Aurora Police Sgt Cassidee Carlson says the booby-trapped flat was rigged “to kill”
Police have entered the Colorado flat of the man suspected of shooting dead 12 people at a Batman film screening and dismantled an incendiary device.
Police spokeswoman Cassidee Carlson said officers had “defeated the first threat” by disarming a trip-wire and an incendiary device.
But she warned that there was a second device, and a controlled explosion might be needed to disarm it.
The flat belongs to James Holmes, suspected of the killings on Friday
