See original story below.

A shooter opened fire at Umpqua Community College in Oregon on Thursday. According to the state's attorney general, 13 people were killed and more than 20 were injured. KATU reports that the shooter has apparently been detained, though no further details have been released. Local fire departments have confirmed to reporters that the situation is no longer being treated as an active shooter incident, further confirming that the suspect has been detained.

Initial reports of an active shooter started showing up on Twitter roughly an hour before the shooter was reported to be detained in some way, with several witnesses describing the chaos. Local authorities are urging residents to stay away from campus, as ATF canine teams search for explosives and ammunition. Students are currently being "bused off campus," with emergency medical crews still assisting the wounded on campus. FBI officials are currently en route to the scene.

Though the shooter has been identified by local authorities as a male in his late 20s, his name has not yet been released to the press. Online reports quoted by the New York Daily News suggest that the shooter may have issued some sort of warning via a post on 4chan on Wednesday, including a reference to Isla Vista shooter Elliot Rodger. Eyewitness accounts quoted by NRToday reveal that the shooter asked potential victims to "stand up and state their religion" before he started firing away.
