AURORA, Colo. - Police and firefighters are trying to enter the booby trapped apartment of the man suspected of gunning down dozens of people at a Colorado movie theater.

Authorities say tripwires, ammunition and jars of accelerant are scattered in James Holmes' Aurora apartment.

Local agencies elicited the help of bomb experts in coming up with a plan to enter the apartment while keeping people safe and preserving evidence inside.

Officials positioned vehicles and personnel around the apartment building.

Aurora police Sgt. Cassidee Carlson told reporters Saturday morning that the first goal is to make the area safe, then remove items from the apartment that could explode.

That includes about 30 shells that will be placed in sand trucks and taken to a disposal site.
