Counsel appointed to represent Adan Guzman has moved for leave to withdraw and has filed a brief as required by Anders v. California, 386 U.S. 738, 87 S.Ct. 1396, 18 L.Ed.2d 493 (1967). Guzman has filed a response.

Our independent review of the briefs, Guzman’s response, and the record discloses no nonfrivolous issue for appeal. On the other hand, the record is insufficiently developed to permit consideration on direct appeal of the ineffective-assistance-of-counsel claim (IAC claim) possibly raised in Guzman’s response. See United States v. Higdon, 832 F.2d 312, 314 (5th Cir. 1987), cert. denied, 484 U.S. 1075, 108 S.Ct. 1051, 98 L.Ed.2d 1013 (1988). Accordingly, without prejudice to Guzman’s right to file a motion pursuant to 28 U.S.C. § 2255 on an IAC claim, 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. Guzman’s motion to appoint substitute counsel is DENIED.
