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.

A federal law enforcement official says the suspect, identified by other federal law enforcement officials as James Holmes, also used a gas canister in the attack in a movie theater in the Denver suburb of Aurora, Colo. The official spoke on the condition of anonymity to discuss the ongoing investigation.

Officials believe Holmes, who was wearing a gas mask during the attack, killed a dozen people when he open fired in the crowded theater.

Investigators from the Bureau of Alcohol, Tobacco, Firearms and Explosives, along with other local, state and federal law enforcement officials, are investigating the overnight attack.

Colorado suspect just withdrew from med school

The suspect in a mass shooting at a Colorado movie theater dropped out of medical school last month.

Spokeswoman Jacque Montgomery says 24-year-old James Holmes was a student at the University of Colorado School of Medicine in Denver until last month. She did not know when he started school or why he withdrew.

Holmes is accused of killing a dozen people when he fired into a crowded movie theater in the Denver suburb of Aurora. He was wearing a gas mask and set off an unknown gas in the theater.

Holmes is in police custody, and the FBI says there is no indication the attack is tied to any terrorist groups.
