If jurors were to find that Holmes was insane, he would be committed indefinitely to the state hospital. If doctors there ever concluded Holmes' sanity had been restored, he could one day be released, but that is considered unlikely.
Law enforcement officers have testified that Holmes planned the attack for months, stockpiling guns and ammunition. They also say he elaborately booby-trapped his apartment with bombs designed to explode and divert police and fire crews from the theater.
Prosecutors want to use that evidence to undermine the insanity claim by showing the attack was meticulously planned and that he knew it was wrong.
