AURORA, Colo. (AP) - Right now authorities in Colorado are trying to determine what prompted a gunman to open fire early Friday morning at a movie theater in a Denver suburb, killing 12 people and leaving at least 38 others injured.
The shooting occurred during a midnight premiere of the latest Batman movie "The Dark Knight Rises.
There was no immediate word on a motive. Right now authorities are checking the apartment of the shooter, but they believe it appears to be "booby-trapped."
The shooter, identified at 24-year-old James Holmes, is in custody. Officials say he has no significant criminal record nor military history. There are multiple reports that Holmes was a student at the University of Colorado Denver Medical Campus. He withdrew in June.
Colorado shooting suspect's family in California says "their hearts go out to those involved."
Pentagon officials say service members are among the casualties in the Colorado shooting.
The violence erupted about 12:30 a.m. MDT as the gunman stood at the front of one of the Century 16 theaters at the Aurora Mall.
"Witnesses tell us he released some sort of canister," Aurora Police Chief Dan Oates said at a news conference. "They heard a hissing sound and some gas emerged and the gunman opened fire,"
Witness Hayden Miller told KUSA-TV that he was inside Theater 16 and heard several shots.
"Like little explosions going on and shortly after that we heard people screaming," he told the station.
Hayden said at first he thought it was part of a louder movie next door. But then he saw "people hunched over leaving theater."
Another witness said the gunman "would reload and shoot and anyone who would try to leave would just get killed."
Aurora is located on the southeast outskirts of Denver, about 10 miles from downtown.
President Obama, during a campaign stop in Florida Friday morning said, "We are going to stand by our neighbors in Colorado during this extraordinarily difficult time. There will be other days for politics. This is a day for prayer and reflection."
After the addressing the crowd in Ft. Myers, the president returned to the White House where he will be monitoring developments throughout the day. There are reports he may address the nation later today.
