Orlando Gunman Used Multiple Gay Apps to "Hook Up", Say Reports

Orlando: The gunman who massacred 50 people at the Pulse club in Orlando was himself a regular at the gay nightspot, four clubgoers have said.

"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," Ty Smith told the Orlando Sentinel on Monday, referring to slain shooter Omar Mateen.

Smith told the paper that he saw Mateen inside at least a dozen times. "We didn't really talk to him a lot, but I remember him saying things about his dad at times," Smith said. "He told us he had a wife and child."

Another Pulse regular, Kevin West, told the Los Angeles Times that Mateen messaged him on and off for a year using a gay chat app.

And other clubgoers said that Mateen had been using multiple gay apps, including Grindr, with mutual acquaintances to "hook up."

Mateen also was at Walt Disney World in April, said a Disney manager who requested anonymity.

His wife, Noor Zahi Salman, was not cooperating with authorities, according to a law enforcement official who spoke on the condition of anonymity, the Sentinel said.

Fifty people were killed and 53 others wounded in the attack, which was also the deadliest mass shooting in US history.

FBI chief James Comey said his bureau was "highly confident" Mateen had been "radicalised" while consuming online propaganda and that he had claimed allegiance to Islamic State leader Abu Bakr al-Baghdadi in a series of calls during the attack.
