Police say a gunman barged into a packed auditorium at the Century 16 Movie Theaters at the Aurora Town Center on Friday, set off gas canisters and began shooting into the crowd - picking off people who tried to flee. In addition to the 12 killed, 58 more were injured, with 30 remaining hospitalized and 7 in critical condition with some injuries that could be permanent.
Aurora police arrested 24-year-old James Holmes, a native of San Diego. Investigators were confident he acted alone and were not looking for any other suspects. There was no immediate word of any motive.
Those who survived the attack are sharing their chilling accounts. Two of those survivors told their stories from their hospital beds.
"He was standing literally directly above me. I could feel his boot right next to my head. I just had my face down on the ground and I just stayed as still as I possibly could," said Pierce O'Farrill. "I prayed and I prayed. He fired off a couple more rounds and then he left."
Bullets hit O'Farrill in his leg and shoulder.
Steve Barton is a Connecticut cyclist who was on a cross country bike tour when he stopped in Aurora to see the movie.
"It was cold and calculating definitely. It seemed very methodical, just the rate at which he was firing and how he wasn't really moving positions. It was just like unloading into the crowd," described Barton, a Syracuse University graduate. He was sitting in the middle row when the shooting happened. He was shot in the neck and chest with shotgun pellets.
