CNN aired an interview with Orlando shooter Omar Mateen’s ex-wife Sitora Yusufiy Sunday.

Yusufiy told reporters that Mateen had a history of steroids, which she suspected had something to do with his “unstable” state of mind.

“[Omar Mateen] was mentally unstable and mentally ill. That’s the only explanation that i could give and he was obviously disturbed, deeply and traumatized,” Yusufiy said. “I know that he had a history of steroids. I don’t know if that caused it. I’m sure it had something to do with it, you know?”
