James Holmes is accused of opening fire on the crowd, killing 12 people and injuring or maiming 70 others in Aurora, a suburb of Denver.
Holmes appeared like the Joker, with red-orange hair and wearing body armor and carried several guns, including an AR-15 rifle, with lots of ammo. He also wore a gas mask.
Holmes says he was insane at the time of the shootings, and that is his legal defense and court plea: not guilty by reason of insanity. Prosecutors aren’t swayed and will seek the death penalty.
