The attorney appointed to represent Craig Pipps 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). Pipps has filed a response. The record is not sufficiently developed to allow us to make a fair evaluation of Pipps’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 Pipps’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 further responsibilities herein, and the APPEAL IS DISMISSED. See 5th Cir. R. 42.2. Pipps’s request to relieve counsel and to proceed *405 pro se is DENIED as untimely. See United States v. Wagner, 158 F.3d 901, 902-03 (5th Cir. 1998).
