rule 403
    claims challenging the trial court's admission of other testimony
    from Cesar Escobar regarding 1) an argument between Negri and
    Davey, one of the Isla Verde victims, and 2) Cesar Escobar's
    conversations with an ex-partner and a car dealer in which he was
    told that Davey had been killed at Isla Verde. "[I]ssues adverted
    to in a perfunctory manner, unaccompanied by some effort at
    developed argumentation, are deemed waived."      United States v.
    Zannino, 
    895 F.2d 1
    , 17 (1st Cir. 1990). Even if Rivera Newton had
    not abandoned these arguments on appeal, we would have no cause to
    reverse the district court's decision to admit this testimony under
    the plain error standard of review occasioned by appellant's
    failure to raise contemporaneous objections to these statements
    below.
    -15-
    see also United States v. Smith, 
    145 F.3d 458
    , 462 (1st Cir. 1998).
    Citing Federal Rule of Evidence 403, the judge also concluded that
    "the probative value of the acquittals is substantially outweighed
    by the danger of unfair prejudice."
    Although Rivera Newton does not challenge the district
    court's authority to grant the motion in limine, he argues that the
    prosecution took unfair advantage of the trial court's ruling by
    repeatedly referring to the fact that he had been charged with the
    Cayey murders, knowing that he could not dispel the prejudice
    arising from those references by introducing the fact of his
    acquittal.   As a threshold matter, both parties misrepresent the
    extent to which the government referred to Rivera Newton's state
    murder   charges.   The   defendant    alleges   that   the   prosecution
    "allowed the fact of the prior trial to permeate its evidence,"7
    while the government retorts that "[a]t no time during trial were
    appellant's charge, arrest or acquittal mentioned."           In fact, our
    7
    This misstatement perhaps reflects the appellant's efforts to
    conflate testimony concerning the Cayey Massacre itself with
    testimony referring to the state murder charges brought against
    Rivera Newton in the aftermath of the incident. The government
    matter-of-factly concedes in its brief that the former was a major
    element of their case, asserting that "the Cayey Massacre proved to
    be this violent organization's way to recuperate millions of
    dollars in drug proceeds stolen from them, and a way to demand
    respect from non-members." We agree with the government that the
    introduction of evidence pertaining to Rivera Newton's acquitted
    conduct did not preclude the judge from excluding the fact of
    Rivera Newton's acquittal. United States v. Candelaria-Silva, 
    166 F.3d 19
    , 35 (1st Cir. 1999); Smith, 
    145 F.3d at 462
     (1st Cir.
    1998).
    -16-
    review of the record reveals a single instance in which the
    government elicited a reference to Rivera Newton's state murder
    trial.   During the prosecution's direct examination of Antonio
    Garay Fonseca, a longtime acquaintance of Rivera Newton, the
    following exchange occurred:
    Q:       I ask you, sir, have you ever heard about what is
    known as the Cayey massacre?
    A:       Yes.
    Q:       How is it that you, yourself find out?              Where
    were you when you found out?
    A:       I was in jail here in the prison in Guaynabo.
    Q:       And I ask you, sir, now, have you ever discussed
    the event of the Cayey massacre with Luis El Mono
    [Rivera Newton]?
    A:       Yes, on several occasions.
    Q:       Can you please tell us what was the contents of
    that conversation?
    A:       Well, I asked him how his case, the case
    involving the massacre was coming along.
    Rivera Newton argues that the court erred by failing sua
    sponte to alleviate the prejudice from this exchange in one of two
    ways: 1) the court could have rescinded its ruling in limine and
    permitted Rivera Newton to "present the other half of the story" by
    introducing the fact of his acquittal, or 2) the court could have
    expressly instructed the jury not to consider the state murder
    charges as     evidence   of   Rivera   Newton's   guilt   on   the   federal
    indictment.    Because Rivera Newton did not ask the trial court to
    -17-
    rescind its earlier ruling excluding evidence of his acquittal or
    give the aforementioned jury instruction, we review the errors
    alleged for plain error.            Garay Fonseca's reference to Rivera
    Newton's state prosecution for murder, occurring within the context
    of a nine-day trial that generated over nine hundred pages of trial
    testimony,   did    not   require    the   court   to   reverse   its   earlier
    decision to exclude evidence of Rivera Newton's acquittal or
    provide a curative jury instruction.           The former remedy presented
    an unwarranted risk of confusing the jury, while the latter would
    likely have attracted more attention to the state murder charges
    than Garay Fonseca's remark.         In any event, this reference was not
    "so   shocking     that   [it]   seriously     affect[ed]   the   fundamental
    fairness and basic integrity of the proceedings conducted below."
    Griffin, 
    818 F.2d at 100
    .
    Rivera Newton also draws our attention to a second
    reference to his state murder charges elicited by his own lawyers
    over the government's objection.             Jose Quiñonez Robles, the FBI
    agent assigned to Rivera Newton's case, was asked by defense
    counsel during cross-examination whether he was aware that Rivera
    Newton had no criminal record.             After the court overruled the
    government's objection to the question, Quiñonez responded: "Yes,
    I know that he was accused in the local system for participating in
    the Cayey massacre."        Pressed further, Quiñonez clarified that
    Rivera Newton had only been accused of murder at the state level,
    -18-
    and that to his knowledge the defendant did not have a criminal
    record.
    Quiñonez's evasive response to defense counsel's question
    regarding Rivera Newton's criminal record is disturbing.               As an
    experienced FBI agent, he presumably understood the difference
    between a criminal record and a criminal charge, and his answer was
    clearly not responsive to defense counsel's inquiry.        Nonetheless,
    the defense did not move to strike Quiñonez's testimony. Arguably,
    his reference to the state charges even benefitted the defense.
    There had already been a reference to the state case in the earlier
    testimony of Garay Fonseca.        Quiñonez's subsequent mention of the
    state accusations permitted Rivera Newton's counsel to extract the
    concession that, to the witness's knowledge, Rivera Newton had no
    criminal record, thereby prompting a possible inference by the jury
    that Rivera Newton was acquitted of the state charges. Regardless,
    we find no error, let alone plain error, in the trial court's
    failure to instruct the jury sua sponte to disregard the statement.
    C.         Conflict of Interest
    Three days before the beginning of Rivera Newton's trial,
    the government alerted the district court to information obtained
    from Fernandez Rios, a government witness, regarding arrangements
    by Negri's drug organization to finance the legal defense of Rivera
    Newton    and   other   criminal     defendants    associated   with     the
    organization in prior state proceedings.          Specifically, Fernandez
    -19-
    Rios revealed during an interview that after several members of
    Negri's drug organization were indicted in March 1995 on state
    murder charges stemming from the Cayey Massacre, he informed a
    Colombian drug source named "Mauricio" that the Cayey defendants
    needed financial assistance for their legal defense.           Mauricio
    agreed to send Fernandez Rios forty kilograms of cocaine to pay for
    their legal expenses, and Fernandez Rios subsequently arranged to
    sell the cocaine in the United States for approximately $20,000 per
    kilogram. The proceeds from this drug shipment were turned over to
    Ramon Delgado ("Bronco"), an attorney who was closely associated
    with Negri.   While Fernandez Rios could not identify the attorneys
    who received money from Bronco, he had reason to believe that Edgar
    Vega-Pabón,   one   of   Rivera   Newton's   attorneys   in   the   state
    proceedings, and now one of his attorneys in this federal case, may
    have been paid from this drug fund for defending an individual
    named Ismael Vega in another case.       However, the government had no
    direct evidence that Bronco paid Vega-Pabón to defend Rivera
    Newton, or that José Andreu, Rivera Newton's other trial attorney
    in this case, ever received money from Bronco.      In fact, during the
    colloquy between the court and attorneys from both sides that
    followed the government's presentation of these facts, Vega-Pabón
    denied that he had ever knowingly received funds from Bronco.
    According to Rivera Newton, the fact that his attorneys
    may have been compensated through Bronco's legal defense fund
    -20-
    created a possible conflict of interest for the following reason:
    if Vega-Pabón and Andreu feared that Fernandez Rios would expose
    them as beneficiaries of Bronco's legal defense fund, they may have
    tempered their cross-examination of a crucial witness for the
    government.8      Alerted   to   the    possibility    of   a   conflict,   the
    district court questioned Rivera Newton to ensure 1) that he was
    aware of the potential conflict of interest, 2) that his attorneys
    had explained the relevant circumstances to him, and 3) that he
    nonetheless wished to retain Andreu and Vega-Pabón as defense
    counsel.    After hearing the court recite the information conveyed
    earlier    by   the   government,   Rivera    Newton   confirmed    that    his
    attorneys had previously discussed the matter with him, and assured
    the court that he wanted them to continue as counsel.                  Rivera
    Newton now claims on appeal, however, that the court's failure to
    more fully explain how this conflict of interest could manifest
    itself at trial constitutes reversible error under the Sixth
    Amendment: "[F]aced with these troubling assertions, [the court]
    had a duty to describe or illustrate why Appellant might prefer to
    have counsel not likely to be distracted by the threat that
    8
    Rivera Newton articulates the gravity of the conflict more
    colorfully in his Reply Brief, arguing that "Andreu was virtually
    precluded from cross-examining Fernandez, lest Fernandez accuse him
    of knowing receipt of drug proceeds (at a minimum) from the witness
    stand.   Indeed, Andreu's mere presence at counsel table was a
    liability for Appellant because the jury might well infer that his
    role was to represent the interests of the conspiracy."
    -21-
    [Fernandez Rios] would persist in his allegations [that counsel had
    been compensated by Bronco]."
    The defendant's claim of error is styled somewhat oddly.
    He expressly disclaims any argument that the trial court's failure
    to adequately explain the potential conflict of interest induced
    him   to   retain   counsel   who   rendered     ineffective    assistance,
    specifying that "[r]ather than an ineffective assistance claim,
    Appellant has raised only the narrow issue of the legal sufficiency
    of the District Court's colloquy to determine whether Appellant was
    aware of a potential conflict of interest with his attorney and
    wished to waive it" (emphasis added).            Put another way, Rivera
    Newton argues that the trial court's failure to describe adequately
    the conflict of interest constitutes reversible error requiring a
    new   trial,   irrespective   of    the    quality   of   defense   counsels'
    performance: "[I]t is the failure to explain the nature of the
    conflict that would allow Appellant to make an intelligent waiver,
    not any specific trial error, that requires this court's remedial
    attention."
    The circumstances of this case provide no basis for
    overturning a conviction on Sixth Amendment grounds absent any
    allegation by the defendant that the performance of defense counsel
    suffered as a result of the alleged conflict.                In Mickens v.
    Taylor, 535 U.S. __, 
    122 S.Ct. 1237
     (2002), the Supreme Court
    expressly rejected a rule of automatic reversal in cases where a
    -22-
    defense attorney's conflict of interest does not adversely affect
    counsel's performance, observing that such a rule "makes little
    policy sense."        
    Id. at 1244
    .    The Court elaborated that a trial
    court's failure to adequately investigate a potential conflict of
    interest
    neither renders it more likely that counsel's
    performance was significantly affected nor in
    any other way renders the verdict unreliable.
    Nor does the trial judge's failure to make the
    Sullivan-mandated inquiry9 [] make it harder
    for reviewing courts to determine conflict and
    effect, particularly since those courts may
    rely   on   evidence   and   testimony   whose
    importance only becomes established at the
    trial.
    
    Id.
            Because   adverse   performance   is   the   touchstone   of   Sixth
    Amendment error under the Supreme Court's actual conflict-of-
    interest jurisprudence, Mickens, 
    122 S.Ct. at
    1244 n.5, Rivera
    Newton's argument for per se reversal on grounds that the judge
    inadequately explained the nature of the particular conflict is at
    odds with controlling Supreme Court precedent.10
    9
    In Cuyler v. Sullivan, 
    446 U.S. 335
     (1980), the Supreme Court
    promulgated a rule requiring trial courts to conduct an inquiry if
    they "know or reasonably should know" that defense counsel is
    laboring under a conflict of interest. 
    Id. at 347
    .
    10
    Our decision in United States v. Foster, 
    469 F.2d 1
     (1st Cir.
    1972), relied upon heavily by Rivera Newton, does not permit
    automatic reversal here. In Foster, we exercised our supervisory
    powers to require district courts to explain to defendants in
    detail the risks of proceeding to trial "where one attorney speaks
    for two or more defendants." 
    Id. at 4-5
    . However, this rule, now
    codified as Federal Rule of Criminal Procedure 44(c), is expressly
    limited to cases of joint or multiple representation, 
    id. at 4
    , a
    circumstance that does not exist on the facts before us.
    -23-
    D.          The District Court's    Calculation   of Rivera Newton's
    Offense Level
    Applying sections 2D1.1 and 2A1.1 of the United States
    Sentencing Guidelines, the district court sentenced Rivera Newton
    to life imprisonment, the maximum sentence permitted under the
    Guidelines.    The court predicated its sentence on two alternative
    Guidelines calculations, either one of which, standing alone,
    mandated the imposition of a life sentence.       First, applying the
    "murder cross reference" provision of U.S.S.G. § 2D1.1(d)(1), the
    court determined by a preponderance of the evidence that Rivera
    Newton's role in the Cayey Massacre warranted a base offense level
    of 43.    After adding a three-level enhancement for Rivera Newton's
    leadership role in the conspiracy and a two-level enhancement for
    possession of a weapon during the course of the offense, the court
    calculated a total offense level of 48.11   Alternatively, the court
    attributed to Rivera Newton responsibility for distributing in
    excess of 150 kilograms of cocaine, resulting in a base offense
    level of 38.    U.S.S.G. § 2D1.1(c)(1).   The court increased Rivera
    Furthermore, under Foster, violations of this rule do not trigger
    automatic reversal, but merely shift the burden of persuasion to
    the government "to demonstrate from the record that prejudice to
    the defendant was improbable." Id. at 5. Here, the government
    would easily satisfy this burden in the absence of any allegation
    by Rivera Newton that he was prejudiced by defense counsel's
    performance at trial.
    11
    As the district court noted, "the guidelines do not go above
    43." Accordingly, any offense level of 43 or above is punishable
    by a life sentence.
    -24-
    Newton's offense level under this second calculation to 43 after
    adding five points for leadership and possession of a weapon.
    Hence, Rivera Newton was subject to life imprisonment under either
    sentencing calculation.
    On   appeal,     Rivera   Newton   challenges     both    Guidelines
    calculations on three grounds: 1) the court violated his due
    process rights by applying U.S.S.G. § 2A1.1 after finding by a
    preponderance of the evidence that he had participated in the Cayey
    Massacre, 2) the court unreasonably attributed to Rivera Newton
    responsibility for the entire quantity of drugs handled by Negri's
    organization, and 3) the court erroneously concluded that Rivera
    Newton was a leader in the drug conspiracy.           We find no reversible
    error in the district court's application of the murder cross-
    reference provision of section 2D1.1(d)(1), which alone results in
    a   base   offense   level    of   43.    Accordingly,      we   do   not   reach
    appellant's      claims    implicating       the   district      court's    drug
    calculation and three-level leadership enhancement.
    1.   Legal analysis
    Section 2D1.1 is the provision of the Guidelines that
    governs the sentencing of defendants like Rivera Newton convicted
    of "Unlawful Manufacturing, Importing, Exporting or Trafficking;
    Attempt or Conspiracy." Subsection (d) of this provision, entitled
    "Cross References," provides the following: "If a victim was killed
    under circumstances that would constitute murder under 18 U.S.C.
    -25-
    § 1111 had such killing taken place within the territorial or
    maritime jurisdiction of the United States, apply § 2A1.1 (First
    Degree Murder)." Section 2A1.1 of the Guidelines, in turn, directs
    the court to assign a base offense level of 43 to any defendant
    whose conduct falls within the provision.          The district court
    invoked § 2A1.1 in calculating defendant's sentence, determining
    that "although he did not participate directly in the actual
    killing [of the Cayey Massacre victims], certainly he was part of
    the planning, he was there . . . . He participated in the torturing
    after these three individuals had been kidnaped at a distance from
    Gautier Benitez."
    We   review   the   district   court's   application   of   a
    particular sentencing guideline de novo.      United States v. Padro
    Burgos, 
    239 F.3d 72
    , 76 (1st Cir. 2001).       Appellant argues that
    there is an element of unfairness in the district court's decision
    to impose a sentence at the upper end of the guideline range for
    conduct that Rivera Newton was previously acquitted of in state
    court.   Nonetheless, as Rivera Newton concedes, the law as it
    currently stands affords us no basis for overturning his sentence
    on due process grounds.       As we observed in United States v.
    Lombard, 
    72 F.3d 170
     (1st Cir. 1995):    "A sentencing court may . .
    . consider relevant conduct of the defendant for purposes of making
    Guidelines determinations, even if he has not been charged with --
    and indeed, even if he has been acquitted of -- that conduct, so
    -26-
    long as the conduct can be proved by a preponderance of the
    evidence."       
    Id. at 176
     (original emphasis).
    Our post-Apprendi jurisprudence provides no succor to the
    defendant.       In Apprendi v. New Jersey, 
    530 U.S. 466
     (2000), the
    Supreme Court ruled that "any fact that increases the penalty for
    a crime beyond the prescribed statutory maximum must be submitted
    to a jury, and proved beyond a reasonable doubt."                     
    Id. at 490
    (emphasis added).       Our decisions following Apprendi emphasize that
    district court judges have broad latitude to make factual findings
    that vary a defendant's sentence within the prescribed statutory
    range.   Indeed, in United States v. Martinez-Medina, 
    279 F.3d 105
    (1st Cir. 2002), we rejected an Apprendi argument nearly identical
    to Rivera Newton's challenge in this case.                 The defendants in
    Martinez-Medina similarly attempted to overturn life sentences on
    grounds that "the sentencing court violated Apprendi by finding,
    under a preponderance of the evidence standard, that they played a
    role in various conspiracy murders, thus subjecting them to life
    imprisonment."       
    Id. at 122
    .      There we noted that "[t]he argument
    fails . . . because Apprendi does not apply to findings made for
    purposes    of    the   sentencing     guidelines,     such    as   the    court's
    determination      that    the     appellants   were    accountable       for   the
    murders."    
    Id.
    However,      Rivera    Newton    now   requests   that   we    expand
    Apprendi to require juries to find beyond a reasonable doubt that
    -27-
    the defendant committed murder before the sentencing court is
    permitted to apply the "cross-reference" provision of section
    2D1.1(d)(1).    We decline this invitation to expand Apprendi, as we
    have on prior occasions:
    We . . . decline the appellant's invitation to
    expand the Apprendi rule . . . . Giving
    [Apprendi   its]   plain   meaning,  sentence-
    enhancing facts still may be found by the
    judge under a preponderance-of-the-evidence
    standard as long as those facts do not result
    in a sentence that exceeds the original
    statutory maximum. Indeed, the Apprendi Court
    itself commented that nothing in the history
    of criminal jurisprudence suggests that it is
    impermissible    for    judges   to   exercise
    discretion in imposing a judgment within the
    range prescribed by statute.
    United States v. Robinson, 
    241 F.3d 115
    , 121 (1st Cir. 2001)
    (internal quotation marks omitted) (original emphasis).
    2.   Factual findings
    Rivera Newton further contends that the district court's
    application of U.S.S.G. § 2D1.1(d)(1) was not supported by a
    preponderance of the evidence.          We review the factual findings
    underlying   the   district   court's     application   of   a   particular
    sentencing guideline for clear error.         Padra Burgos, 
    239 F.3d at 76
    .   The court heard eyewitness testimony from William Del Valle-
    Caraballo, a resident of the Gautier Benitez housing project, who
    observed Rivera Newton holding a .38 caliber nickel-plated pistol
    the night before the Cayey Massacre during a meeting with Negri and
    other members of the drug trafficking organization.          The next day,
    -28-
    Del Valle observed three individuals with bloodstained clothing as
    they were pulled out of a car and taken behind a neighboring
    building.        Del   Valle    further     testified   that    after   the   three
    individuals were brought back to the car, Rivera Newton raised and
    lowered a red gasoline can with a white spout as if he were
    spraying gasoline inside the vehicle.
    Much of Del Valle's testimony was corroborated by Cesar
    Escobar, who testified that he was told by Prieto Capota that the
    Cayey victims were thrown into the back seat of a car, forced to
    drink gasoline, and then executed and set on fire.                Finally, Garay
    Fonseca, Negri's long-time acquaintance, testified that Rivera
    Newton admitted to committing the murders:
    Q:         Sir, I ask you, did there ever come a time when
    the defendant, Luis El Mono, admitted to you what
    was his participation in the massacre of Cayey?
    A:         Yes.
    Q:         And what did he admit to you?
    A:         Well, his words, he said that he killed them.
    In the face of this evidence, we find no clear error in the
    district    court's      decision     to    invoke    section    2D1.1(d)(1)     in
    assigning the defendant a base offense level of 43.

    Notwithstanding defense counsel's vigorous efforts on
    Rivera Newton's behalf throughout this appeal, our close review of
    the   record     reveals       no   error   that     warrants   overturning     the

    conviction or sentence.   Accordingly, the judgment of the district
    court is affirmed.
    So ordered.
