Both Petric's defense attorneys and prosecutors blamed the crime on the teen's "addiction" to the game Halo 3. His lawyers claimed that the teen had become obsessed with the game after playing it constantly while incapacitated for months following an injury. Pleading an insanity defense, they argued he would forgo food and sleep to play the game for up to 18 hours a day, creating a mental state where he didn't think death was permanent.
