But the psychiatrist said Holme's mental illness led him to open fire.
Dr. Jeffrey Metzner's finding has not changed: He concluded that Holmes knew right from wrong when he killed 12 people and injured 70 others, therefore meeting the legal definition of sanity under Colorado law. But Metzner also says the attack would not have happened if not for Holmes' mental illness.
The defense hopes that will persuade jurors to sentence Holmes to life in prison without parole instead of to death.
