OPINION

PER CURIAM:

Domingo Nolberto Pena, Ronthany Leo Ward, Lamont Harold
Garrison, and Lawrence Bernard Garrison appeal their convictions
and sentences for conspiracy to distribute cocaine and crack cocaine.
See 21 U.S.C.A. § 846 (West 1999). Pena also appeals an additional
conviction for possession with intent to distribute crack cocaine. See
21 U.S.C.A. § 841(a)(1) (West 1999). We affirm.

I.

The facts, viewed in the light most favorable to the Government as
we must following conviction, see Glasser v. United States, 315 U.S.
60, 80 (1942), are as follows. Appellants, along with eleven others,
were named in a multi-count indictment arising out of their associa-
tion with an extensive cocaine and cocaine base ("crack") distribution
organization operating in Virginia, Maryland, and Washington, D.C.
In early 1995, Samuel Suero and Felix Ogando were distributing
cocaine in the New York City area, which they were obtaining from
other Dominican traffickers in the city, including Humberto Fransisco
Sanchez-Peralta and Richard Orozco-Oviedo.1 In order to locate addi-
tional cocaine and crack customers, Suero contacted his cousin and
former drug distribution associate, Edwin Rodriguez, who had
resumed his drug distribution activities shortly after his release from
federal prison in 1993. This prompted a meeting between Suero,
Ogando, Edwin Rodriquez, and Edwin's brother, Bernardo
Rodriquez, in Washington D.C. to discuss expanding their trafficking
activities into Washington D.C. and Virginia.2 After the meeting,
_________________________________________________________________
1 Sanchez-Peralta and Orozco-Oviedo were indicted along with appel-
lants in this case. At the time of the trial, Orozco-Oviedo had pled guilty
to conspiracy to distribute cocaine and Sanchez-Peralta was a fugitive.
2 Samuel Suero, Bernardo Rodriguez, Edwin Rodriguez, and Lamont
Crumity had all been indicted in 1990 on drug conspiracy charges.
Edwin Rodriguez and Lamont Crumity were both convicted. Edwin
Rodriquez was released from prison in 1993, and Crumity was released
in early 1995. Suero had fled to his home in the Dominican Republic to
escape arrest, but returned to the United States in 1991 to resume his
drug distribution activities. Bernardo Rodriguez was not arrested until
August 1996.

                    3
Edwin Rodriguez began to distribute cocaine and crack for Suero and
Ogando. This included supplying the drugs to Lamont Crumity and
Tito Abea. The cocaine was packaged in balls surrounded with black
tape. Normally, Ogando transported the drugs from New York to the
other areas.

Crumity, in turn, supplied crack to Ronthany "Ronnie" Ward, who
had been his prior customer, as well as to Ronnie Green and Raynell
DeCamp. In the late summer of 1995, Rodriquez and Suero were
stopped by the New Jersey State Police and found to be carrying a
large sum of money. Rodriguez was incarcerated for violating his
parole, prompting Suero and Ogando to begin directly distributing to
Crumity and Abea. Likewise, when Crumity was arrested in Novem-
ber 1996, Suero and Ogando began to distribute directly to Ward. In
early February 1997, Ward sold crack cocaine to an informant and,
several days later, to the informant and an undercover officer. The
second deal was videotaped.

In the summer of 1996, Suero and Ogando also began to supply
Domingo Pena with crack cocaine. Pena had been previously supplied
by Johnny Clarke, who had been supplied by Suero and Ogando until
they cut him off for unpaid debts. The crack cocaine delivered to Pena
was also packaged in balls surrounded by black tape. And cocaine
purchased in a controlled buy from Pena by the Arlington County
Police in August 1996 was similarly packaged in black tape.

Like Crumity, Tito Abea also had customers to whom he distrib-
uted. They included co-defendants Frederick Bush, Jackie Moore, and
Jose Contreras. In August 1996, Tito Abea and his brother Pedro
Abea opened P & T Auto Body Shop in Maryland and Tito Abea
began to distribute cocaine from the shop to twin brothers Lamont
and Lawrence Garrison. On one occasion in January 1997, Ogando
directly distributed cocaine to Lamont and Lawrence Garrison at Tito
Abea's request. In addition to the testimony of Tito Abea and Felix
Ogando concerning these drug transactions, Pedro Abea testified that
he observed Tito Abea engaging in drug deals with the Garrisons at
the shop, and that he also saw Ogando deliver black balls of cocaine
to the Garrisons at the shop. In January 1997, Ogando was arrested
in possession of four packages of cocaine wrapped in black tape. Tito
Abea testified that the Garrisons paged him on the evening of Ogan-

                    4
do's arrest. When he returned the call, Abea testified that Lamont
Garrison said that he and Lawrence had seen the police stop Ogando
and Pedro Abea in Abea's automobile, and that the black balls of
cocaine had been placed on the top of the automobile. Law enforce-
ment officers confirmed that black balls had been placed on the hood
of the Abea automobile and that Lamont Garrison's automobile was
seen driving by the scene during the arrest.

Following a jury trial, appellants were each convicted of conspir-
acy to distribute cocaine and crack cocaine. See 21 U.S.C.A. § 846.
Pena was also convicted of an additional charge of possession with
intent to distribute crack cocaine. See 21 U.S.C.A. § 841(a)(1). Pena
was sentenced to 292 months imprisonment. Ward was sentenced to
248 months imprisonment. Lamont Garrison was sentenced to 235
months imprisonment, and Lawrence Garrison was sentenced to 188
months imprisonment. All appellants were additionally sentenced to
a five-year term of supervised release, plus a special assessment. They
appeal their convictions and sentences on numerous grounds.

II.

We first address appellants' various challenges to their convictions.
For the reasons enunciated below, we find no reversible error and
affirm.

A.

Appellants' first challenge is to the district court's refusal to give
a requested jury instruction on the credibility of cooperating govern-
ment witnesses. We review the district court's failure to give the
requested instruction for an abuse of discretion. See United States v.
Ruhe, 191 F.3d 376, 384 (4th Cir. 1999). A refusal to grant a
requested instruction is reversible error only if the instruction
"(1) was correct; (2) was not substantially covered by the court's
charge to the jury; and (3) dealt with some point in the trial so impor-
tant, that failure to give the requested instruction seriously impaired
the defendant's ability to conduct his defense." United States v. Lewis,
53 F.3d 29, 32 (4th Cir. 1995) (internal quotation marks omitted).

                    5
Appellants' proposed instruction sought to remind the jury that the
co-conspirator witnesses had entered into plea agreements with the
government, and that under the agreements they were cooperating in
the government's investigation in the hope that the government would
persuade the district court to either impose a more lenient sentence
upon them or reduce a sentence that had already been imposed upon
them. The requested instruction went on to state that the testimony
"must be examined and weighed by the jury with greater care than the
testimony of a witness who has not testified pursuant to a cooperation
agreement." J.A. 553.

In the instructions actually given by the district court, the jury was
advised that they were the sole judges of credibility, that they were
to scrutinize carefully "the circumstances under which each witness
has testified," and that they should "consider any relation each witness
may bear to either side of the case." J.A. 1281. The jury was also spe-
cifically reminded that some of the government's witnesses had
reached plea agreements with the government and that the jury
"should consider whether the witnesses who fit that circumstance are
testifying falsely and in order to obtain favorable consideration from
the government or some other disposition in their own case." J.A.
1286; cf. United States v. Herrera, 832 F.2d 833, 836 (4th Cir. 1987)
(noting with approval the district court's "caution[] [to] the jury that
plea agreements often give government witnesses a motive to testify
falsely and that the jury should weigh such testimony carefully.").

We conclude that the district court did not abuse its discretion in
rejecting the appellants' proposed instruction on the credibility of
cooperating witnesses. The substance of the proposed instruction was
"substantially covered by the court's charge to the jury" and the dis-
trict court's mere failure to word it in the manner suggested by appel-
lants in no way impaired their ability to conduct their defense. Lewis,
53 F.3d at 32.

B.

All appellants next challenge the district court's decision to admit
into evidence a photographic chart depicting twenty-two purported
participants in the conspiracy, including the appellants and their
eleven co-defendants. A district court's decision to allow the use of

                    6
"summary charts `will not be overturned on appeal unless [the] deci-
sion is shown to be arbitrary or irrational.'" United States v. Loayza,
107 F.3d 257, 264 (4th Cir. 1997) (quoting United States v. Johnson,
54 F.3d 1150, 1156 (4th Cir. 1995)).

It is well-established that a district court may admit summary testi-
mony and summary charts, under Rule 611(a) of the Federal Rules of
Evidence, if they will help the jury to better understand the evidence
presented and to ascertain the truth. See Johnson, 54 F.3d at 1159. In
making this determination, "the length of the trial, the complexity of
the case, and the accompanying confusion that a large number of wit-
nesses and exhibits may generate for the jury" is considered. Id. at
1159; see Loayza, 107 F.3d at 264. The possible prejudice to the
defendant by allowing the summary chart into evidence must also be
considered. See Johnson, 54 F.3d at 1159. However, any such "preju-
dice may be dispelled by giving the defendant an opportunity to
cross-examine the individual who prepared the chart. In addition, a
cautionary jury instruction may be requested and given." Loayza, 107
F.3d at 264 (internal citation omitted).

The photographic chart objected to by the appellants was intro-
duced by the government during its direct examination of an investi-
gating FBI officer. The chart consisted of no information beyond the
photographs of the twenty-two alleged participants in the drug organi-
zation, including appellants, with their names printed underneath.
These persons were referred to frequently throughout the trial and the
accuracy of the photographs, to which witnesses had testified, was not
questioned. Rather, appellants took issue with the manner in which
the photographs were arranged on the chart. Specifically, while the
chart contained no explicit ranking information, the photographs were
grouped according to the allegations in the indictment and the testi-
mony presented at trial. For example, Orozco-Oviedo and Sanchez-
Peralta were at the top of the exhibit, followed underneath by Suero
and Ogando, followed underneath by Lamont Crumity, Domingo
Pena, Edwin Rodriguez, and Tito Abea. These men, in turn, were
each grouped with the persons to whom they supplied cocaine and
crack cocaine.

The district court overruled appellants' objection to the admission
of the chart, noting that the jury would likely have difficulty keeping

                    7
up with the large number of witnesses, parties, and other co-
conspirators and, therefore, that the chart would aid the jury in the
decisional process. See Johnson, 54 F.3d at 1160 ("In light of the
complex nature of the extended drug conspiracy and the large number
of witnesses presented, we conclude that the summary chart likely
helped the jury in sifting through the testimony in the case."). The
arrangement itself was consistent with the trial testimony, including
that of Orozco-Oviedo, Suero, Ogando, Edwin Rodriguez, Abea,
Crumity, and seven additional co-conspirators. And these witnesses,
along with the FBI and Task Force case agents, were all available for
cross-examination by defense counsel.

Appellants nevertheless assert that admission of the chart was prej-
udicial and that, despite the opportunities for cross-examination, the
district court abused its discretion in admitting the chart into evidence
without giving a specific limiting instruction. They admit that they
requested no such instruction once the district court ruled that the
chart was admissible, but assert that it was the judge's duty, and not
their own, to ensure that the jury was so instructed. We disagree. The
propriety of cautionary instructions is one safeguard that may be
employed to minimize the prejudicial effect of a summary chart, see
Loayza, 107 F.3d at 264; Johnson, 54 F.3d at 1160-61, but we have
never held it to be the sole or determining factor. We decline to do
so today, particularly in a case, such as this, where the summary chart
and the testimony introducing it presented very little in the way of
information and defense counsel may well have made the strategic
decision not to request a limiting instruction. See Loayza, 107 F.3d at
264 ("[A] cautionary jury instruction may be requested and given.")
(emphasis added). Accordingly, we find no abuse of discretion in the
district court's decision to allow the photographic chart into evidence.

C.

Appellants Pena, Ward, and Lawrence Garrison contend that the
district court should have granted their motion for a mistrial because
the prosecutor indirectly commented on their failure to testify. To
determine whether the prosecution has, through an indirect remark,
improperly commented on an accused's failure to testify in violation
of the Fifth Amendment, we apply the following test:"Was the lan-
guage used manifestly intended to be, or was it of such character that

                     8
the jury would naturally and necessarily take it to be a comment on
the failure of the accused to testify?" United States v. Anderson, 481
F.2d 685, 701 (4th Cir. 1973) (internal quotation marks omitted),
aff'd, 417 U.S. 211 (1974).

In reply to attacks upon the credibility of the co-conspirators who
testified for the government during the closing arguments of defense
counsel, the prosecutor responded that these attacks were motivated
by the knowledge that if the jury believed the co-conspirators, "the
defendants are guilty as charged . . . [b]ecause there's no evidence to
the contrary." J.A. 1251. The district court denied the appellants'
ensuing motion for a mistrial, but gave a curative instruction.

Because we have previously rejected similar challenges to a prose-
cutor's reference to the "uncontradicted" nature of certain evidence or
testimony, we affirm the district court's denial of the appellants'
motion for a mistrial. See United States v. Francis, 82 F.3d 77, 78
(4th Cir. 1996) (government's statement during closing that "[t]he
evidence is uncontradicted" was not an improper comment on the
accused's failure to testify); United States v. Percy, 765 F.2d 1199,
1204-05 (4th Cir. 1985) (statement that testimony was "unrefuted and
unrebutted" was not an improper comment on the accused's failure to
testify); United States v. Jenkins, 544 F.2d 180, 180-81 (4th Cir.
1976) (read in context, a statement that testimony was "uncontra-
dicted" was not "`manifestly intended to be,[nor] was it of such char-
acter that the jury would naturally and necessarily take it to be a
comment on the failure of the accused to testify.'") (quoting Ander-
son, 481 F.2d at 701). We see little difference between a prosecutor's
statement that evidence is "uncontradicted" or"unrefuted and unre-
butted" and a prosecutor's statement that there was "no evidence to
the contrary." Indeed, appellants acknowledge our prior precedents,
but assert, in reliance upon our opinion in Jenkins, that such com-
ments do rise to the level of an improper comment on the failure of
an accused to testify if the defendant is the only person who could
have refuted or rebutted the prosecution's evidence. We, however,
rejected a nearly identical argument in Francis :

          While in Jenkins we did suggest that a prosecutorial refer-
          ence to "uncontradicted" evidence in circumstances where
          the only person who could possibly contradict the testimony

                    9
          was the nontestifying defendant "might well" implicate the
          right against self-incrimination, this suggestion was only
          dictum. And, at that, the dictum was foreclosed by our hold-
          ing in the case.

Francis, 82 F.3d at 79 (internal citation omitted). Examining the
statement in the context in which it was made, as we must, we are sat-
isfied that the prosecutor's statement that there was "no evidence to
the contrary," J.A. 1251, was not "manifestly intended to be, or . . .
of such character that the jury would naturally and necessarily take it
to be a comment on the failure of the accused to testify." Anderson,
481 F.2d at 701. Therefore, the district court did not err in denying
appellants' motion for a mistrial.

D.

Next, Ward appeals the district court's decision to allow Lamont
Crumity to testify about Ward's participation in the distribution of
crack cocaine prior to the charged date of the conspiracy and to allow
a law enforcement officer to testify about various incriminating items
seized from Ward's apartment during the execution of a search war-
rant in July 1997. Although seemingly acknowledging that the evi-
dence had at least some probative value, Ward asserts that it was not
admissible under Rule 404(b) of the Federal Rules of Evidence and,
further, that any probative value was outweighed by its prejudicial
effect and should have been excluded under Rule 403 of the Federal
Rules of Evidence. We review the district court's decision to admit
the evidence under the narrow abuse of discretion standard. See
United States v. Grimmond, 137 F.3d 823, 831 (4th Cir.), cert. denied,
525 U.S. 850 (1998); United States v. Queen, 132 F.3d 991, 993 (4th
Cir. 1997), cert. denied, 523 U.S. 1101 (1998). Such decisions will
not be reversed unless they are "arbitrary or irrational." United States
v. Powers, 59 F.3d 1460, 1464 (4th Cir. 1995) (internal quotation
marks omitted).

Ward's first challenge pertains to the testimony of Lamont
Crumity. Crumity testified that he engaged in repeated drug transac-
tions with Ward from approximately July 1995 until Crumity's arrest
in November 1996, a period which was encompassed within the time
frame of the indictment. Additionally, Crumity testified that he and

                    10
Ward had engaged in drug transactions on a regular basis from 1987
to October 1990, and that Ward was also distributing crack cocaine
during this time period. Ward appeals the district court's decision to
allow Crumity to testify regarding transactions which preceded the
time frame of the indictment, primarily because Crumity had been
previously convicted and was a co-conspirator with a motive to lie
about Ward's involvement.

Ward's second challenge is to the district court's decision to allow
an investigating law enforcement officer to testify that, during a
search of Ward's apartment in July 1997, officers found weapons,
including a loaded 9 mm firearm by the front door, ammunition,
shoulder holsters for weapons, cash, a scale, plastic zip-lock bags
containing heroin, and marijuana. Ward asserts that this evidence was
particularly prejudicial because it was preceded by the testimony of
an undercover officer who testified that two controlled purchases of
crack cocaine were made from Ward in February 1997.

We find no error in the district court's admission of this evidence.
First, "evidence of uncharged conduct is not considered `other crimes'
evidence if it arose out of the same . . . series of transactions as the
charged offense, . . . or if it is necessary to complete the story of the
crime (on) trial." United States v. Kennedy , 32 F.3d 876, 885 (4th Cir.
1994) (internal quotation marks omitted). And "[i]t is well-established
. . . that the mere fact that the evidence involved activities occurring
before the charged time frame of the conspiracy does not automati-
cally transform that evidence into `other crimes' evidence." Id.

In this circumstance, the previous drug distribution activities
between Crumity and Ward provided the context for the charged con-
spiracy by revealing important background information about Ward
and explaining how Ward and Crumity came to be engaged in distri-
bution activities during the time frame of the indictment. The items
recovered during the search of Ward's residence, although recovered
after the last alleged overt act specified in the indictment, were recov-
ered within the time frame of the charged conspiracy. And the items
located -- guns, ammunition, shoulder holsters, cash, scales, and
drugs -- were all well-recognized tools of the drug distribution trade,
see generally United States v. Gastiaburo, 16 F.3d 582, 588 (4th Cir.
1994) (upholding admission of expert testimony that beepers and

                     11
address books are commonly used by drug traffickers); United States
v. Barth, 990 F.2d 422, 425 (8th Cir. 1993) (noting that pagers are
tools of the drug trade); United States v. Ricks , 882 F.2d 885, 892 (4th
Cir. 1989) (upholding admission of evidence of firearms at drug con-
spiracy trial under Rule 404(b)), and "inextricably intertwined" with
Ward's participation in the ongoing drug distribution business. United
States v. Chin, 83 F.3d 83, 88 (4th Cir. 1996) (internal quotation
marks omitted).

Second, even were the evidence only admissible under Rule
404(b), such other crimes, wrongs, or acts are "generally admissible
except when . . . offered to prove `the character of a person in order
to show action in conformity therewith.'" Queen, 132 F.3d at 994
(quoting Fed. R. Evid. 404(b)). "[W]ith only the one stated exception,
[Rule 404(b)] is understood to be a rule of inclusion, authorizing evi-
dence of prior acts for purposes other than character, such as `motive,
opportunity, intent, preparation, plan, knowledge, identity, or absence
of mistake or accident.'" Id. (internal citations omitted). By pleading
not guilty, Ward denied that he was a participant in the drug distribu-
tion conspiracy. Thus, Ward's involvement in drug transactions prior
to the dates of the charged conspiracy, and the presence of guns,
scales, and other tools of the drug trade in his apartment during the
time frame of the charged conspiracy, were facts relevant to the issues
of Ward's knowledge and intent, providing an indication that he was
both aware of and participating in the conspiracy and intent upon pro-
tecting its operations. See United States v. Sanchez, 118 F.3d 192,
195-96 (4th Cir. 1997) (evidence that defendant had conducted drug
deals outside the time frame charged in the conspiracy and that he
was arrested near an automobile which contained drugs and in which
he had just been a passenger was properly admitted under Rules
404(b) and 403); United States v. McMillon, 14 F.3d 948, 955 (4th
Cir. 1994) (evidence which "explain[ed] to the jury how the illegal
relationship between participants in the crime developed" was admis-
sible under Rules 404(b) and 403) (internal quotation marks omitted).

Having concluded that the evidence was admissible, we must still
address Ward's contention that its probative value was "substantially
outweighed by the danger of unfair prejudice" and, therefore, that it
should have been excluded under Federal Rule of Evidence 403. For
the reasons previously indicated, the challenged evidence was

                    12
strongly probative of Ward's participation in the criminal conspiracy
for which he was charged. It was, of course, also prejudicial, as is all
such inculpatory evidence. See Sanchez, 118 F.3d at 196. But having
reviewed the record, we cannot say that the district court abused its
discretion in determining that the probative value of the evidence was
not substantially outweighed by its prejudicial effect.

E.

Lamont Garrison and Lawrence Garrison appeal the district court's
denial of their motion to sever their trial from that of their co-
defendants. They, joined by Ward, first contend that their cases were
misjoined under Rule 8(b) of the Federal Rules of Criminal Proce-
dure. In the alternative, the Garrisons contend that the joint trial was
unduly prejudicial and should have been severed from that of Ward
and Pena under Rule 14 of the Federal Rules of Criminal Procedure.
The district court's decision to deny a motion for severance will not
be overturned absent an abuse of discretion. See United States v.
Reavis, 48 F.3d 763, 767 (4th Cir. 1995).

1.

Under Rule 8(b) of the Federal Rules of Criminal Procedure,
"[t]wo or more defendants may be charged in the same indictment or
information if they are alleged to have participated in the same act or
transaction or in the same series of acts or transactions constituting an
offense or offenses." In such cases, the "defendants may be charged
in one or more counts together or separately and all of the defendants
need not be charged in each count." Fed. R. Crim. P. 8(b).

We disagree with the appellants' assertion that the government
failed to present a sufficient link between the Garrisons, Ward, and
Pena for the purposes of joinder under this Rule. Lamont Garrison,
Lawrence Garrison, Ward, and Pena, together with eleven additional
co-conspirators, were indicted for their participation in a criminal
conspiracy spanning more than a three-year period. The evidence
overwhelmingly confirmed that all defendants named in the indict-
ment participated at some level in the single conspiracy. Samuel
Suero and Felix Ogando, who were located in New York, obtained
cocaine from Dominican suppliers. These drugs were, in turn, either

                     13
sold or fronted to the other members of the conspiracy. With regard
to appellants, the evidence revealed that Suero and Ogando furnished
drugs to Pena; to Tito Abea, who in turn supplied the Garrisons; to
the Garrisons directly on one occasion; to Lamont Crumity, who in
turn supplied Ward; and to Ward directly after Crumity was arrested.
The commonality of the drug distribution organization was also
revealed by testimony that the drugs being distributed were consis-
tently packaged in balls surrounded by black tape. Thus, we are satis-
fied that Lamont Garrison, Lawrence Garrison, Ward, and Pena were
appropriately indicted together under Rule 8(b) of the Federal Rules
of Criminal Procedure.

2.

The Garrisons next assert that, even if they were properly indicted
with the other co-conspirators, the district court erred in denying their
motion to sever under Rule 14 of the Federal Rules of Criminal Pro-
cedure due to the prejudicial effect of evidence admitted against the
others. We disagree.

Under Rule 14, the district court may grant a severance if "[i]t
appears that a defendant or the government is prejudiced by a joinder
of offenses or of defendants in an indictment or information or by
such joinder for trial together." Fed. Rule Crim. P. 14. In asserting
that the district court should have allowed them a separate trial, the
Garrisons urge us to depart from the standard rule"that defendants
who are charged in the same criminal conspiracy should be tried
together." Reavis, 48 F.3d at 767; see Zafiro v. United States, 506
U.S. 534, 537 (1993); United States v. Brugman , 655 F.2d 540, 542
(4th Cir. 1981). Essentially, they contend that this is because they
were substantially prejudiced by the spillover evidence of wrongdoing
on the part of Ward and Pena. In particular, they point to the guns and
other drug paraphernalia that was seized during the search of Ward's
apartment, the videotaped drug transaction between Ward and an
undercover officer, and the evidence supporting the conviction
against Pena for possession with the intent to distribute crack cocaine
in the summer of 1996.

We have previously recognized that "[t]he fact that the evidence
against one defendant is stronger than the evidence against other

                     14
defendants does not in itself justify severance[since], [i]f this were
the case, motions to sever [in a conspiracy case] . . . would have to
be granted almost as a matter of course." United States v. Brooks, 957
F.2d 1138, 1145 (4th Cir. 1992). Rather, the Garrisons "must establish
that prejudice would result from a joint trial . . ., not merely that sepa-
rate trials would result in a better chance of acquittal." Id. In the
instant case, there was more than sufficient evidence to support the
Garrisons' convictions and we do not perceive any prejudice to them
merely because the quantity of evidence against Ward and Pena may
have been greater than that against the Garrisons. Nor do we see any
other source of prejudice requiring separate trials. Also, we note that
the district court gave a limiting instruction to the jury at the time the
physical evidence was introduced, emphasizing that the evidence only
pertained to Ward and that, although Pena was convicted of a substan-
tive count in addition to the conspiracy charge, the substantive charge
occurred within the time frame and context of the charged conspiracy.
Accordingly, we conclude that the district correctly denied the Garri-
sons' motion for a severance under Rule 14.

Lamont and Lawrence Garrison also challenge the sufficiency of
the evidence to support their conspiracy convictions. "If there is sub-
stantial evidence to support the [jury's] verdict, after viewing all of
the evidence and the inferences therefrom in the light most favorable
to the Government," the court must affirm. United States v. Murphy,
35 F.3d 143, 148 (4th Cir. 1994). "[S]ubstantial evidence is evidence
that a reasonable finder of fact could accept as adequate and sufficient
to support a conclusion of a defendant's guilt beyond a reasonable
doubt." United States v. Burgos, 94 F.3d 849, 862 (4th Cir. 1996) (en
banc).

The crux of the Garrisons' challenge is that the only evidence con-
necting them to the conspiracy was the testimony of Tito Abea, Pedro
Abea, and Felix Ogando -- all of whom were, according to the Garri-
sons, unreliable witnesses because they testified subject to plea agree-
ments with the government and had a substantial incentive to testify
falsely. However, it is well-established that, when reviewing suffi-
ciency of the evidence claims, "we must remain cognizant of the fact
that `[t]he jury, not the reviewing court, weighs the credibility of the

                     15
evidence and resolves any conflicts in the evidence presented, and if
the evidence supports different, reasonable interpretations, the jury
decides which interpretation to believe.'" Id. at 862 (quoting Murphy,
35 F.3d at 148).

Furthermore, while "[t]he settled law of this circuit recognizes that
the testimony of a defendant's accomplices, standing alone and uncor-
roborated, can provide an adequate basis for conviction," United
States v. Burns, 990 F.2d 1426, 1439 (4th Cir. 1993), such testimony
does not stand alone in this case. Rather, it was corroborated at trial
by Tito Abea's cellular telephone records, which revealed frequent
calls between Abea's cellular telephone and the Garrison residence
and pager. Accordingly, we conclude that the government presented
sufficient evidence to support the convictions obtained against both
Lamont and Lawrence Garrison.

III.

Lamont and Lawrence Garrison also raise several challenges to the
sentences imposed upon them by the district court. First, they jointly
challenge the amount of drugs attributed to each for purposes of sen-
tencing. Second, Lamont Garrison individually challenges the district
court's imposition of a two-level enhancement for obstruction of jus-
tice.

A.

We first address the Garrisons' joint challenge to the amount of
drugs attributed to them for purposes of sentencing. The basis for the
challenge is their assertion that the trial testimony improperly lumped
them together because they are twins and that the district court erred
in crediting the testimony of Tito Abea, whom they believe to be an
unreliable witness. As a result of these alleged improprieties, the Gar-
risons assert that the district court failed to make particularized find-
ings to support the drug amounts assigned to them.

When a defendant disputes the amount of drugs for which he is to
be held responsible, "the district court must make an independent res-
olution of the factual issue at sentencing," and the burden is on the

                     16
government to prove the quantity of drugs by a preponderance of the
evidence. United States v. Gilliam, 987 F.2d 1009, 1013 (4th Cir.
1993). "[T]he credibility of a testifying co-conspirator is for the sen-
tencing judge to assess." United States v. Fisher, 58 F.3d 96, 100 (4th
Cir. 1995); see United States v. Sampson, 140 F.3d 585, 591 (4th Cir.
1998) ("In reviewing sentences imposed under the[United States Sen-
tencing] Guidelines, we must give due regard to the opportunity of the
district court to judge the credibility of the witnesses.") (internal quo-
tation marks omitted). The district court's factual determinations as to
the quantity of drugs properly attributed to a defendant will not be
overturned unless clearly erroneous. See Sampson , 140 F.3d at 591.

We conclude that the district court had sufficient evidence upon
which to justify the drug quantities attributed to both Lawrence and
Lamont Garrison. At sentencing, the district court credited the testi-
mony of Tito Abea, as obviously the jury did during the guilt phase,
and adopted the amounts thereby attributed to the Garrisons under
their respective presentence reports. Further, according to Abea's tes-
timony, the Garrisons received the drugs together, an observation cor-
roborated by the testimony of Pedro Abea and Felix Ogando.
Accordingly, we find no error in the district court's decision to credit
Tito Abea's testimony and to equally attribute the drug activity to
Lamont and Lawrence Garrison. The fact that the brothers consis-
tently acted as partners is supported by the evidence presented and
does nothing to undermine the determination that the amounts attri-
buted to both, while equivalent, were nevertheless properly based
upon each brother's individualized conduct.

B.

We next turn to Lamont Garrison's additional contention that the
district court erred in enhancing his sentence pursuant to U.S. Sen-
tencing Guidelines Manual § 3C1.1 (1997), for obstructing justice by
committing perjury. The district court's determination that Lamont
Garrison committed perjury is also a factual determination reviewable
for clear error. See United States v. Murray, 65 F.3d 1161, 1165 (4th
Cir. 1995).

At trial, Lamont Garrison denied that he had ever received or dis-
tributed drugs, and asserted that his frequent presence at the P & T

                     17
Auto Body Shop was the result of either the Abeas' automobile repair
activities, or those of the shop next door. This testimony, however,
was contradicted by the testimony of Tito and Pedro Abea, the testi-
mony of Felix Ogando, and by various records indicating that Lamont
Garrison and Tito Abea were in frequent contact by pager and cellular
telephone during the relevant time periods. Although Lamont Garri-
son contends that the district court imposed the two-level enhance-
ment based solely upon the testimony of a government witness who
did not testify at trial, the district court's determination that Lamont
committed perjury when he testified at trial is supported by the testi-
mony of those witnesses who did testify at trial-- witnesses whom
the district court, and presumably the jury, credited. Accordingly, we
cannot say that the district court committed clear error in imposing
the two-level enhancement for obstruction of justice for perjury.

IV.

The Garrisons' final challenges to their convictions and sentences
center on assertions that their respective trial counsel were ineffective
for a variety of reasons. Ineffective assistance of counsel claims are
not properly raised on direct appeal "unless the record conclusively
shows" that defense counsel did not provide effective representation.
United States v. King, 119 F.3d 290, 295 (4th Cir. 1997); see United
States v. Williams, 977 F.2d 866, 871 (4th Cir. 1992). Because the
record below fails to conclusively establish counsels' alleged ineffec-
tiveness, we do not reach these claims on direct appeal. The Garrisons
may choose to present these claims in a subsequent proceeding under
28 U.S.C.A. § 2255 (West Supp. 1999).

V.

For the foregoing reasons, we affirm the convictions and sentences
imposed upon Domingo Nolberto Pena, Ronthany Leo Ward, Lamont
Harold Garrison, and Lawrence Bernard Garrison in all respects.
