The Federal Public Defender appointed to represent Jamison Ross Ellis 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). Ellis has filed a response, in which he requests new appointed counsel. The record is not sufficiently developed to allow us to make a fair evaluation of Ellis’s claims of ineffective assistance of counsel; we therefore decline to consider the claims without prejudice to *277 collateral review. See United States v. Isgar, 739 F.3d 829, 841 (5th Cir. 2014).

We have reviewed counsel’s brief and the relevant portions of the record reflected therein, as well as Ellis’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, Ellis’s motion for appointment of new counsel is DENIED, counsel is excused from further responsibilities herein, and the APPEAL IS DISMISSED. See 5th Cir. R. 42.2.
