How has the Court considered an appeal from an appellant who made a 9-1 call to report a sexual assault?

Appellant filed a timely appeal. We appointed counsel to represent him on appeal, and after examination of the record, counsel filed an opening brief raising no issues and asking this court to independently review the record. (People v. Wende (1979) 25 Cal.3d 436.) On April 17, 2015, we advised appellant he had 30 days within which to personally submit any contentions or issues he wished us to consider. He filed a supplemental letter brief in which he contends (1) his Sixth Amendment right to confront his accuser was violated, (2) the 9-1-1 call was inadmissible hearsay, and (3) his attorney provided ineffective assistance.
