Before MELLOY, HANSEN, and COLLOTON, Circuit Judges.
                           ___________

PER CURIAM.

       Jaoquin David Caballero appeals his conviction and sentence imposed by the
district court1 after a jury found him guilty of conspiring to distribute 500 grams or
more of a mixture containing methamphetamine, in violation of 21 U.S.C. § 846, and
knowingly and intentionally distributing or aiding and abetting the distribution of
approximately 218.93 grams of methamphetamine, in violation of 21 U.S.C.

      1
       The Honorable Linda R. Reade, United States District Judge for the Northern
District of Iowa.
§ 841(a)(1). Caballero’s counsel has filed a motion to withdraw and a brief under
Anders v. California, 

(1967), arguing the district court erred in basing
Caballero’s relevant drug quantity on a co-conspirator’s uncorroborated testimony.

       We conclude that the district court did not clearly err in determining the drug
quantity attributable to Caballero. See United States v. Santana, 

, 864
(8th Cir. 1998) (determination of drug quantity is reviewed for clear error). The trial
testimony from a special agent and one of Caballero’s co-conspirators, which the
district court was entitled to credit, amply supports the court’s drug-quantity finding.
See Anderson v. City of Bessemer City, 

, 575 (1985) (findings based on
credibility determinations are virtually never clear error); United States v. Sarabia-
Martinez, 

, 450 (8th Cir. 2002) (sentencing court may determine drug
quantity based on testimony of co-conspirator alone); United States v. Patterson, 

, 790-91 (8th Cir. 2001) (court may consider drug transactions which were
part of regular pattern or scheme of drug activity); United States v. Padilla-Pena, 

, 467-68 (8th Cir. 1997) (sentencing judge who presided over trial was
entitled to base findings of fact on trial record).

      We have carefully reviewed the record under Penson v. Ohio, 

, 80
(1988), and have found no nonfrivolous issues. Accordingly, we grant counsel’s
motion to withdraw, and we affirm.
                      ______________________________
