Amid reports that the gunman who on Sunday killed 49 people at a gay nightclub in Orlando used gay hook-up apps, his ex-wife said Wednesday that she questioned his sexuality.

Police shot and killed Omar Mateen, the 29-year-old who opened fire early Sunday morning in Pulse nightclub.

Sitora Yusufiy has previously accused her ex-husband of beating her on a regular basis.

On Wednesday, she told CNN's Don Lemon that she questioned Mateen's sexuality.

“To me personally, with everything that I went through and everything that I saw and experienced daily, it makes sense, because he did have a different side of him that he could not open up to his father about,” Yusufiy said.

“So, do you think that he had gay tendencies?” Lemon asked.

“I am not going to lie. I definitely questioned it in my own head when I was with him and wondered if he is, 'cause he would do a lot of things … that would definitely make any woman question if he was or not,” she added.

Those things, according to Yusufiy, were Mateen's love for taking selfies and going to nightclubs.
