James Holmes, the gunman who killed 12 people and injured 70 others at an Aurora, Colorado, midnight showing of The Dark Knight Rises in 2012, goes to trial Monday in Arapahoe County District Court. Holmes’ defense concedes he committed the crime, but has pleaded not guilty of murder and attempted murder by reason of insanity. The trial is expected to last for months as prosecutors are aiming for the death penalty and the defense will lobby the jury—11 women and one man, selected from a pool of 9,000—that Holmes was mentally incapable of differentiating between right and wrong.
Holmes, 27, a former graduate student at the University of Colorado, planned and carried out a massacre at the Century 16 movie theater in Aurora on July 20, 2012. Dressed in black and armed with multiple weapons, Holmes tossed tear gas into a packed movie theater and opened fire. His hair had been died red/orange, and according to two federal officials, he referred to himself as the Joker after he was arrested near his car in the theater parking lot. Police authorities found that he’d also booby-trapped his apartment with explosives to inflict additional casualties.
