I believe the club goers that saw Omar in Pulse several times, probably casing the joint. On the gay apps? possibly, but we know how people can create sock puppet accounts and or use other peoples photos as their own. This man and "ex lover" in disguise? probably not, not sure why someone would do this just to deflect internal blame on the gay community, hmmmm
FBI investigators say they have found no evidence that Orlando shooter had gay lovers http://www.latimes.com/nation/la-na-orlando-gay-fbi-20160623-snap-story,amp.html
Since the shooting at an Orlando nightclub last week that left 49 people dead, reports have emerged that gunman Omar Mateen frequented the gay club, used gay dating apps and had gay lovers.
But the FBI has found no evidence so far to support claims by those who say Mateen had gay lovers or communicated on gay dating apps, several law enforcement officials said
Several Pulse regulars have come forward in the days since the shooting, claiming to have seen Mateen at the club or to have been contacted by him on the gay dating apps Grindr, Jack’d and Adam4Adam.
On Tuesday, Univision aired a report in which “Miguel,” a man wearing a disguise to conceal his identity, alleged he had sex with Mateen after meeting him on the gay dating app, Grindr. He said Mateen had sex with other men too, including a threesome with a Puerto Rican who allegedly told Mateen, after having had unprotected sex with him, that he was HIV positive.
But investigators do not consider the man’s account credible, according to one senior law enforcement official with access to the investigation.
So far, they have found no photographs, no text messages, no smartphone apps, no gay pornography and no cell-tower location data to suggest that Mateen — who was twice married to women and had a young son — conducted a secret gay life, the officials said.
