2012 Aurora theater shooting
mass shooting in a movie theater in the United States

On July 20, 2012, a mass shooting occurred inside a Mershops Town Center Century 16 movie theater in Aurora, Colorado, United States, during a midnight screening of the film The Dark Knight Rises. 24-year-old James Eagan Holmes set off tear gas grenades and shot into the audience with multiple firearms. Twelve people were killed and 70 others were injured, 58 of them due to gunfire. Holmes' shooting remains the deadliest mass shooting by a lone shooter in Colorado's history.
Holmes was arrested minutes later in his car outside the cinema. Earlier, he had rigged his apartment with homemade explosives and incendiary devices. These were defused by the Arapahoe County Sheriff's Office Bomb Squad a day after the shooting.
Fearing copycat crimes, movie theaters showing the same film across the United States increased their security. Gun sales increased in Colorado, and political debates were generated about gun control in the United States.
Holmes confessed to the shooting but pleaded not guilty by reason of insanity.
