Colorado Theater Shooting Colorado Theater Shooting

A lone gunman tossed tear gas into an Aurora, Colo., movie theater before opening fire at a Friday midnight showing of The Dark Knight Rises, killing at least 12 people and injuring 59 others, CNN reports.

The wounded victims range from 3 months old to 45 years. Some still remain in critical condition.

The suspect, 24-year-old James Holmes, is now in custody and is set to appear in court on Monday. Police, who believe he acted alone, apprehended him in a parking lot behind the Century 16 Movie Theater. "He did not resist. He did not put up a fight," Aurora police spokesman Frank Fania told CNN. Holmes was dressed head-to-toe in protective tactical gear and used an AR-15 rifle, a 12-gauge shotgun and at least one of two .40-caliber handguns recovered at the scene, according to police.

When the police went to search the suspect's home for possible explosive materials or devices, they discovered that it had been fitted with various traps.
