Bomb experts hope they will soon be able to enter the booby-trapped apartment of the suspect in the mass shooting at a screening of the new Batman film at a cinema in Denver, Colorado.
Police in the suburb of Aurora said the first goal is to make the area safe by removing the trip wire, which may include a controlled detonation that causes a loud boom and possibly a fire. Authorities said they will alert people before that happens.
They then plan to remove items from the apartment which could explode, including about 30 shells that will be placed in sand trucks and taken to a disposal site.
Police say they do not have a timeframe because they want to be careful and not rush.
