The attorney appointed to represent Os-amu John Hack 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). Hack has filed a response. To the extent he is raising a claim of ineffective assistance of counsel, the record does not provide sufficiént detail to allow us to make a fair evaluation of Hack’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. 2014). 1 We have reviewed counsel’s brief and the relevant portions of the record reflected therein, as well as Hack’s response. We concur with counsel’s assessment that the appeal presents no non-frivolous issue for appellate review. 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.
