The attorney appointed to represent Pedro Chavez Rodriguez, Jr., has moved for leave to withdraw and has filed briefs 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). Rodriguez has filed a response. The record is insufficiently developed to allow consideration at this time of Rodriguez’s claims of ineffective assistance of counsel; such a claim generally “cannot be resolved on direct appeal when the claim has not been raised before the district court since no opportunity existed to develop the record on the merits of the allegations.” United States v. Cantwell, 470 F.3d 1087, 1091 (5th Cir. 2006) (internal quotation marks and citation omitted). We have reviewed counsel’s briefs and the relevant portions of the record reflected therein, as well as Rodriguez’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, Rodriguez’s motion for appointment of substitute counsel is DENIED, counsel is excused from further responsibilities herein, and the APPEAL IS DISMISSED. See 5th Cir. R. 42.2.
