ROSEBURG, Ore. — A law enforcement official says the gunman who killed nine people in an Oregon classroom last week ranted about not having a girlfriend in a manifesto left behind for authorities.
The official is familiar with the investigation but not authorized to speak publically and commented on condition of anonymity. The official says that in the multi-page document recovered last week, Christopher Harper-Mercer also complained that others around him thought he was crazy.
The official says the gunman wrote he was sane and others were unbalanced.
Harper-Mercer opened fire at Umpqua Community College in Roseburg, killing nine. He committed suicide as officers arrived on the scene.
