According to The Associated Press, the mother of the 26-year-old Oregon gunman who killed nine and injured nine "told investigators he was struggling with some mental health issues." Yes, he was.

It's a profile so familiar it's cliche. Dylann Roof, the "quiet" 21-year-old white supremacist accused of murdering nine people in a Charleston, South Carolina, church in June, was similarly disturbed.
