WTRF.com UPDATE: Colo. Police Still Working on Theater Shooting Suspect's Apartment

AURORA, Colo. (AP) -

Police in Aurora, Colo. say they have disarmed a trip wire and an explosive device as they prepare to enter the booby-trapped apartment of the man suspected of gunning down dozens of people at a movie theater Friday.

FBI agents and police discovered it was booby-trapped with trip wires when they used a camera on a pole to look inside. Firefighters are monitoring the building for gases in an effort to determine what chemicals 24-year-old James Holmes might have used in his traps.

Photos of the apartment appear to show jars full of ammunition and liquid. Police plan to try to enter sometime today.

Late Friday night, police grimly went door to door notifying families of the 12 victims killed in the worst mass shooting in the U.S. in recent years. Another 58 people were injured either by gunfire or amid the chaos of people trying to flee the theater in Aurora, Colo. Eleven of the wounded are listed in critical condition.

Mourners are remembering the victims as names begin to emerge. A memorial Mass was held at the Queen of Peace Roman Catholic church in Aurora last night and a makeshift memorial of candles and flowers has sprung up near the theater.

The suspect's stellar academic record, apparent shy demeanor and lack of a criminal background is making the attack even more difficult to fathom.

The new Batman movie, the last in the trilogy starring Christian Bale, opened worldwide yesterday with midnight showings in the U.S.
