The attorney appointed to represent William Rafael Rivera on appeal has requested 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). Rivera has filed a response. Our independent review of the brief, Rivera’s response, and the record discloses no non-frivolous issue for appeal. The record is insufficiently developed to allow consideration of Rivera’s claims of ineffective assistance of counsel. See United States v. Higdon, 832 F.2d 312, 313-14 (5th Cir. 1987). 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.
