On July 20, 2012, a gunman, suspected to be James Eagan Holmes, opened fire during the midnight premiere of The Dark Knight Rises in a Cinemark movie theater in Aurora, Colorado, killing 12 people and injuring 58. The suspected gunman, acting alone, entered the theater dressed in protective clothing, set off smoke or gas canisters, then shot into the audience with multiple firearms. The attack is the largest mass shooting in the United States in terms of victims.
The attack occurred in Theater 9 at the Century 16 movie theater (operated by Cinemark) next to the Town Center at Aurora shopping mall. The shooter bought a ticket and walked into the cinema. He then left through an emergency exit, propping it open, went to his car parked behind the exit, dressed in protective clothing and retrieved his guns. He returned through the exit approximately thirty minutes into the film,[8] dressed all in black; he was wearing a ballistic helmet, a tactical ballistic vest, ballistic leggings, a throat protector, a groin protector, a gas mask, and black tactical gloves.
The suspect used two devices to distract the audience members, releasing an irritant or smoke in the cinema, before using a Smith & Wesson AR-15 semi-automatic rifle, a 12-gauge Remington Model 870 shotgun, and a G23 .40 caliber Smith & Wesson Glock handgun to shoot at the crowd in the cinema. A second Glock handgun was found in the suspect's car.
Few in the audience thought Holmes a threat when he first entered the theater. He appeared to be wearing a costume, but others too had dressed up for the movie. Some thought the gunman was pulling a prank until he threw his canisters and began firing. Some present thought the gunman was part of a special effects installation set up for the premiere, and that it was a publicity stunt by the studio or theater.
Around the first gun scene in the movie, the masked gunman threw a canister emitting a gas or smoke which partially obscured the audience's sight. He fired with a shotgun first at the ceiling and then on the audience, only stopping to reload. The first phone calls to emergency services were made at 12:39 a.m. First he shot to the back of the room, and then toward people escaping in the aisles. Some bullets went through the wall hitting people in the neighboring Theater 8, screening the same film.
The police arrived within 90 seconds and apprehended the suspect. The police interviewed over 200 witnesses following the attack. Investigators believe that the shooter acted on his own, and was part of no group.[18] The alleged shooter had bought nearly 7,000 rounds of ammunition in the 60 days prior to the shooting. The guns and ammunition used in the attack had been bought legally, with the guns bought at local gun shops, and the ammunition ordered online.
The police arrested an unresisting Holmes behind the theater next to his car. The responding officers recovered several guns from inside the car and the theater. Per two federal authorities, the suspect had painted his hair red and called himself "The Joker". Holmes is on suicide watch in solitary confinement and due to appear in court on Monday, July 23, 2012.
The shooting injured 70 people, with 10 dying at the scene and 2 in local hospitals.
The injured were treated at Children's Hospital Colorado, Denver Health Medical Center, The Medical Center of Aurora, Parker Adventist Hospital, Rose Medical Center, Swedish Hospital, and University Hospital, as well as at a makeshift hospital set up at the scene of the attack. Uninjured witnesses were taken to Gateway High School for police interviews. The victims were aged 3 months to 51 years old. The Arapahoe County Coroner's Office listed the killed as Jonathan T. Blunk, Alexander J. Boik, Jesse E. Childress, Gordon Cowden, Jessica Ghawi, John T. Larimer, Matthew McQuinn, Micayla Medek, Veronica Moser-Sullivan, Alex M. Sullivan, Alexander Teves and Rebecca Wingo. McQuinn has been presumptively identified. The cause of death in all cases was related to gunshot wounds.
