    Before RIPPLE, ROVNER and WILLIAMS, Circuit Judges.
    RIPPLE, Circuit Judge. Guy J. Westmoreland was indicted
    on five counts of a six-count multi-defendant indictment.
    He was charged with: causing the death of a person
    through use of a firearm during a drug trafficking crime;
    use of interstate commerce facilities to commit murder
    for hire; conspiracy to commit murder for hire; tamper-
    ing with a witness by committing murder; and causing
    the death of a witness through use of a firearm. On June
    28, 2001, a jury found Mr. Westmoreland guilty on all five
    counts.
    2                                                No. 01-3870
    Mr. Westmoreland previously had been convicted of
    1
    conspiracy to distribute a controlled substance. On Octo-
    ber 25, 2001, the district court imposed sentences with
    respect to both convictions. Mr. Westmoreland was sen-
    tenced to 240 months’ imprisonment on the previous drug
    conviction and to a term of life imprisonment without
    the possibility of parole on counts 2-6 of the later con-
    viction. On October 26, 2001, Mr. Westmoreland filed a
    timely notice of appeal from his second conviction. For
    the reasons set forth in the following opinion, we affirm
    the judgment of the district court.
    I
    BACKGROUND
    Beginning in the spring of 1997, Mr. Westmoreland was
    a partner of Richard Abeln (“Abeln”) in a drug distribu-
    tion business. The two confederates used Abeln’s plane
    to import nine kilograms of cocaine and about ninety
    pounds of marijuana from Texas to a small airport in
    Illinois. In early January 1998, they were arrested for the
    murder of Abeln’s wife, Debra Abeln. Some months before,
    Abeln had decided to terminate his marriage; but, because
    he did not wish to split the assets of his $17 million truck-
    ing business with his wife, he decided to have her killed.
    A few months later, Mr. Westmoreland happened to men-
    tion that he could have someone killed for $1,000. Abeln
    approached Mr. Westmoreland about such a possibility;
    after initially declining, Mr. Westmoreland agreed. Abeln
    testified that, to encourage Mr. Westmoreland to partici-
    pate in the scheme, he had told Mr. Westmoreland that
    1
    This earlier conviction was affirmed by this court in United
    States v. Westmoreland, 
    240 F.3d 618
    , 637 (7th Cir. 2001).
    No. 01-3870                                              3
    his wife had discovered their drug business and was go-
    ing to inform law enforcement authorities.
    Mr. Westmoreland recruited Deandre Lewis (“Lewis”) to
    commit the murder. Abeln and Mr. Westmoreland agreed
    that the murder would occur on December 27, 1997, at a
    local airport and that it would be staged as a robbery
    gone bad. Lewis drove to the airport in a blue Dodge pick-
    up truck provided by Mr. Westmoreland. On the pretext
    of changing a plane part, Abeln drove his wife to the
    airport; their twelve-year-old son, Travis, accompanied
    them. Upon their arrival, Lewis approached the car, de-
    manded Mrs. Abeln’s jewelry, then pulled her from the
    car and fired two shots from a double-barreled shotgun
    into her chest. She died at the scene.
    At the time of the murder, Mr. Westmoreland was on
    vacation with his family in Florida; but, upon his return,
    he helped Lewis dispose of the jewelry. After his arrest
    on January 6, 1998, Mr. Westmoreland directed the de-
    struction of evidence from his jail cell, including the re-
    moval of marijuana from a pinball machine at the West-
    moreland’s house. Tr.VIII at 135. Mr. Westmoreland’s wife
    and sister proceeded to remove the drugs and destroy
    cocaine packaging. 
    Id. at 137-39.
    Additionally, Mr. West-
    moreland ordered his wife to arrange for the destruction
    of the murder vehicle, the blue Dodge pick-up truck,
    which directions his wife followed by having the truck
    crushed. 
    Id. at 140-44.
    II
    DISCUSSION
    In this appeal, Mr. Westmoreland asks that we review
    several evidentiary issues that arose in the course of the
    proceedings in the district court.
    4                                                  No. 01-3870
    A.
    The district court admitted Mr. Westmoreland’s state-
    ment to his wife, Bronnie Matthews, that he had supplied
    2
    Abeln with the phone number of a hit-man. The court
    based its ruling on the Government’s representation
    that Mr. Westmoreland had repeated the statement to his
    parents and therefore the marital communications privi-
    lege was not applicable. Ms. Matthews later testified that
    her husband had not repeated the statement. Conse-
    quently, Mr. Westmoreland moved to strike the previous-
    ly admitted statement and further moved for a mistrial.
    The district court denied the motions on the ground that
    the statement was admissible under the “joint participant”
    exception to the marital privilege.
    We review the trial court’s resolution of a marital privi-
    lege issue for an abuse of discretion. United States v. Lea,
    
    249 F.3d 632
    , 641 (7th Cir. 2001). The marital commun-
    ications privilege is well-established in the federal courts.
    See Blau v. United States, 
    340 U.S. 332
    , 333-34 (1951). As
    early as its decision in Stein v. Bowman, 38 U.S. (13 Pet.) 209,
    223 (1839), the Court set forth the rationale that animates
    the privilege:
    This rule is founded upon the deepest and soundest
    principles of our nature. Principles which have grown
    out of those domestic relations, that constitute the
    basis of civil society, and which are essential to the
    enjoyment of that confidence which should subsist
    between those who are connected by the nearest and
    2
    At the time of the alleged events, Mr. Westmoreland was
    married to Bronnie Westmoreland. They subsequently divorced,
    and Mrs. Westmoreland married Brad Matthews, changing
    her name to Bronnie Matthews. See Tr.VIII at 21-24.
    No. 01-3870                                                      5
    dearest relations of life. To break down or impair the
    great principles which protect the sanctities of hus-
    band and wife, would be to destroy the best solace
    of human existence.
    The basic principles that govern the application of the
    privilege are well-settled in this circuit. See 
    Lea, 249 F.3d at 641
    . Although the “cost of [this] privilege is a reduction
    in truthful disclosure,” our society places a higher value
    on “uninhibited communication between spouses.” 
    Id. The privilege
    can be asserted by either spouse and applies
    to statements made in confidence by one spouse to an-
    3
    other during a valid marriage. 
    Id. Because the
    marital communications privilege places a
    limitation on truthful disclosure, we have recognized an
    exception to the privilege when spouses are joint partici-
    pants in the underlying offense. See United States v. Short, 
    4 F.3d 475
    , 478 (7th Cir. 1993). The reason for this limitation
    is straightforward. “[W]e do not value criminal collusion
    between spouses, so any confidential statements concern-
    3
    There are two clearly recognized marital privileges: the marital
    testimonial privilege and the marital communications privilege.
    Mr. Westmoreland’s contention concerns the latter. Distinct dif-
    ferences exist between the purposes of the two privileges.
    The testimonial privilege looks forward with reference to
    the particular marriage at hand: the privilege is meant to
    protect against the impact of the testimony on the marriage.
    The marital communications privilege in a sense, is broad-
    er and more abstract: it exists to ensure that spouses gen-
    erally, prior to any involvement in criminal activity or a
    trial, feel free to communicate their deepest feelings to each
    other without fear of eventual exposure in a court of law.
    United States v. Lofton, 
    957 F.2d 476
    , 477 (7th Cir. 1992) (quoting
    United States v. Byrd, 
    750 F.2d 585
    , 590 (7th Cir. 1984)).
    6                                                 No. 01-3870
    ing a joint criminal enterprise are not protected by the
    privilege.” 
    Id. Other circuits
    similarly have held that
    conversations about ongoing or future criminal activity that
    the spouses are undertaking jointly are not protected by
    the marital communications privilege. See United States
    v. Ammar, 
    714 F.2d 238
    , 257 (3d Cir. 1983) (collecting cases).
    In this case, Mr. Westmoreland revealed his participa-
    tion in the murder before his wife undertook any actions
    4
    that made her an accessory-after-the-fact. Mr. Westmore-
    land submits that, when the communication is made to the
    spouse before the spouse joins in the criminal activity, the
    marital privilege ought to shield the communication, at
    least when, as here, the spouse later becomes a mere
    accessory-after-the-fact and not a participant in the un-
    derlying crime. We have not had occasion to decide this
    precise issue.
    We turn to the decisions of our colleagues in circuits
    that have dealt with similar situations. The Second Circuit
    has considered whether the marital communications priv-
    ilege should apply to a statement made in confidence to
    a spouse who later became an accessory-after-the-fact.
    See United States v. Estes, 
    793 F.2d 465
    , 466 (2d Cir. 1986).
    As in our case, in Estes, the defendant spouse had in-
    formed his wife that he had participated in criminal activ-
    ity. The Second Circuit held that this statement was not
    made in the course of ongoing joint criminal conduct. See
    
    id. Until that
    communication was made to her, reasoned
    4
    The Government does not argue before us that Ms. Matthews
    was a member of the drug conspiracy, that the murder of Ms.
    Abeln was in furtherance of that conspiracy and that the state-
    ments in question were made to Ms. Matthews in the course
    of that conspiracy.
    No. 01-3870                                                7
    the court, the defendant’s wife did not know that an il-
    legal act had taken place. “The communication to her of
    that knowledge was a necessary precursor to her involve-
    ment and therefore could not have been made as part of
    an ongoing joint criminal activity.” 
    Id. Notably, the
    court
    contrasted this initial statement with later conversations
    that took place after the wife had begun to participate in
    the criminal activity as an accessory-after-the-fact. These
    later conversations, opined the Second Circuit, would not
    be privileged. See 
    id. at 467.
       The Tenth Circuit, addressing the same issue in United
    States v. Neal, 
    743 F.2d 1441
    (10th Cir. 1984), appears to
    have concluded that the marital communications priv-
    ilege does not apply to a spouse who “actively partici-
    pated as an accessory-after-the-fact.” 
    Id. at 1446.
    Although
    the contours of the court’s holding are not entirely clear,
    it appears that the court took the view that later conver-
    sations and acts that took place when the spouses were
    engaged in joint criminal activity would bring the earlier
    initial conversation into the coverage of the exclusion. 
    Id. at 1446-47.
       In Short, we suggested, albeit in dicta, that the approach
    of the Second Circuit was most compatible with the pur-
    poses of the marital communications privilege. Now-
    Chief Judge Flaum wrote that the privilege well “might . . .
    protect disclosures made before the spouse becomes a
    joint participant in the crime” by aiding and abetting the
    principal. 
    Short, 4 F.3d at 479
    ; see also 
    Ammar, 714 F.2d at 258
    (noting that, although the marital testimonial priv-
    ilege is designed to protect the marriage at the time of
    trial, the marital communications privilege attaches at the
    time the communication is made). He pointed out that
    the privilege is intended to preserve the confidentiality of
    the marital relationship at the time the communication
    8                                                No. 01-3870
    is made. “Just as a marital communications privilege con-
    tinues to protect pre-divorce disclosures by an ex-spouse,
    so might the privilege protect disclosures made before
    the spouse becomes a joint participant in the crime.” 
    Short, 4 F.3d at 479
    . The approach set forth in Short has met with
    the approval of scholarly commentary. “The more carefully
    reasoned decisions distinguish between the initial dis-
    closure, as to which the listening spouse is not a joint
    participant, and the later activities by which the second
    spouse may join the criminal enterprise.” 3 Weinstein’s
    Federal Evidence § 505.11 [2][c] (2d ed. 2002); see also 2
    Christopher B. Muller & Laird C. Kirkpatrick, Federal
    Evidence § 207 (2d ed. 1994) (indicating that the “excep-
    tion does not apply to communications made before both
    spouses have become involved in the criminal activity”).
    Given the purpose of the privilege for marital commun-
    ications, we think that the approach foreshadowed in
    Short is the correct one. The initial disclosure of a crime
    to one’s spouse, without more, is covered by the marital
    communications privilege. If the spouse later joins the
    conspiracy, communications from that point certainly
    should not be protected. This distinction is consistent with
    the purpose of the marital communications privilege. As
    one treatise has suggested, further expansion of the
    partners-in-crime exception to the marital privilege could
    “eventually reduce the marital communications privilege
    to a hollow shell.” 25 Charles Alan Wright & Arthur R.
    Miller, Federal Practice and Procedure § 5601 (1989).
    We emphasize that, in reaching this decision, we do
    not, because we need not, confront the situation faced by
    the Court of Appeals for the Fourth Circuit in United
    States v. Parker, 
    834 F.2d 408
    (4th Cir. 1987). There, Justice
    Powell, sitting by designation, held that the marital com-
    munications privilege did not apply to “statements made
    No. 01-3870                                             9
    in the course of successfully formulating and commenc-
    ing joint participation in criminal activity.” 
    Id. at 413.
    When the initial discussion of the past criminal endeavor
    is part of the solicitation and agreement of the spouse
    to participate in the cover-up, reasoned the Justice, the
    policy concerns that implicate the joint criminal partici-
    pation exception are as much implicated as in later com-
    munications made during the criminal activity. 
    Id. Although we
    believe that the district court erred in
    admitting the initial communication between Mr. West-
    moreland and his wife, this misstep does not automatically
    warrant reversal. We have held that, even if evidence
    barred by the marital communications privilege is im-
    properly admitted, we must determine whether the error
    was harmless. See United States v. Short, 
    4 F.3d 475
    , 479
    (7th Cir. 1993). The contested statement constitutes only
    two or three pages of more than 150 pages of the tran-
    script containing Ms. Matthews’ direct testimony against
    her husband. See Tr.VIII at 98-100 (Bronnie Matthews’
    testimony concerning Mr. Westmoreland’s revelation of
    providing a hit-man’s number to Abeln); Tr.VIII at 21-173
    (Bronnie Matthews’ direct testimony); and Tr.IX at 4-208
    (balance of direct and cross). More importantly, the jury
    heard testimony from Mr. Westmoreland’s conspirators,
    Abeln and Lewis, and heard tapes of Mr. Westmore-
    land’s discussing the murder. See Tr.II at 98-99 (Abeln
    testifying that Mr. Westmoreland helped him murder
    his wife); Tr.II at 138-157 (Abeln providing detailed tes-
    timony of Mr. Westmoreland’s participation in develop-
    ing the murder plot); Tr.III at 16-21 (Abeln detailing Mr.
    Westmoreland’s attempts to help him cover up the mur-
    der); Tr.X at 118 (Lewis testifying that he conspired with
    Mr. Westmoreland to murder Debra Abeln); Tr.X at 135-53
    (Lewis’ testimony of Mr. Westmoreland’s direction in plan-
    ning the murder); Tr.XI at 44 (Lewis describing Mr. West-
    10                                               No. 01-3870
    moreland’s assistance in disposing of evidence). In light of
    this evidence, we believe that the error was harmless.
    B.
    The district court admitted the testimony of Chris Sharp’s
    wife, Tammy Sharp. She testified that, after learning of
    Sharp’s involvement in the drug scheme, she had threat-
    ened to go to the police. She further testified that, one
    night, her husband returned to their home covered with
    blood. She further related that her husband had told her
    that he had helped Mr. Westmoreland bury the body of
    an individual who had owed Mr. Westmoreland money
    and who had “talk[ed] too much.” Tr.XI at 232. She also
    testified that she regarded the statement as a personal
    threat.
    Federal Rule of Evidence 801(d)(2)(E) provides that: “A
    statement is not hearsay if . . . [t]he statement is offered
    against a party and is . . . a statement made by a co-conspir-
    ator of a party during the course and in furtherance of the
    conspiracy.” 
    Id. For a
    statement to be admissible under
    Rule 801(d)(2)(E), the Government must prove by a pre-
    ponderance of the evidence that (1) a conspiracy existed;
    (2) the defendant and the person making the statement
    were members of the conspiracy; and (3) the statement
    was made during the course and in furtherance of the
    conspiracy. United States v. Stephens, 
    46 F.3d 587
    , 597 (7th
    Cir. 1995). We review the trial court’s determination un-
    der a clearly erroneous standard. United States v. Stephen-
    son, 
    53 F.3d 836
    , 842 (7th Cir. 1995).
    The statement was properly admitted. The record sup-
    ports the district court’s determination that Sharp was a
    member of the drug conspiracy and that the statement
    No. 01-3870                                               11
    was a threat to Sharp’s wife. We cannot accept Mr. West-
    moreland’s submissions that Sharp was not a member of
    the conspiracy and that the statements were not made in
    furtherance of the conspiracy. The record supports the
    district court’s determination on both of these points. The
    record provides evidence that Mr. Westmoreland paid
    Sharp in drugs and cash to remodel a building for him.
    See Tr.XI at 228-29. Sharp also helped dispose of Mr.
    Westmoreland’s drugs by selling them to others. See
    Tr.VIII at 41; Tr.X at 131-32. Moreover, the statements
    themselves provide evidence that Sharp was a member
    of the conspiracy. The district court was entitled to deter-
    mine that the statements were made in furtherance of
    the conspiracy because, in making them, Sharp intended
    to preserve the conspiracy by frightening his wife in
    order to dissuade her from informing the authorities about
    the drug scheme. See Tr.XI at 232.
    Mr. Westmoreland also submits that the testimony
    should not have been admitted because it was overly
    prejudicial under Federal Rule of Evidence 403. The dis-
    trict court acted well within its discretion in rejecting
    this claim. The testimony supported the Government’s
    theory that Mr. Westmoreland was so committed to the
    drug conspiracy that he would kill in order to maintain
    it. Although the testimony does relate gruesome details,
    it is not overly prejudicial given the context of a trial for
    the murder of a potential witness.
    Finally, we again point out that the record provides a
    significant amount of unchallenged evidence, including
    direct testimony by co-conspirators. Even if Tammy
    Sharp’s testimony was improperly admitted, it was harm-
    less error.
    12                                              No. 01-3870
    C.
    The district court admitted four tapes of incriminating
    conversations between Mr. Westmoreland and Abeln. These
    conversations were initiated by the Illinois State Police
    on a recorded telephone line and implicate Mr. West-
    moreland in the death of Ms. Abeln. State Police Agent
    Freunz Lewis operated the equipment during the calls.
    Agent Lewis died just prior to the commencement of trial.
    Mr. Westmoreland claims that, in the absence of Agent
    Lewis’ testimony, there was an inadequate foundation
    for the admission of the tapes.
    The district court rejected Mr. Westmoreland’s conten-
    tion that the death of the tape recorder’s operator made
    it impossible to lay an adequate foundation for admis-
    sion. It relied upon the testimony of Agents Marty Milko-
    vich and Calvin Dye, which had been admitted in Mr.
    Westmoreland’s earlier drug trial. Agent Milkovich had
    testified that he was present when the calls were made,
    that he had listened in on headphones, and that the
    tapes were “first generation copies” of the tapes made
    that night. Tr.IV at 107. Mr. Westmoreland contends that
    this testimony was insufficient to authenticate the tapes
    and that the court abused its discretion in admitting them
    over his objections.
    We see no basis for concluding that the district court
    abused its discretion in admitting the tapes. In this re-
    spect, we first note that Mr. Westmoreland’s reliance
    upon United States v. Faurote, 
    749 F.2d 40
    (7th Cir. 1984),
    is misplaced. We have rejected the formalistic approach
    of Faurote for the more inclusive approach of Federal Rule
    of Evidence 901(a), which provides: “The requirement of
    authentication or identification as a condition precedent
    to admissibility is satisfied by evidence sufficient to sup-
    port a finding that the matter in question is what its propo-
    No. 01-3870                                                 13
    nent claims.” See Stringel v. Methodist Hosp. of Indiana, Inc.,
    
    89 F.3d 415
    , 420 (7th Cir. 1996) (rejecting formalistic ap-
    proach to admission of tape recordings and noting that
    recollections of eyewitnesses are sufficient) (citations
    omitted). The Government must prove, by clear and con-
    vincing evidence, that the proffered tape is a true, ac-
    curate and authentic recording of the conversation be-
    tween the parties. See Smith v. Chicago, 
    242 F.3d 737
    , 741
    (7th Cir. 2001). In Smith, Judge Bauer, writing for the court,
    stated concisely that the Government may meet this bur-
    den by establishing the tape’s chain of custody or by
    establishing otherwise a foundation as to the trustworthi-
    ness and accuracy of the evidence. He specifically noted
    that the recollection of eyewitnesses was sufficient to
    establish such a foundation. 
    Id. at 742
    (internal quotations
    omitted). The Government clearly submitted sufficient
    evidence to meet its burden here.
    Finally, Mr. Westmoreland suggests that Agent Milko-
    vich’s reference to the tapes as “first generation copies” is
    somehow problematic. However, Federal Rule of Evi-
    dence 1003 provides that a duplicate is admissible to
    the same extent as an original unless there is reason to
    doubt the authenticity or it would be unfair. Even after
    affording himself of the opportunity to have the tape
    tested, Mr. Westmoreland has provided no reason to
    think such circumstances exist.
    The district court reasonably relied upon the eyewit-
    ness testimony of Agents Milkovich and Dye to authen-
    ticate the tapes in the drug trial; consequently, it did not
    abuse its discretion.
    D.
    The district court admitted Government’s Exhibit 118,
    an allegedly false letter, purportedly authored by Bronnie
    14                                                  No. 01-3870
    Matthews and submitted at the sentencing hearing in
    Mr. Westmoreland’s earlier drug trial. The court rea-
    soned that the letter “goes to show a pattern of conduct . . .
    [by] the defendant’s family and the defendant as well.”
    Tr.X at 11. We review this ruling for an abuse of discre-
    tion. United States v. Flores, 
    5 F.3d 1070
    , 1080 (7th Cir. 1993).
    Mr. Westmoreland submits that the letter did not con-
    stitute “relevant evidence” under Federal Rule of Evidence
    401. The Government contends that the letter supported
    its contentions that Mr. Westmoreland’s family sought to
    obstruct justice on numerous occasions by destroying
    items of evidence including marijuana, cocaine packag-
    ing materials, titles to stolen vehicles and the blue Dodge
    pick-up truck used in the murder.
    Although we must give the district court a great deal
    of leeway with respect to determinations about the rele-
    vancy of the evidence, we find it difficult to discern any
    valid basis for the admission of this letter. Although it
    seems well-established that the letter was not written by
    Mr. Westmoreland’s wife, the true author was never
    established and, more importantly, there was no evidence
    that Mr. Westmoreland knew of or even authorized the
    letter when it was presented to the court. Nor is there
    any evidence that the letter was later used by Bronnie
    Matthews to obstruct justice in this case. In light of these
    circumstances, we find it difficult to ascertain any ba-
    sis for the letter’s relevance in this proceeding. At the
    very least, the district court should have ruled the let-
    ter inadmissible under Federal Rule of Evidence 403. The
    5
    prejudicial effect certainly outweighs any probative value.

    Moreover, expert testimony on the issue of the letter’s authen-
    ticity appears to have been collateral to Bronnie Matthews’ tes-
    (continued...)
    No. 01-3870                                                    15
    The Government also submits that, in any event, ad-
    mission of the letter constituted harmless error. In light
    of the significant amount of undisputed evidence of the
    defendant’s guilt, we agree that the admission of a letter
    that, at best, indicated that some individuals associated
    or related to Mr. Westmoreland were attempting to cast
    him in a more favorable light would not have an apprecia-
    ble effect on the jury’s verdict.
    E.
    The Assistant United States Attorney represented in
    her proffer that Lewis would, in the course of his testi-
    mony, mention a trip that he took with Mr. Westmore-
    land and Sharp to collect on a “drug debt” owed to Sharp
    and an intent to pistol whip the debtor. The district court
    rejected Mr. Westmoreland’s argument that this testi-
    mony was admissible only if it conformed to the stric-
    tures of Federal Rule of Evidence 404(b). In the court’s
    view, the proffered evidence was part of the drug conspir-
    acy and not merely “other acts evidence.” Tr.X at 90.
    When Lewis testified about the trip, he failed to refer to
    a “drug debt” or to Mr. Westmoreland’s intent to pistol
    whip the debtor. Tr.X at 132-34. No contemporary objection
    was made by defense counsel.
    We believe that, given the context of the testimony, the
    jury was entitled to infer that Mr. Westmoreland was on
    5
    (...continued)
    timony that she was not the letter’s author. Allowing a handwrit-
    ing expert to corroborate her testimony was impermissible
    under Rule 608(b). Rule 608(b) provides that “[s]pecific instances
    of the conduct of a witness, for the purpose of attacking or
    supporting the witness’ credibility . . . may not be proved by
    extrinsic evidence.” 
    Id. 16 No.
    01-3870
    a trip with Sharp to collect money as part of their joint
    enterprise in the drug conspiracy. Other testimony con-
    firmed that Sharp was a member of the drug conspiracy
    and that the trip was made to further the ends of the
    drug conspiracy. Therefore, the evidence need not be eval-
    uated in terms of Rule 404(b).
    F.
    At trial, Mr. Westmoreland moved to exclude “evidence
    of drug trafficking conspiracy or of drug quantity.” R.747
    at 3 (citing R.683). The district court concluded that “[t]he
    charges, specifically use of a firearm during and in rela-
    tion to a drug trafficking offense, and murder of a federal
    witness, are directly linked to and intricately related to
    the drug trafficking evidence.” R.747 at 3. The district
    court relied upon our decision in United States v. Chaverra-
    Cardona, 
    879 F.2d 1551
    (7th Cir. 1989). In that case, we
    concluded that “[e]vidence of [the defendant’s] narcotics
    operation, including the amount of drugs involved” and
    “the enormity of [the defendant’s] drug dealings, power,
    and resources” were probative in a trial for a murder
    plot because it provided the jury with useful informa-
    tion with respect to the defendant’s motive and ability to
    carry out the plot. 
    Chaverra-Cardona, 879 F.2d at 1554
    .
    We believe that the district court was on solid ground
    in admitting this evidence. Notably, Mr. Westmoreland’s
    two principal co-conspirators, Abeln and Lewis, testified
    that Mr. Westmoreland was motivated to arrange Debra
    Abeln’s murder in order to protect the drug conspiracy. In
    light of Chaverra-Cardona and the motive linking the con-
    spiracy and the murder, the district court did not abuse
    its discretion in admitting a significant amount of testi-
    mony concerning the drug conspiracy.
    No. 01-3870                                              17
    Conclusion
    The judgment of the district court is affirmed.
