July 19, 2012 - Holmes attends the midnight showing of "The Dark Knight Rises" at the Century Aurora 16 Multiplex Theater in Aurora, Colorado. Holmes enters theater #9 but soon exits through a rear door on the right side of the screen, leading to a parking lot. He leaves the door propped open and returns through it, according to a law enforcement source involved in the investigation.
The gunman is "dressed head-to-toe in protective gear"- a ballistic helmet, protective gear for his legs, throat and groin, black gloves and a gas mask. He props open the door, before throwing two tear gas canisters into the theater. After both canisters explode, witnesses say he started shooting, first at the ceiling and then at the crowd. Police say he used an AR-15 rifle, a 12-gauge shotgun and at least one of two .40-caliber handguns police recovered at the scene.
