(FOX NEWS)- The gunman who killed at least nine people and wounded seven at Umpqua Community College in Roseburg, Ore., has been identified as 26-year-old Chris Harper Mercer, law enforcement sources confirmed to Fox News.
Police have said little about Harper Mercer's background or his motive for the attack.
There is a heavy law enforcement presence outside Harper Mercer's home, and authorities are running his name against terror watch lists, in addition to combing through his email history, phone logs and social media footprint.
According to witnesses, he lined up students in a classroom and asked their religion. Those who answered Christian were shot in the head, while those who answered another religion or did not answer were shot in the legs.
