AURORA, Colo (AP) Perhaps remembering the incident in July, when a man shot dozens of people in an Aurora, Colorado movie theater, shoppers and employees got nervous when they heard a gunshot. Police arrived and cleared the store and no injuries were reported. Witnesses say a man wearing a black ski mask entered the store and fired one shot into the ceiling. He was last seen running away. Police searched nearby neighborhoods but the person is still at large. Police are investigating the incident as an attempted robbery.
