UPDATE: CENTENNIAL, Colo. - The man suspected of killing 12 people and wounding 58 others in a shooting spree at a movie theater in Colorado showed little emotion today in his first court appearance.
AURORA, Colo. - Aurora Police believe 24-year-old James Holmes is responsible for the mass shooting at a movie theatre just after midnight Friday morning.
Police say 12 people are dead and 50 injured following a shooting at a movie theatre in Aurora, CO. Officers say the gunman opened fire shortly after midnight local time in a theatre during the showing of the latest Batman movie, "The Dark Knight Rises."
Witnesses tell police that before the gunman started shooting, he released some sort of canister that made a hissing sound, and then gas emerged.
Officials say police, ambulances and emergency crews swarmed the scene after frantic calls started flooding the 911 switchboard.
Police found the gunman near a car behind the theater and took him into custody.
