The Federal Public Defender appointed to represent Everardo Puente 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). Puente has filed a response. The record is insufficiently developed to allow consideration at this time of Puente’s claims of ineffective assistance of counsel; such claims generally “cannot be resolved on direct appeal when [they have] not been raised before the district court since no opportunity existed to develop the record on the merits of the allegations.” United States v. Cantwell, 470 F.3d 1087, 1091 (5th Cir. 2006) (internal quotation marks and citation omitted). Our independent review of the record, counsel’s brief, and Puente’s response discloses no nonfrivo-lous issue for appeal. Accordingly, the motion for leave to withdraw is GRANTED, counsel is excused from further responsibilities herein, and the APPEAL IS DISMISSED. See 5th Cir. R. 42.2.
