Colorado shooting: Bomb squads disarm suspect's booby-trapped apartment
With the help of a robot, Colorado shooting suspect James Holmes' booby-trapped apartment has been largely disarmed. Authorities say he planned to kill whoever entered – most likely a first responder. Also Saturday, those killed in the theater attack began to be publicly identified.

The Colorado shooting suspect planned the rampage that killed 12 and injured dozens of others at a suburban movie theater with "calculation and deliberation," police said Saturday, receiving months of deliveries in advance that authorities believe armed him for battle and were used to rig his apartment with explosives aimed at killing first responders.

"You think we're angry? We sure as hell are angry," Aurora Police Chief Dan Oates said.
Authorities on Saturday were still working to clear dangerous explosive materials from inside James Holmes' suburban Denver apartment, which was booby trapped to kill "whoever entered it," Oates said, noting it would have likely been one of his officers.
Federal authorities detonated one small explosive and disarmed another inside Holmes' apartment with a device that emits a shock wave and water, a law enforcement official told The Associated Press. The official spoke on condition of anonymity, citing the ongoing investigation into the shooting rampage that killed 12 people and wounded 58.

Holmes' apartment appears to have three types of explosives — jars filled with accelerants, chemicals that would explode when mixed together and more than 30 "improvised grenades," the official said.
Oates said Holmes has been preparing the attack for months.
"We've become aware that he had a high volume of deliveries to both his work and home address. We think this explains how he got his hands on the magazine, ammunition," he said. "We also think it begins to explain how he got the materials he had in his apartment."
"What we're seeing here is evidence of some calculation and deliberation," Oates added.
FBI Special agent James Yacone said that while most of the explosives had been rendered safe in Holmes' apartment, "the threat has not been completely eliminated."
"It was an extremely dangerous environment," Yacone said.
Makeshift memorials sprang up for the victims, including a 6-year-old girl, an aspiring sportscaster and a man celebrating his 27th birthday, after police grimly went door to door with a list of those killed in the worst mass shooting in recent U.S. history. Holmes, 24, was arrested early Friday outside the Aurora theater after witnesses say he unleashed gunfire and gas canisters on a crowd of moviegoers watching the midnight showing of the new Batman film, "The Dark Knight Rises."

Federal officials said in a bulletin obtained by The Associated Press that they still hadn't determined a motive for the suspect as families grieved and others waited at hospitals, where seven of the wounded remained in critical condition on Saturday.
In his Saturday radio address, President Barack Obama urged Americans to pray "for the victims of this terrible tragedy, for the people who knew them and loved them, for those who are still struggling to recover."
