Oregon gunman complained others thought he was crazy

President Barack Obama will travel to Oregon this week to visit privately with families of the victims of last week’s shooting at a community college.

Obama will visit Roseburg on Friday as he opens a four-day trip to the West Coast.

No additional details about his visit were immediately available.

Obama has renewed his call for stricter gun laws following the shooting and has expressed exasperation at the frequency of mass shootings in the U.S.

Nine people were killed when a 26-year-old opened fire in a classroom at Umpqua Community College before killing himself in a shootout with police.

Another nine people were wounded.

Some faculty, staff and students have been bringing flowers to a makeshift memorial as they return to the campus for the first time since the shooting.

A law enforcement official says the gunman ranted about not having a girlfriend in writings he 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 writings 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 killed himself as officers arrived at the scene.
