The 26-year-old shooter who killed nine people at Umpqua Community College in Oregon this week killed himself during a confrontation with police, Sheriff John Hanlin announced Saturday. The BBC reports a medical examiner determined the shooter's cause of death to be suicide. In other developments Saturday, new interviews with survivors and their families cast doubt on whether or not the shooter was specifically targeting Christians, as previously reported. According to the AP, the shooter may have only asked victims if they were "religious," not "Christian." And one official speaking anonymously with the AP says the shooter left a pages-long "manifesto" at the scene of the shooting. He would not reveal what was in the document, and police have yet to identify a motive for the shooting. (More Umpqua Community College stories.)
