Aurora police: Officers on scene in 60-90 seconds

AURORA, Colo. (AP) -- The police chief in the Denver suburb where a gunman shot 71 people says the suspect was arrested soon after officers arrived.

Aurora Police Chief Dan Oates says hundreds of calls came in starting at 12:39 a.m. MDT Friday and officers were on the scene within 60 to 90 seconds.

He says 24-year-old James Holmes was taken into custody at his white Hyundai parked in back of the theater.

Oates says eventually, 200 officers responded.

The chief says officers found an AR-15 assault rifle -- the civilian form of the M-16 -- a Remington 12-guage shotgun and a .40-caliber Glock handgun in the theater and another identical handgun in the car. Oates says the gunman set off two devices to distract the crowd that released a smoke or an irritant.
