Orlando gunman used gay dating app, visited LGBT nightclub on other occasions, witnesses say

The gunman who attacked a Florida LGBT nightclub had attended the club before the attack and had used a gay dating and chat app, witnesses said. Kevin West, a regular at Pulse nightclub, said Omar Mateen messaged him on and off for a year before the shooting using the gay chat and dating app Jack'd. West was dropping off a friend at the club when he noticed Mateen – whom he knew by sight but not by name – crossing the street wearing a dark cap and carrying a black cellphone about 1 a.m., an hour before the shooting. "He walked directly past me. I said, 'Hey,' and he turned and said, 'Hey,'" and nodded his head, West said.
