WASHINGTON -- Federal law enforcement officials say the suspect in last night's deadly shooting in Colorado is James Holmes, a 24-year-old American.
Officials believe Holmes killed a dozen people when he fired into a crowded movie theater in a Denver suburb. He was wearing a gas mask and set off an unknown gas in the theater.
Holmes is in police custody, and the FBI says there is no indication that incident is tied to any terrorist groups.
Holmes was studying neuroscience in a Ph.D. program at the University of Colorado-Denver graduate school. University of Colorado spokeswoman Jacque Montgomery says Holmes was a student until last month. Montgomery says Holmes enrolled in the program in June 2011 and was in the process of withdrawing.
Meanwhile, FBI agents and police used a hook and ladder fire truck to reach Holmes' apartment in suburban Denver, Aurora police Chief Dan Oates said. They put a camera at the end of 12-foot pole inside the apartment, and discovered that the unit was booby trapped.
Authorities evacuated five buildings as they determine how to disarm flammable and explosive material. The apartment is about four miles from the theater.
Holmes graduated from high school in the San Diego area. His family in California said in a statement that their hearts go out to those involved.
The family asked the media to respect their privacy. They say they're cooperating with authorities in San Diego and Aurora, Colo., and are trying to process everything. Holmes graduated from high school in the San Diego area.
San Diego police spokeswoman Andra Brown says there's nothing to suggest the family had any involvement.
