The death toll from an early morning shooting rampage is currently at 12 with a total of 50 people who were injured by gunshot wounds, shrapnel, and chemical exposure. The shooter, a man in his 20's, has been captured. According to Huffington Post, children as young as 3-months-old were injured in the unexpected attack that occurred during the "The Dark Knight Rises."

From CBS News:

Colo. A gas mask-wearing gunman opened fire early Friday at a suburban Denver movie theater, leaving at least 12 people dead and 50 others injured, police said.

The violent and chaotic scene erupted about 12:30 a.m. local time as a gunman, identified as 24-year-old James Holmes, stood at the front of one of the Century 16 theaters at the Aurora Mall where the latest Batman movie "The Dark Knight Rises" was playing, police said.

"Witnesses tell us he released some sort of canister. They heard a hissing sound and some gas emerged and the gunman opened fire," Oates said at a news conference.

Police, ambulances and emergency crews swarmed on the scene after frantic calls started flooding the 911 switchboard, officials said.

Officers found Holmes near a car behind the theater.

Police recovered four guns at the theater - one shotgun, two pistols and what is believed to be an assault rifle, a law enforcement source told CBS News correspondent Bob Orr. Authorities also recovered a gas mask.

Oates said there's no evidence of any other attackers. There was also no immediate word of any motive. Federal law enforcement officials are being briefed on the attack, but at this point, there is no indication it is terrorism-related, Miller reports.

The suspect spoke of "possible explosives in his residence. We are dealing with that potential threat," Oates said. Police were at the Denver-area apartment and had evacuated other residents of the building. Oates did not say whether any explosives had been found, but Orr reports that Holmes' residence was "booby trapped" and police can see what looks like "buckets of extra ammunition" and some kind of chemicals, according to a law enforcement source.
