The Federal Public Defender appointed to represent Cresencio Perez 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). Perez has filed a response in which he challenges his .conviction and sentence. Because the record reflects that Perez knowingly decided not to appeal his conviction, we will not address the issues raised in his response related to his conviction. See United States v. Polanco-Ozorto, 772 F.3d 1053, 1054-55 (5th Cir. 2014). We have reviewed counsel’s brief and the relevant portions of the record reflected therein, as well as Perez’s response to the extent it addresses sentencing issues. We concur with counsel’s assessment that the appeal presents no nonfrivolous issue for appellate review. Accordingly, Perez’s motion for appointment of counsel is DENIED, counsel’s 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.
