MEMORANDUM **

Raymundo Montenegro Saucedo appeals from his jury-trial conviction and 156-month sentence imposed for conspiracy to possess with intent to distribute heroin in violation of 21 U.S.C. § 846, possession with intent to distribute heroin in violation of 21 U.S.C. § 841(a)(1) and (b)(1)(B), and possession with intent to distribute methamphetamine, in violation of 21 U.S.C. §§ 841(a)(1) and (b)(1)(A).

Pursuant to Anders v. California, 386 U.S. 738, 87 S.Ct. 1396, 18 L.Ed.2d 493 (1967), Saucedo’s counsel has filed a brief stating there are no grounds for relief, along with a motion to withdraw as counsel of record. Saucedo filed a pro se supplemental brief, in which he contended that he was entrapped by the government informant. However, Saucedo never raised *655this defense at trial and it is not properly before this panel for the first time on appeal. See United States v. Davis, 36 F.3d 1424, 1430 (9th Cir. 1994) (internal quotations omitted) (“It is inappropriate for an appellate court to determine whether a defendant was entrapped when such a determination would necessarily entail choosing between conflicting witnesses and judging credibility.”).

Our independent review of the briefs and the record pursuant to Penson v. Ohio, 488 U.S. 75, 80-81, 109 S.Ct. 346, 102 L.Ed.2d 300 (1988), discloses no grounds for relief on direct appeal.

Counsel’s motion to withdraw is GRANTED, and the government’s motion to dismiss is denied.

AFFIRMED.
