James Holmes Identified As 24-Year-Old Suspect In Denver Shootings (PHOTOS, LIVEBLOG)

The suspect in the Denver movie theater shooting, who allegedly killed a reported 12 people and injured at least 38 at a midnight screening of "The Dark Knight Rises," has been identified as James Holmes.

Holmes is reportedly a 24-year-old white American male, the Associated Press reported on Friday morning. The young man opened fire around 12:30 a.m. MDT Friday morning at the Century Aurora 16 movie theater in Aurora, Colo.

Moviegoers told the AP that Holmes released some sort of smoke and, at first, they believed the attack was part of the show. He reportedly entered through an exit door at the front of the theater, threw tear gas and then began shooting.

According to CBS News, authorities have found no evidence to suggest the incident was terrorism-related. Holmes was not on any watch list that could have alerted authorities that he was dangerous, NBC reported. He also has no military history.

Police found four guns at the theater including two pistols, a rifle and a shotgun.

Holmes was apprehended by police in the movie theater parking lot and did not resist arrest. The car he was driving had Tennessee license plates.

A San Diego woman who identified herself as James Holmes' mother told ABC News that she was unaware of the shooting when she first awoke Friday morning and had not yet been contacted by authorities. She did, however, express concern that her son was involved in the shooting.

"You have the right person," she told ABC News, speaking on what ABC deemed gut instinct. "I need to call the police... I need to fly out to Colorado."

Holmes had not had any previous run-ins with the law, other than a "minor" traffic ticket in 2011, police spokesman Frank Fania told "Today."

CBS News correspondent Bob Orr reported that police found Holmes' residence "booby-trapped" and discovered "buckets of extra ammunition" and some kind of chemical in his home. Police had the apartment building evacuated.

Thus far, Holmes appears to have been the lone gunman.
