Police use a video camera to look inside an apartment where the suspect in a shooting at a movie theatre lived in Aurora, Colo., Friday, July 20, 2012.
AURORA, Colo. - Police say the apartment of the suspect in a mass shooting at a Denver area movie theater is booby trapped, so they've evacuated five surrounding buildings.
Aurora Police Chief Dan Oates says bomb technicians are determining how to disarm flammable or explosive material in the third-floor apartment. He says police could be there some time.
Oates says pictures from inside the apartment are fairly disturbing and the devices look to be sophisticated.
FBI agents and police used a hook and ladder fire truck and put a camera at the end of 12-foot pole inside the apartment where 24-year-old James Holmes lives.
The apartment is about four miles from the theater where at least 12 people were killed and 50 were wounded.
Police recovered four guns at the theater - one shotgun, two pistols and what is believed to be an assault rifle, a law enforcement source told CBS News correspondent Bob Orr. Authorities also recovered a gas mask.
A law enforcement source said the suspect also had a bullet proof vest, ballistic helmet and military SWAT clothing. Authorities were testing unidentified explosives in his vehicle, though their exact nature is unclear.
The nature of the attack suggests it was well planned. The suspect's vehicle was parked at the rear of the complex, near the emergency exit where he was reported to have entered from.
Oates said there's no evidence of any other attackers. There was also no immediate word of any motive. Federal law enforcement officials are being briefed on the attack, but at this point, there is no indication it is terrorism-related, CBS News senior correspondent John Miller reports.
