AURORA, Colo. (AP) -- The Aurora police chief says the suspect in the movie theater shooting set up booby traps in his apartment specifically to kill a police officer who might have opened the door.
Chief Dan Oates says "we sure as hell are angry" at that.
At a Saturday news conference, he also tried to head off a mental incompetence defense by saying suspect James Holmes was deliberate and calculating in receiving numerous commercial deliveries to his home and workplace over the past four months.
He says that explains all the ammunition Holmes had.
Oates says the major threat has been removed from the apartment, but an FBI agent says some dangers still remains, though families should be allowed back into their apartments by Sunday.
