Video: Batman shooting: Police confirm suspect and victims The shooter, James Holmes, was arrested shortly after the midnight attack near a car outside the multiplex theatre in Aurora, suburban Denver. At a press conference in Aurora, Aurora police chief Dan Oates said police began to receive "hundreds" of calls starting at 12.39am local time. Officers arrived within a minute and a half. He added that "many, many rounds" were fired in the rampage in which 71 people were shot. Ten people died at the scene and two more in hospital. The police chief said that the apartment is booby trapped with "various incendiary and chemical devices" and five buildings nearby have been evacuated. He described it as an "active and difficult scene" that may take days for officers to deal with. He added: "We're not speculating on motive" but that Holmes surrendered without incident. He appears to have fired the AR-15 assault rifle, the Remington shotgun and one of two .40 calibre Glocks inside of the theatre. At least one person was injured in an adjacent theatre by a bullet that passed through a wall. An emotional Governor John Hickenlooper said: "This is a safe city, in a safe state in a safe country." Mayor Steve Hogan added: "We took a blow today but we will get back on our feet." He urged parents to talk to their children and "let them know this is an isolated incident. It's tragic, it's horrible but it's isolated and we have to talk about it.
