The attorney appointed to represent Jose Antonio Covarrubias has moved for leave to withdraw and has filed a brief in accordance with Anders v. California, 386 U.S. 738, 87 S.Ct. 1396, 18 L.Ed.2d 493 (1967). Our independent review of the record, counsel’s brief and supplemental brief, and Covarrubias’s response and supplemental response shows that there are no nonfrivolous issues for appeal. The record is insufficiently developed to allow consideration on direct appeal of Covarru*727bias’s claim of ineffective assistance of counsel. See United States v. Higdon, 832 F.2d 312, 314 (5th Cir. 1987). Accordingly, without prejudice to Covarrubias’s right to file a motion pursuant to 28 U.S.C. § 2255, the motion for leave to withdraw is GRANTED, counsel is excused from further responsibilities herein, and this appeal is DISMISSED. See 5th Cir. R. 42.2.
