Experts disarm suspect's apartment

US police have begun the intricate process of disarming booby traps in the apartment of the suspect behind the Colorado cinema shootings, hoping to find clues to the motive for the rampage without causing an explosion that could destroy key evidence.

Scores of law enforcement officials, including bomb squad technicians and dozens of federal agents, removed one trip wire and one explosive device inside James Holmes's apartment today, and "other devices" are in there, Sergeant Cassidee Carlson said.
