Jurors have begun deliberating in the trial of Colorado theatre shooter James Holmes.
The panel was deliberating Wednesday over whether Holmes was legally insane when he killed 12 people during a crowded midnight movie premiere three years ago.
Holmes' attorneys say he was in the grips of a psychotic breakdown and couldn't tell right from wrong. Prosecutors say Holmes was legally sane when he methodically planned and carried out the attack, which also left 70 people injured.
Attorneys made their final appeals to jurors Tuesday. The panel must pore over 11 weeks of testimony from more than 250 witnesses.
If jurors find Holmes was legally insane, he'll be committed to a state mental hospital indefinitely. Prosecutors are seeking the death penalty.
