The attorney appointed to represent Eugenio Quintero on appeal has filed a motion to withdraw that is incorporated in a brief filed pursuant to 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). Quintero has filed a response. The record is not sufficiently developed to allow us to make a fair evaluation of Quintero’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 Quintero’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.
