OPINION

PER CURIAM: 

Isaac Irwin Davis was convicted by a jury of one count of conspiracy to possess and distribute cocaine powder and cocaine base, 21

U.S.C. § 846 (1994), for which he was sentenced to 151 months

imprisonment. Davis appeals, claiming that the government’s evidence was insufficient to support his conviction and that the district

court clearly erred in determining the quantity of drugs attributable to

him at sentencing. 

We find that sufficient evidence existed to support Davis’ conviction for conspiracy. To prove a drug conspiracy, the government must

establish: (1) an agreement to distribute existed between two or more

persons; (2) the defendant knew of the conspiracy; and (3) the defendant knowingly and voluntarily became part of the conspiracy. United

States v. Burgos, 94 F.3d 849, 857 (4th Cir. 1996) (en banc). With

respect to the last element, the government need not prove that the

defendant knew the particulars of the conspiracy or all of his coconspirators. Id. at 858. The evidence need only establish a slight connection between the defendant and the conspiracy to support the conviction. United States v. Seni, 662 F.2d 277, 285 n.7 (4th Cir. 1981).

Finally, the testimony of a defendant’s accomplices, standing alone

and uncorroborated, can provide an adequate basis for conviction.

United States v. Burns, 990 F.2d 1426, 1439 (4th Cir. 1993). Several

of Davis’ co-conspirators testified at trial and connected him to the

conspiracy. Davis’ challenges to the credibility of these witnesses are

not subject to review by this court. United States v. Saunders, 886

F.2d 56, 60 (4th Cir. 1989). 

We also find that the district court’s factual finding concerning the

amount of drugs attributable to Davis was not clearly erroneous.

United States v. Randall, 171 F.3d 195, 210 (4th Cir. 1999) (stating

standard). Based on evidence adduced at trial, the Government proved

the quantity (nine kilograms) by a preponderance of the evidence.

United States v. Gilliam, 987 F.2d 1009, 1013 (4th Cir. 1993) (stating

standard). 

Accordingly, we affirm Davis’ conviction and sentence. We dispense with oral argument because the facts and legal contentions are

2 UNITED STATES v. DAVIS
adequately presented in the materials before the court and argument

would not aid in the decisional process.
