    UNITED STATES of America, Appellee, v. Juan Carlos Contreras TAFOLLA, also known as Juan Mendoza, Appellant.
    No. 06-1062.
    United States Court of Appeals, Eighth Circuit.
    Submitted: May 1, 2007.
    Filed: May 3, 2007.
    Jason T. Griess, U.S. Attorney’s Office, Des Moines, IA, for Appellee.
    Juan Carlos Contreras Tafolla, Des Moines, IA, pro se.
    Before WOLLMAN, MURPHY, and BYE, Circuit Judges.
   [UNPUBLISHED]

PER CURIAM.

A jury found Juan Carlos Contreras Tafolla guilty of four methamphetamine-trafficking offenses, and the district court sentenced him to 180 months in prison and 5 years of supervised release. On appeal, his counsel has filed a brief under Anders v. California, 386 U.S. 738, 87 S.Ct. 1396, 18 L.Ed.2d 493 (1967), and has moved to withdraw, and Tafolla has filed a pro se supplemental brief. They argue that the evidence was insufficient, but we conclude that the evidence, which must be viewed in the light most favorable to the government, was sufficient for the jury to find the elements of each of the crimes beyond a reasonable doubt. See United States v. Sanchez-Garcia, 461 F.3d 939, 945 (8th Cir.2006) (standard of review). After reviewing the record independently pursuant to Penson v. Ohio, 488 U.S. 75, 109 S.Ct. 346, 102 L.Ed.2d 300 (1988), we conclude that there are no non-frivolous issues. Accordingly, we affirm the judgment of the district court, and we grant counsel’s withdrawal motion. 
      
      . The Honorable James E. Gritzner, United States District Judge for the Southern District of Iowa.
