James Eagan Holmes is an American mass murderer responsible for the 2012 Aurora, Colorado shooting in which he killed 12 people and injured 70 others (62 directly and eight indirectly) at a Century 16 movie theater on July 20, 2012. He had no known criminal background before the shooting occurred. Holmes booby-trapped his apartment with explosives before the shooting, which were defused one day later by a bomb squad.

Holmes was arrested shortly after the shooting and was jailed without bail while awaiting trial. Following this, he was hospitalized after attempting suicide several times while in jail. Holmes entered a plea of not guilty by reason of insanity, which was accepted. His trial began on April 27, 2015, and on August 24 he was sentenced to 12 consecutive life sentences plus 3,318 years without parole
