>> New details emerging on the man who carried out the deadliest shooting in recent US history. Shooter Omar Mateen drastically altered his appearance, shaving his head and face, and seemed agitated and surly, according to an acquaintance who saw him on June 12th, the day Mateen attacked a gay night club in Orlando killing 49 people.
Reuters correspondent Bernie Woodall is on the story.>> In the last several days, Reuters learned that an acquaintance of the Orlando shooter who knew him as a resident of PGA Village, the gated community where Mr. Mateen was one of the security guards. About 3 or 4 weeks before the shootings, Omar Mateen began acting more curious.
When the acquaintance asked the guard how you doing, Mateen would say I'm not doing so well, I've been staying up all night looking online for these research in these antipsychotic drugs. And apparently, he was afraid that if he didn't medicate himself somehow, he would slip into psychosis. That's what his words were according to the acquaintance.
>> The 29-year-old gunman pledged allegiance to the Islamic State before being fatally shot by police after a three hour siege. The FBI would not comment on the acquaintances' remarks, but Reuters has learned that the Orlando investigation is moving toward the idea that Mateen's motives were personal rather than political.
Official sources say this may have been the act of a seriously troubled individual. Whose personal problems dwarfed any last-minute inspirations from radical groups.
