State of Arizona v. Luis Armando Vargas

Summary

The court held that a defendant asserting cumulative prosecutorial misconduct need not separately argue fundamental error for every alleged incident to preserve those incidents for appellate review. A properly developed claim must identify the cumulative error, cite the record and supporting authority, and explain why the alleged misconduct collectively denied a fair trial. The court vacated the appellate decision concerning the cumulative-misconduct claim and remanded for reconsideration under that framework.
