Shooter frequented gay club and used gay dating app, witnesses say-Los Angeles Times
The gunman who carried out Sunday's massacre at a gay nightclub in Orlando had been a customer there many times and used a gay dating and chat app, according to people who frequented the club.
Kevin West, a regular at Pulse, said Omar Mateen messaged him sporadically over the last year using the app Jack’d.
...
West was dropping off a friend at the club when he noticed Mateen crossing the street wearing a dark cap and carrying a cellphone at about 1 a.m., an hour before the shooting.
...
At least four regular customers of Pulse told the Orlando Sentinel on Monday that they believe they had seen Mateen there before.
[Ty Smith, aka Aries] saw Mateen at the club at least a dozen times, he said.
