This case arises on appeal following the appellants’ convictions on drug trafficking charges. Because the appellants have failed to establish any errors below justifying reversal, we affirm the appellants’ convictions.
I. STATEMENT OF THE CASE
A. Background Facts
Between January and July 1985, a group of south Florida smugglers, allegedly including appellants Costa, Nunez, and Perry, imported cocaine from the Bahamas into Florida. The smugglers made at least four trips over the course of six months, bringing over 1,800 kilograms of cocaine into the United States.
The group picked up cocaine flown to the Bahamas from Colombia, loaded the cocaine aboard boats in the Bahamas, and sailed to south Florida with their cargo, where the cocaine was unloaded and delivered to distributors. United States Customs agents discovered the June load.
B. Procedural History
On March 3, 1987, a federal grand jury indicted fourteen individuals on various charges including conspiracy to import cocaine, importation of cocaine, conspiracy to possess cocaine with intent to distribute, and possession of cocaine with intent to distribute. On May 12, 1987, the grand jury issued a superseding indictment naming one additional defendant. On August 30, 1987, the grand jury issued a second superseding indictment naming four more individuals. Appellants Costa, Nunez, and Perry were first named in the second superseding indictment. Costa, Nunez, and Perry were all charged in count I with conspiring to import cocaine between November 1984 and July 1985, in violation of 21 U.S.C.A. § 963 (1981), and in count II with conspiracy to possess cocaine with intent to distribute between November 1984 and July 1985, in violation of 21 U.S.C.A. § 846 (1981). Costa and Nunez were charged in counts IV, V, VII, and IX with the importation of cocaine related to drug importations in January and February of 1985, in violation of 21 U.S.C.A. § 952(a) (1981) and 18 U.S.C.A. § 2 (1969). Nunez was also charged in counts III and X with possession of cocaine with intent to distrib *922 ute in violation of 21 U.S.C.A. § 841(a) (1981) and 18 U.S.C.A. § 2. Finally, Perry was charged in counts VIII and XV with possession of cocaine with intent to distribute in violation of 21 U.S.C.A. § 846.
All but six of the nineteen persons indicted pled guilty to the charges. However, appellants Costa, Nunez, and Perry were among those who pled not guilty and proceeded to trial. After a six week trial, a jury found Costa and Nunez guilty on all counts. Perry was found guilty on counts II, VIII, and XV and not guilty on count I.
The district court sentenced all three defendants to terms well within the statutory limits for the relevant crimes. 1 Finally, the lower court, pursuant to 18 U.S.C.A. § 4205(b)(1) (1976), ordered that Costa would not be eligible for parole until he served one-third of his sentence. Defendants Costa, Nunez, and Perry now bring a direct appeal of their criminal convictions before this Court.
II. ISSUES PRESENTED
Appellants raise nine issues on appeal. Three of these issues merit close examination and discussion by this Court. First, Costa, Nunez, and Perry all allege that the district court abused its discretion by limiting the testimony of defense witness Roger Furbee. Second, Costa and Nunez claim that the district court abused its discretion by admitting extrinsic evidence of unindict-ed offenses related to drug smuggling. Finally, Costa and Nunez challenge their conviction on three counts of importing cocaine in the January 1985 importation, claiming that convictions on all three counts constituted impermissible multiplicity. The remaining six issues raised by the appellants do not warrant extended discussion and will be addressed summarily.
III. ANALYSIS
A. Partial Exclusion of Roger Fur-bee’s Proffered Testimony
All three appellants claim that the district court erred when it limited defense witness Roger Furbee’s testimony. Furbee would have testified that, although he imported cocaine in February, March, and June of 1985 with three of the government’s witnesses (Ellsworth, Hanlon, and Roloff), he had never seen or heard of appellants in connection with his smuggling. Furbee’s testimony would have tended to show that the defendants were not, in point of fact, engaged in the smuggling operation. Because the only evidence linking the defendants to the importation phase of the operation was the testimony of government witnesses, the exclusion of significant portions of Furbee’s testimony cannot be lightly dismissed.
The district court, after hearing Furbee’s testimony outside the presence of a jury, held that Furbee could testify about the June 1985 shipment, but prohibited him from testifying about the two other shipments in which he participated and his “standby status” for the January load. We review the district court’s decision to exclude a significant portion of Furbee’s proffered testimony under the abuse of discretion standard of review.
Richardson v. McClung,
The district court reached its decision to bar Furbee’s exculpatory testimony under two separate analyses. The court found, sua sponte, that Furbee’s involvement with Ellsworth related to a different conspiracy than the one alleged at trial. The court based this finding of unrelated conspiracies on Furbee’s inability to recall certain details regarding the boats used to import the cocaine and on differences in Furbee’s recollection of the operations from the descriptions provided by the other conspirators. The district court held that admission of Furbee’s testimony regarding importations other than the June importation would tend to confuse the jury because the testimony related to a second conspiracy, and therefore that its admission would violate Feder
*923
al Rule of Evidence 403.
2
The court also analyzed Furbee’s proffered testimony under Rule 608(b).
3
The district court reasoned that the defense was attempting to impeach the general credibility of Ells-worth, Hanlon, and Roloff with extrinsic evidence of specific instances of misconduct unrelated to the conspiracy at issue. Rule 608(b) “prohibits the use of extrinsic evidence merely to impeach the general credibility of a witness.”
United States v. Calle,
Although we are concerned by the lower court’s Rule 403 ruling, we are not prepared to hold that it constituted an abuse of discretion by the trial court. The abuse of discretion standard imposes a heavy burden on the party seeking to reverse a district court’s evidentiary ruling.
See Balogh’s of Coral Gables, Inc. v. Getz,
Our analysis of whether the lower court abused its discretion begins with the observation that the law of this Circuit strongly favors admitting evidence that may or may not relate to the indicted conspiracy and allowing the jury to decide whether the evidence relates to the conspiracy at issue (and thus is relevant evidence) or whether it relates to a separate and unrelated conspiracy (and, consequently, is irrelevant).
United States v. Gonzalez,
Based on Furbee’s testimony, it was possible, although not certain, that Furbee was acting as part of the same conspiracy in which the defendants allegedly participated. The trial court, in order to exclude portions of Furbee’s testimony under Rule 403 because of a danger of jury confusion, had to find that the evidence established convincingly that Furbee’s proffered testimony related to a conspiracy different
*924
from the indicted conspiracy.
See Gonzalez,
Were this panel conducting a
de novo
review of the district court’s ruling, we would probably admit all of Furbee’s proffered testimony. Based on the record before us, Furbee’s testimony appears to be of the sort that, under
Gonzalez,
is properly left for the jury to consider.
Gonzalez,
This Court’s role, however, is limited to reviewing the district court’s determination for abuse of discretion. In this case, we are not prepared to say that a reasonable district court could not come to a conclusion contrary to our own without abusing its discretion. This Court has emphasized that “the trial judge is accorded the broadest discretion in determining whether evidence should be excluded under Rule 403.”
Borden, Inc. v. Florida East Coast Ry. Co.,
The district court also characterized Furbee’s testimony as extrinsic evidence of specific actions offered for the purpose of impeaching the government witnesses’ character, and held the evidence inadmissible under Rule 608(b). We reject this por
*925
tion of the district court’s analysis. A trial judge’s discretion “does not extend to the exclusion of crucial relevant evidence establishing a valid defense.”
United States v. Wasman,
B. Admission of Extrinsic Evidence of Prior Drug Smuggling
The lower court allowed government witnesses to testify about prior, uncharged drug smuggling activities involving Nunez and Costa. Rule 404 prohibits the admission of extrinsic evidence of misconduct, except as provided in Rule 404(b). The lower court held that the evidence was admissible for the legitimate purpose, under Rule 404(b), of establishing intent, a material element of the conspiracy charge. Nunez and Costa claim that the extrinsic evidence should not have been admitted, because it was prejudicial and they did not specifically challenge the existence of intent. This contention is without merit.
In this Circuit, extrinsic evidence of unindicted bad acts is admissible if the evidence is relevant to an issue other than the defendant’s character and the probative value of the evidence is not substantially outweighed by its potential for causing undue prejudice.
United States v. Hewes,
The appellants claim that they never specifically “put intent at issue,” and therefore that the government could not rely on intent as a basis for the admission of the evidence. However, “[t]he law in this Circuit provides that intent becomes a material issue whenever a defendant pleads not guilty to a charge of conspiracy unless the defendant affirmatively withdraws the element of intent from the case.”
United States v. Hernandez,
*926
The second step for reviewing extrinsic evidence relates to whether the probative value of the evidence is outweighed by its prejudicial effect. The law in this Circuit requires that the Rule 404(b) evidence actually be necessary to establish the material element.
Hewes,
The government’s case is not particularly strong on the issue of intent. Indeed, appellants in another argument suggest that the lower court’s refusal to allow Furbee’s testimony was sufficiently prejudicial to warrant a new trial because the government’s only evidence of the appellants’ participation in the conspiracy was testimonial. The appellants cannot now gainsay that the admission of the extrinsic evidence was unnecessary because the government’s case was sufficiently strong without it. Therefore, we hold that the district court did not abuse its discretion in admitting the extrinsic evidence of unindicted bad acts.
C. The Three Importation Charges
Costa and Nunez challenge their conviction on three counts of importing cocaine in the January 1985 importation. They argue that because the load started in one lump in the Bahamas and ultimately wound up as one lump in Florida, the fact that it actually came into the United States on three boats is irrelevant. Costa and Nunez claim that the three convictions for importing cocaine constitute multiplicitous convictions for the same offense. This argument lacks merit.
Although this court has condemned multiplicity when it exists, it does not exist on these facts. The government alleged conspiracy and three counts of importation. In order to avoid multiplicity, only one fact or element need be different between each charge.
Blockburger v. United States,
Appellants claim that
United States v. Fiallo-Jacome,
D. The Appellants’ Remaining Six Claims
Costa, Nunez, and Perry raise six additional arguments, none of which merits extended discussion. However, because the appellants have seen fit to raise them, this Court will address each specific claim.
All three appellants object to the district court’s restrictions on the cross examination of government witness Ells-worth. The district court prohibited the appellants from quizzing Ellsworth on his views on the criminal justice system in general and the justice of his conviction in particular. The court allowed cross-examination for information regarding Ells-worth’s plea agreement, for information about his involvement in the conspiracy, and for bias. Thus, the district court provided the defendants with the opportunity to cross-examine Ellsworth on any material issue. On these facts, there is no colorable claim that the court denied defendants their Sixth Amendment right to cross examine adverse witnesses.
United States v. Beale,
Costa objects to the district court’s order that he not be eligible for parole until he serves at least one third of his sentence (20 years). The district court made this order pursuant to 18 U.S.C.A. § 4205(b)(1), which provides that a court may “designate in the sentence of imprisonment imposed a minimum term at the expiration of which the prisoner shall become eligible for parole, which term may be less than but shall not be more than one-third of the maximum sentence imposed by the court.” This court in
United States v. Berry,
Nunez appeals the lower court’s failure to find a violation of the court’s Federal Rule of Evidence 615 sequestration order based on an out-of-court conversation between two government witnesses (Roberto and Ellsworth). The district court heard testimony on the alleged breach of its sequestration order, but concluded that the evidence did not support a finding that government witnesses Roberto and Ells-worth breached the order. Having made a factual finding that the order was not breached, the district court declined to call a mistrial, strike the witnesses’ testimony, or instruct the jury that the witnesses violated the order. The court did, however, allow Perry to cross-examine the witnesses about any conversations that they may have had during the pendency of the trial. The court did not allow Nunez to assert to the jury that the witnesses had violated the order, but did allow Nunez’s counsel to tell the jury that the two witnesses had talked with each other about matters related to the pending case. 10 Because Nunez presents no evidence suggesting that the *928 district court was clearly erroneous in finding that the witnesses did not breach the court’s order, this Court will defer to the lower court’s handling of this problem.
Appellant Perry argues that because the testimony regarding her involvement given by two government witnesses was not entirely consistent, she should have been acquitted pursuant to Federal Rule of Criminal Procedure 29. 11 The witnesses’ testimony was far from irreconcilable and to the extent there were differences they did not establish Perry’s innocence. The court correctly rejected Perry’s Rule 29 motion.
Perry and Nunez challenge the length of their sentences as being disproportionate to those given to other indictees in the conspiracy who pled guilty. However, “[a] sentencing judge has broad discretion in the imposition of criminal sentences.”
United States v. Restrepo,
Finally, Perry asks for a reversal and a remand because the court admitted a “brown box” containing cocaine into evidence at trial. The cocaine found on the boat was in yellow and blue bags. Counsel for the United States explains that the brown box contained nine packages of cocaine and was merely used to carry the cocaine into the courtroom. The parties stipulated that the government discovered 163 packages of cocaine weighing 360 pounds on the seized boat. Moreover, Perry made no objection to the admission of the brown box at trial. This point is utterly without merit.
IV. CONCLUSION
For the foregoing reasons, the criminal convictions of appellants Costa, Nunez, and Perry are AFFIRMED.
Notes
. Sentencing in this case predated the federal sentencing guidelines.
. Rule 403 requires the exclusion of relevant evidence if its probative value is "substantially outweighed” by the evidence’s tendency to cause undue prejudice. Fed.R.Evid. 403.
. Rule 608(b) prohibits the impeachment of a witness through extrinsic evidence, other than convictions, of specific instances of misconduct. Fed.R.Evid. 608(b).
. Rule 104(b) provides that:
Relevancy conditioned on fact. When the relevancy of evidence depends upon the fulfillment of a condition of fact, the court shall admit it upon, or subject to, the introduction of evidence sufficient to support a finding of the fulfillment of the condition.
.In the case sub judice, Furbee’s proffered testimony would have tended to exculpate appellants. If Furbee was an active participant with several of the principals in the conspiracy and imported cocaine into the United States with them on several occasions, then evidence that Furbee did not know the defendants would tend to establish their lack of participation in the importation phase of the conspiracy and thus their innocence.
. This approach is entirely consistent with the law of this Circuit holding that "[a] single conspiracy does not become many simple because of the changing composition of the personnel comprising the conspiracy or because some members performed only a single function.”
United States v. Meester,
. This is not to say that in a particular case a district court is precluded from finding that the relevance of specific evidence that may relate to the indicted conspiracy is "substantially outweighed” by its potential for prejudice. Fed. R.Evid. 403. Rule 403 can and should be used to bar the admission of evidence when its admission would interfere with the jury’s ability to decide a case fairly.
.The district court doubted Furbee’s veracity, and believed that his recollections of the details of the conspiracy were sufficiently poor so as to raise substantial doubts as to whether his testimony related in any way to the indicted offense. These findings justified the exclusion of the evidence under Rule 403. Moreover, such findings are essentially factual determinations, which this Court will not reconsider unless clearly erroneous. The appellants have presented this Court no additional evidence suggesting that Furbee’s familiarity with the details of the conspiracy was more substantial than the district court found it to be. Consequently, this Court has no basis from which to infer that the lower court’s factual findings regarding the depth of Furbee’s knowledge of the conspiracy were clearly erroneous.
. Were this argument to hold true, then even if the cocaine were smuggled into the United States at different locations via various means of transportation, there should be only one violation of § 952 provided that the smugglers are careful about ultimately reaggregating their goods.
. Nunez’s argument lacks merit given the court’s finding that the order was not violated. Cross-examination is one of the three remedies provided for violations of sequestration orders, although it must usually be accompanied by a court statement to the jury that the sequestration order was violated.
United States v. Lattimore,
. Rule 29. Motion for Judgment of Acquittal
(a) Motion Before Submission to Jury.
Motions for directed verdict are abolished and motions for judgment of acquittal shall be used in their place. The court on motion of a defendant or of [sic] its own motion shall order the entry of judgment of acquittal of one or more offenses charged in the indictment or information after the evidence on either side is closed if the evidence is insufficient to sustain a conviction of such offense or offenses. If a defendant's motion for judgment of acquittal at the close of the evidence offered by the government is not granted, the defendant may offer evidence without having reserved the right.
