Oregon shooter had ‘some mental health issues’

The British-born gunman who murdered nine people at an Oregon community college before killing himself ranted about not having a girlfriend and thinking everyone else was “crazy”, a source close to the investigation has said.

The law enforcement source, who is familiar with the case, also said the mother of Christopher Harper-Mercer, 26, told investigators he was struggling with some mental health issues.

Harper-Mercer complained in a manifesto he left behind about not having a girlfriend and seemed to feel like he was very rational while others around him were not, the official said.
