Movie Massacre: A Search For Clues

Aurora police have disarmed the trip wire and the first explosive device in the apartment of the suspect in a movie theater shooting.

Aurora police Sgt. Cassidee Carlson says the booby trap was set up to kill the person opening the door.

In her words: "This is some serious stuff that our team is dealing with."

Carlson says there are other devices that need to be disarmed but authorities are reassessing the scene.

She says it's still possible that the team has to detonate the explosives, which could cause a loud boom and fire, but people will be told about it.

The suspect, James Holmes, lives in the third-floor apartment.
