University spokeswoman Jacque Montgomery says 24-year-old Holmes, who police say is the suspect in a mass shooting at a Colorado movie theater, was studying neuroscience in a Ph.D. program at the University of Colorado-Denver graduate school. Holmes is suspected of shooting into a crowd at a movie theater killing at least 12 people and injuring dozens more, authorities said.AURORA, Colo. – 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.
