Several witnesses have come forward saying they frequently spotted Mateen in gay bars and on a gay messaging app, while his former wife Sitora Yusufiy had told Brazilian television that he had “gay tendencies”.
Speaking to SBT Brazil on Monday, with her fiancé Marco Dias translating in Portuguese on her behalf, she also said Mateen’s father called him gay in front of her.
She claims she was told by the FBI not to tell this information to the US media.
The revelations come amid allegations that Mateen was a regular at Pulse nightclub, the scene of the massacre, and had asked out one former classmate on a date.
Speaking to the Palm Beach Post, the unidentified man who attended a police academy with Mateen said he believed he was gay, but not open about it.
