Preparing for controlled detonation in Colorado

Police probing a Colorado shooting rampage prepare on Saturday to send in a robot to detonate what they called a sophisticated booby-trap in the apartment of a man suspected of killing 12 people at a screening of the new "Batman" movie.

Authorities gathered around the apartment of 24-year-old James Holmes who was taken into custody outside the theater minutes after the attack.

After his arrest, police found a set of explosives at his home and said his living room was crisscrossed with trip wires connected to what appeared to be plastic bottles containing an unknown liquid.

Cassidee Carlson is with the Aurora Police department.

"There is no timeline. I can't give you an endtime. We're hoping to get in there within the next hour. That's about the only time-- because we have no idea how long any of this is going to take, so I can't put an endtime to it because, of course, I emphasize again the importance of public safety. It's safe right now, with the evacuations; we don't need to rush anything and we're going to do our best and take our time to just keep it as safe as possible."

Authorities have evacuated the area and have brought in scores law enforcement and explosives experts.
