The attorney appointed to represent John Allen Walter has moved for leave to withdraw and has filed briefs 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). Walter has filed a response. The record is not sufficiently developed to allow us to make a fair evaluation of Walter’s claims of ineffective assistance of appellate counsel; we therefore decline to consider the claims without prejudice to collateral review. See United States v. Isgar, 739 F.3d 829, 841 (5th Cir. 2014).

We have reviewed counsel’s briefs and the relevant portions of the record reflected therein, as well as Walter’s response. We concur with counsel’s assessment that the appeal presents no nonfrivolous issue for appellate review. Accordingly, counsel’s motions for leave to withdraw are GRANTED, counsel is excused from further responsibilities herein, and the APPEAL IS DISMISSED. See 5th Cir. R. 42.2. Walter’s motion for appointment of new counsel is DENIED. See United States v. Wagner, 158 F.3d 901, 902-03 (5th Cir. 1998).
