AURORA, Colo. - Multiple police agencies, including a swat team and bomb squad, were outside the apartment complex of a man suspected of killing 12 people and injuring over 50 others at an Aurora movie Theater.

Aurora Police Chief Dan Oates said the apartment is booby trapped with flammable or explosive items.Oates called the devices, "very sophisticated" and "something I've never seen."
