PER CURIAM:

Nyron Joel Nichols was convicted by a jury of 

conspiracy to possess with intent to distribute fifty grams or 

more of cocaine base, and a measurable quantity of cocaine 

powder, in violation of 21 U.S.C. §§ 841(a)(1), 846 (2006), 

three counts of distributing a measurable quantity of cocaine 

powder, in violation of 21 U.S.C. § 841(a)(1), (b)(1)(C), and 

possessing a firearm in furtherance of a drug trafficking 

offense and/or using or carrying a firearm during and in 

relation to a drug trafficking crime, in violation of 18 U.S.C. 

§ 924(c)(1)(A) (2006). The district court imposed a life 

sentence on the offenses involving cocaine base, with concurrent 

240-month sentences on the offenses involving cocaine powder, 

and a consecutive sixty-month sentence on the firearm offense. 

We affirm.

On appeal, Nichols first contends that the indictment 

was defective. Our review of the record leads us to conclude 

that Nichols’ claim is without merit, and in any event, because 

Nichols failed to assert this claim before trial, it is waived. 

Fed. R. Crim. P. 12(b)(3), (e). 

Nichols next contends that the district court’s 

forfeiture order was improperly entered because none of the

offenses of conviction were forfeiture related, and the jury did 

not decide the forfeiture issue. A defendant who is convicted 
3

of a drug trafficking offense shall forfeit property obtained as 

a result of the offense. 21 U.S.C. § 853 (a)(1); United States 

v. McHan, 345 F.3d 262, 267-68 (4th Cir. 2003). Moreover, 

although a defendant has a right to have a jury decide a 

forfeiture issue, the defendant must affirmatively assert that 

right. Fed. R. Crim. P. 32.2(b)(5). After reviewing the 

record, we conclude that Nichols was convicted of an offense 

requiring forfeiture of property obtained in connection with 

that offense, and waived his right to have a jury decide the 

forfeiture issue. 

Next, Nichols challenges the sufficiency of the 

evidence supporting his convictions. We review de novo a 

district court’s denial of a Fed. R. Crim. P. 29 motion for a 

judgment of acquittal. United States v. Green, 599 F.3d 360, 

367 (4th Cir.), cert. denied, 131 S. Ct. 271 (2010). A 

defendant challenging the sufficiency of the evidence “bears a 

heavy burden.” United States v. Beidler, 110 F.3d 1064, 1067 

(4th Cir. 1997). A jury verdict must be sustained “if, viewing 

the evidence in the light most favorable to the prosecution, the 

verdict is supported by ‘substantial evidence.’” United States 

v. Smith, 451 F.3d 209, 216 (4th Cir. 2006). Substantial 

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.” Id. (internal 
4

quotation marks omitted). “[T]he jury, not the reviewing court, 

weighs the credibility of the evidence and resolves any 

conflicts in the evidence presented.” Beidler, 110 F.3d at 1067 

(internal quotation marks omitted). “Reversal for insufficient 

evidence is reserved for the rare case where the prosecution’s 

failure is clear.” Id. (internal quotation marks omitted).

To establish Nichols’ guilt under 21 U.S.C. § 846, the 

evidence must show that: (1) an agreement to possess and 

distribute cocaine powder and cocaine base existed between two 

or more people; (2) Nichols knew of the conspiracy; and (3) 

Nichols knowingly and voluntarily became a part of the 

conspiracy. United States v. Kellam, 568 F.3d 125, 139 (4th 

Cir.), cert. denied, 130 S. Ct. 657 (2009). To establish 

Nichols’ guilt under 21 U.S.C. § 841(a)(1), the evidence must 

show that: (1) Nichols possessed cocaine powder and cocaine 

base; (2) he had knowledge that he possessed cocaine powder and 

cocaine base; and (3) he intended to distribute the cocaine 

powder and cocaine base. United States v. Randall, 171 F.3d 

195, 209 (4th Cir. 1999). Our review of the record leads us to 

conclude that the evidence overwhelmingly established that 

Nichols was guilty beyond a reasonable doubt of the drug 

offenses. 

To establish Nichols’ guilt under 18 U.S.C. § 924(c), 

the evidence must show that Nichols: (i) committed a drug 
5

trafficking crime; and (ii) possessed a firearm in furtherance 

of that crime. 18 U.S.C. § 924(c)(1)(A). As previously noted, 

Nichols committed several drug trafficking offenses. However, 

whether a firearm furthered, advanced, or helped forward one of 

Nichols’ drug trafficking crimes is a question of fact. United 

States v. Lomax, 293 F.3d 701, 705 (4th Cir. 2002). After 

reviewing the record, we conclude that the evidence likewise 

overwhelmingly established that Nichols was guilty beyond a 

reasonable doubt of the § 924(c) offense. 

Nichols next claims that several items of evidence 

were prejudicial and improperly admitted at trial. We review a 

district court’s evidentiary rulings for abuse of discretion. 

United States v. Blake, 571 F.3d 331, 350 (4th Cir. 2009), cert. 

denied, 130 S. Ct. 1104 (2010). A district court abuses its 

discretion when its decision to admit evidence was arbitrary and 

irrational. United States v. Weaver, 282 F.3d 302, 313 (4th 

Cir. 2002). A district court’s evidentiary rulings are subject 

to review for harmless error under Fed. R. Crim. P. 52. United 

States v. Abu Ali, 528 F.3d 210, 231 (4th Cir. 2008). Evidence 

is unfairly prejudicial when “there is a genuine risk that the 

emotions of a jury will be excited to irrational behavior, and 

this risk is disproportionate to the probative value of the 

offered evidence.” United States v. Williams, 445 F.3d 724, 730 

(4th Cir. 2006) (internal quotation marks, citation, and 
6

alteration omitted). Our review of the record leads us to 

conclude that the district court did not abuse its discretion in 

admitting the challenged evidence. 

Nichols next claims that the Government committed 

prosecutorial misconduct in offering perjured testimony. In 

support of his claim that the Government’s witnesses perjured 

themselves, he points to alleged inconsistencies between the 

witnesses’ trial testimony and various other pieces of evidence 

in the case. Despite Nichols’ effort to characterize this claim 

as one of prosecutorial misconduct, it is, at bottom, nothing 

more than an attack on the credibility of the Government’s 

witnesses. By convicting Nichols, however, the jury found that 

the Government’s witnesses were credible, and we do not review 

the jury’s credibility determinations on appeal. United States 

v. Wilson, 484 F.3d 267, 283 (4th Cir. 2007).

Nichols next claims that the incarcerated witnesses 

that testified at his trial were all kept in the same holding

cell at the courthouse, thereby giving them the opportunity to 

discuss and coordinate their testimony, in violation of the Fed. 

R. Evid. 615. Federal Rule of Evidence 615 provides in part that 

“[a]t the request of a party the court shall order witnesses 

excluded so that they cannot hear the testimony of other 

witnesses, and it may make the order of its own motion.” We 

conclude that nothing in the rule requires that witnesses be 
7

separated before or after their testimony. Accordingly, we find 

Nichols’ claim without merit. 

Nichols next claims that the Government violated his 

constitutional rights by failing to turn over witness statements

and other evidence that was allegedly exculpatory in nature. To 

establish a violation pursuant to Brady v. Maryland, 373 U.S. 83 

(1963), a defendant must show that the Government withheld 

evidence that was favorable to the defendant and that was 

material as to his guilt or innocence. Id. at 87. After 

reviewing the record, we conclude that Nichols has not 

established that the Government failed to turn over exculpatory 

evidence.

Nichols also argues that his sentence is procedurally 

and substantively unreasonable. This Court reviews a sentence 

for reasonableness, using an abuse of discretion standard of 

review. Gall v. United States, 552 U.S. 38, 50 (2007). The 

first step in this review requires the court to ensure that the 

district court committed no significant procedural error. 

United States v. Evans, 526 F.3d 155, 161 (4th Cir. 2008). 

Procedural errors include “failing to calculate (or improperly 

calculating) the Guidelines range or failing to consider the § 

3553(a)factors.” United States v. Carter, 564 F.3d 325, 328 

(4th Cir. 2009) (internal quotation marks omitted). The 

district court must make an individualized assessment based on 
8

the facts presented by applying the relevant § 3553(a) factors 

to the circumstances of the case. Gall, 552 U.S. at 51. The 

court then considers the substantive reasonableness of the 

sentence, taking into account the totality of the circumstances. 

Id.

Nichols challenges the district court’s determination 

of the drug weight attributable to him, and claims that it 

considered unreliable evidence in making its determination. A 

district court’s finding regarding drug weights is factual in 

nature and is therefore reviewed for clear error. United States 

v. Fletcher, 74 F.3d 49, 55 (4th Cir. 1996). In conducting this 

review, we give due regard to the district court's opportunity 

to judge the credibility of witnesses. 18 U.S.C. § 3742(e) 

(2006). Credibility determinations therefore receive deference 

unless they are without support in the record. United States v. 

Brown, 944 F.2d 1377, 1379-80 (7th Cir. 1991). Moreover, a 

district court is permitted to consider any relevant and 

reliable evidence before it imposes sentence. United States v. 

Bowman, 926 F.3d 380, 381 (4th Cir. 1991). After reviewing the 

record, we conclude that the district court properly grouped the 

drug counts and did not commit clear error in determining the 

drug weights attributable to Nichols. 

Nichols next challenges the district court’s finding 

that he obstructed justice, warranting a two-level enhancement 
9

to his offense level. We review a district court’s factual 

findings, including those that serve as a basis for an 

obstruction of justice enhancement under U.S. Sentencing 

Guidelines Manual (“USSG”) § 3C1.1, for clear error. United 

States v. Kiulin, 360 F.3d 456, 460 (4th Cir. 2004). We review

the district court’s legal interpretation of the Sentencing 

Guidelines de novo. United States v. Dawkins, 202 F.3d 211, 214 

(4th Cir. 2000). 

A two-level enhancement in a defendant’s offense level 

is authorized if the defendant attempts to suborn perjury, or 

unlawfully influences, or attempts to influence a witness in 

connection with a sentencing hearing. USSG § 3C1.1, cmt. n. 

4(a), (b). We find that the district court properly determined 

that Nichols had obstructed justice, warranting the two-level 

enhancement in his offense level. 

Nichols next argues that the district court improperly 

found that he had a leadership role in the drug conspiracy, 

warranting a three-level enhancement to his offense level. 

Under USSG § 3B1.1(b), a three-level enhancement is authorized 

“[i]f the defendant was a manager or supervisor (but not an 

organizer or leader) and the criminal activity involved five or 

more participants or was otherwise extensive.” The enhancement 

under § 3B1.1(b) is justified if the defendant supervises at 

least one person, and the criminal activity involved five or 
10

more participants. United States v. Bartley, 230 F.3d 667, 673 

(4th Cir. 2000). Our review of the record leads us to conclude 

that the district court properly applied USSG § 3B1.1(b), and 

correctly increased Nichols offense level by three levels.

Accordingly, we conclude that the district court 

properly calculated Nichols’ Guidelines range, considered the 

parties’ arguments, made an individualized assessment on the 

facts presented, and adequately explained the reasons for the 

chosen sentence. Thus, Nichols’ sentence was procedurally 

reasonable. 

Nor was the sentence imposed substantively 

unreasonable. A sentence within the properly calculated 

Guidelines range is presumptively reasonable. United States v. 

Allen, 491 F.3d 178, 193 (4th Cir. 2007). Here, we find that 

the district court correctly determined that Nichols’ Guidelines

range was life imprisonment, and that Nichols has failed to 

rebut the presumption of reasonableness accorded a sentence 

within the Guidelines. 

Nichols also claims that the sixty-month sentence for 

the § 924(c) offense was improperly imposed because he received 

a higher mandatory minimum sentence on a different count of 

conviction. Nichols’ argument is foreclosed by the Supreme 

Court’s recent decision in Abbott v. United States, 131 S.Ct. 18 
11

(2010). Finally, Nichols’ argument that twelve jurors were not 

present at all times during trial is without merit.

Accordingly, we affirm the district court’s judgment. 

We deny Nichols’ motion to file a pro se supplemental brief. We 

dispense with oral argument because the facts and legal 

contentions are adequately presented in the materials before the 

court and argument would not aid the decisional process.
