Sitora Yusufiy, Omar Mateen's first wife, described how he 'seemed like a normal human being' at first. The two met online and married in 2009 after a brief romance.
Omar Mateen transformed from a friendly high school football player to a quiet father who carried out America's deadliest mass shooting, leaving old friends and family members in shock.
Mateen, who worked as a security guard, walked into a gay nightclub in Orlando, Florida, with a handgun and AR-15 semi-automatic rifle, killing 50 people on Sunday before police stormed the club and fatally shot him.
A gay, high school classmate who knew Mateen before 2009 said the 29-year-old regularly interacted with him and his other gay co-workers and 'treated us all like the individuals we were.'
But the terrorist's father said his son had recently become infuriated at the sight of two men kissing, while others said he was an 'agitated' and 'aggressive' bodybuilder.
Mateen's first wife claimed he was mentally ill and physically abusive, while a coworker said: 'He talked about killing people all the time. I wasn't shocked. I saw it coming.'
He had worked for G4S since 2007, the world's largest security company, which provides guards for US nuclear facilities.

Mateen went on to earn an associate's degree in criminal justice from Indian River State College in Fort Pierce, and expressed interest in joining the police force.
Instead, he worked as a security officer, a fact that comforted other members of the Islamic Center of Fort Pierce where he worshipped, Syed Shafeeq Rahman, the head of he mosque, said.
'He hardly had any friends. He would come with his little son at night to pray and after he would leave.'
Rahman told the NY Times: 'There is nothing that he is hearing from me to do killing, to do bloodshed, to do anything, because we never talk like that.'

The Islamic center also released a statement condemning the 'monstrous' attack that read: 'The Muslim community of Fort Pierce joins our fellow Americans in repudiating anyone or any group that would claim to justify or excuse such an appalling act of violence.'
The terrorist's father Seddique Mir Mateen also denied that the attack had anything to do with religion, and said his son had become enraged after seeing two men kissing in Miami months before.
While the father said he was 'in shock like the whole country,' the terrorist's former coworker, Daniel Gilroy, told the Times: 'He talked about killing people all the time.'
Gilroy said he made several complaints to G4S, the company where they both worked, because Mateen frequently used racial, ethnic and sexual slurs and sent him a barrage of 20 to 30 text message a day.
'He was always shaken, always agitated and always mad,' Gilroy added.

After spending most of the day searching Omar Mateen’s Port St. Lucie home, cops and the FBI moved on to the custom-built four-bedroom home a couple of blocks of north on Bayshore Boulevard where his parents live.
Neighbor, Tony Schneider, a retired deputy sheriff told Daily Mail Online that Seddique and Shahla Mateen are ‘the nicest people in the world.’
‘They are very Americanized, he said. ‘Just very good neighbors. I have known them for six years and have never had any problems with them.
