Psychotic

On the morning before the massacre at Orlando’s Pulse gay nightclub, shooter Omar Mateen drastically altered his appearance, shaving his head and face, and seemed agitated and surly, said an acquaintance who saw him that day.

Mateen also talked about staying up all night to do online research into anti-psychosis medication, the acquaintance said in a interview. The acquaintance requested anonymity, saying authorities had asked him to keep quiet.

Dude, I think they're going to know it was you.

The FBI would not comment on the acquaintance’s remarks, but several senior U.S. sources told Reuters the investigation was moving more toward the belief that Mateen's motives were personal rather than political.

Too late. We've already labeled him. And we have legislation we want to enact.
