After a jury trial, Leroy Louis Scott, Jr., was convicted of escaping from federal custody, in violation of 18 U.S.C. § 751(a) (1994). The District Court 1 sentenced him to sixteen months’ imprisonment and two years’ supervised release. On appeal, his counsel has filed a brief and moved to withdraw under Anders v. California, 386 U.S. 738, 87 S.Ct. 1396, 18 L.Ed.2d 493 (1967), and Scott has filed a pro se supplemental brief.

We have carefully considered each of the issues raised on appeal-regarding Scott’s speedy-trial rights under the Sixth Amendment and the Speedy Trial Act, his Fifth Amendment right to be free from excessive pre-indictment delay, the alleged variance between the indictment and the jury instructions, the District Court’s re *548 ceipt of hearsay evidence, and his duplicity challenge to the indictment-and we find each argument to be without merit. Additionally, having reviewed the record independently pursuant to Penson v. Ohio, 488 U.S. 75, 109 S.Ct. 346, 102 L.Ed.2d 300 (1988), we have not found any nonfrivolous issues for appeal.

Accordingly, we affirm the judgment of the District Court, and we grant counsel’s motion to withdraw.
