The Federal Public Defender appointed to represent Miguel Augusto Gomez-Torres 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), and United States v. Flores, 632 F.3d 229 (5th Cir. 2011). Gomez-Torres has filed a response and requests new appointed counsel. The record is insufficiently developed to allow consideration at this time of Gomez-Torres’s claims of ineffective assistance of counsel; such claims generally “cannot be resolved on direct appeal when the claim[s] ha[ve] 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). We have reviewed counsel’s brief and the relevant portions of the record reflected therein, as well as Gomez-Torres’s response. We concur with counsel’s assessment that the appeal presents no nonfrivolous issue for appellate review. Accordingly, Gomez-Torres’s motion for new counsel is DENIED, 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.
