The carnage inside an Orlando gay nightclub had been raging for 20 minutes when Omar Mateen called 911.
In the call, Mateen pledged allegiance to ISIS leader Abu Bakr al-Baghdadi and mentioned the two men who set off a bomb at the Boston Marathon in 2013, officials said.
What the call did not say, but others did, was that Mateen had been seething with anger at the world around him.
“He was scary in a concerning way,” said Daniel Gilroy, a co-worker at G4S Secure Solutions. “And it wasn’t at times. It was all the time. He had anger management issues. Something would set him off, but the things that would set him off were always women, race or religion. (Those were) his button pushers.”
Mateen “always referred to every other race, religion, gender in a derogatory way,” Gilroy added. “He did not like black people at all. That was mentioned once or twice, but more so was women. He did not like women at all. He did like women in a sexual way, but he did not respect them.”
Mateen was also recently affronted by the behavior of a gay couple, his father said.
“We were in downtown Miami, Bayside, people were playing music. And he saw two men kissing each other in front of his wife and kid, and he got very angry,” Mateen’s father, Seddique Mir Mateen, said Sunday. “They were kissing each other and touching each other, and he said, ‘Look at that. In front of my son, they are doing that.’ And then we were in the men’s bathroom, and men were kissing each other.”
