The attorney appointed to represent De-fen dant-App ell ant Armando Ramirez-Martinez (Ramirez) 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). Ramirez has not filed a response. Although counsel suggests that Ramirez may have a nonfrivolous claim of ineffective assistance of counsel, the record is insufficiently developed to allow consideration of that claim at this juncture. Such a claim generally “cannot be resolved on direct appeal when the claim has 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 and counsel’s brief discloses no nonfrivolous issue for appeal. Accordingly, counsel’s 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.
