The gunman who killed nine people at an Oregon community college said in writings he left behind that everyone else was "crazy" and ranted about not having a girlfriend, a law enforcement official says. The official—who is familiar with the ongoing investigation but wasn't authorized to speak publicly—also says the mother of 26-year-old gunman Christopher Harper-Mercer has told investigators he was struggling with some mental health issues. Harper-Mercer complained in writings about not having a girlfriend, and he seemed to feel like he was very rational while others around him were not, the official says. He wrote something to the effect of: "Other people think I'm crazy, but I'm not. I'm the sane one," the official says. The writings were a couple of pages long.
On Monday, some faculty, staff, and students returned to the campus for the first time since the shooting. Classes do not resume at Umpqua Community College until next week, but some students came to the campus to pick up belongings they left behind Thursday when they fled. Others met with professional groups to discuss their trauma and grief. "I'm going through the grieving process myself because this has touched everyone in the community," a chaplain tells the AP. "If you don't know someone [who] goes here, you know someone [who] knows someone." President Obama plans to visit Roseburg on Friday to meet privately with victims' families. (Harper-Mercer's mother boasted online about her guns.)
