AURORA, Colo. (AP) — A gunman wearing a gas mask and black SWAT gear hurled a gas canister inside a crowded movie theater during a midnight showing of the new Batman movie Friday and then opened fire, killing 12 people and wounding nearly 60 others in an attack so bizarre that some moviegoers at first thought they were watching Hollywood special effects.
As smoke from the canister spread, audience members watching "The Dark Knight Rises" at the suburban Denver theater saw the silhouette of a person materialize near the screen, point a gun at the crowd and begin shooting, apparently without a word.
It was one of the deadliest mass shootings in recent U.S. history.
The suspected gunman, identified as James Holmes, a 24-year-old graduate student in neuroscience at the University of Colorado-Denver, was arrested near a car behind the theater.
Authorities gave no motive for the attack. The FBI said there was no indication of ties to any terrorist groups.
"There were bullet (casings) just falling on my head. They were burning my forehead," Jennifer Seeger said, adding that the gunman, dressed like a SWAT team member, fired steadily, stopping only to reload. "Every few seconds it was just: Boom, boom, boom," she said. "He would reload and shoot and anyone who would try to leave would just get killed."
Police said 71 people in all were shot.
Aurora Police Chief Dan Oates said the gunman wore a gas mask, a ballistic helmet and vest as well as leg, groin and throat protectors. He said he had an AR-15 military-style, semi-automatic rifle, a shotgun and two pistols.
While some witnesses said the gunman entered through a side-door emergency exit at the front of the theater, a federal law enforcement official, speaking on condition of anonymity, said Holmes bought a ticket and went into the theater as part of the crowd.
