From the Business Insider:
The man police say killed 49 people at a gay nightclub in Orlando early Sunday morning had visited the club at least a dozen times before carrying out his attack, a witness told the Orlando Sentinel on Monday.
The suspected shooter, 29-year-old Omar Mateen, may have also used several different gay dating apps, according to reports from MSNBC and the Los Angeles Times.
And a former classmate of Mateen's told The Palm Beach Post he believed Mateen was gay, and that Mateen once asked him out romantically.
Three additional witnesses confirmed that they had seen Mateen at the gay nightclub more than once before.
"Sometimes he would go over in the corner and sit and drink by himself, and other times he would get so drunk he was loud and belligerent," one witness, Ty Smith, told the Sentinel.
"We didn't really talk to him a lot," he added. "But I remember him saying things about his dad at times. He told us he had a wife and child." Chris Callen, who performs at Pulse under the name Kristina McLaughlin, told The Canadian Press and CNN's Anderson Cooper that Mateen had been going to the bar one or twice a month "for at least three years."
Smith later told The Canadian Press that Mateen said that he "couldn't drink when he was at home—around his wife, or family.
His father was really strict." Smith and Callen say that they stopped talking to Mateen when he pulled a knife on them after they made a religious comment.
"He said if he ever messed with him again, you know how it'll turn out," Callen said.
