The Federal Public Defender appointed to represent Chris E. Williams 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). Williams has filed a response. The record is not sufficiently developed to allow us to make a fair evaluation of Williams’s claim of ineffective assistance of counsel; we therefore decline, to consider the claim without prejudice to collateral review. See United States v. Isgar, 739 F.3d 829, 841 (5th Cir.), cert. denied, — U.S. -, 135 S.Ct. 123, 190 L.Ed.2d 94 (2014).

We have reviewed counsel’s brief and the relevant portions of the record reflected therein, as well as Williams’s response. We concur with counsel’s assessment that the appeal presents no nonfrivolous issue for appellate review. Accordingly, the motion for leave to withdraw is GRANTED, counsel is excused from farther responsibilities herein, and *175 the APPEAL IS DISMISSED. See 5th CiR. R. 42.2.
