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.

COLLEAGUES COMPLAINED ABOUT MATEEN'S 'FREQUENT' RACIST AND HOMOPHOBIC COMMENTS AND SAID HE WAS 'UNHINGED'
Mateen led what many would consider a normal life: he was married, had a child and worked as a security guard.
But he was really an 'unhinged' extremist who regularly made homophobic and racist remarks at work.
That's the account of former police officer Daniel Gilroy who worked alongside Mateen, 29, for security firm G4S.
Gilroy said he complained to bosses but they did nothing because of Mateen's Muslim faith.
'I quit because everything he said was toxic,' Gilroy told Florida Today.
'...and the company wouldn't do anything. This guy was unhinged and unstable. He talked of killing people.'
Gilroy said Mateen would take over from him on shift at PGA Village between 2014-15.
Mateen began stalking him, sent up to 30 messages and made around 15 calls to him a day, Gilroy added.
Mateen was connected to two homes in Port St Lucie, Florida - at 519 SW Bayshore Boulevard and 937 SW Bayshore Boulervard

Mateen had a son with Noor Zahi Salman, and the two lived at the same St Lucie County address in 2012, according to records seen by DailyMail.com.
Salman was listed as his wife on a September 2013 mortgage filed in the county, according to Buzzfeed, after Mateen divorced his first wife, Sitora Yusufiy, in 2011.
But it is unclear whether Mateen and Salman are still together, since she has been living at a different address.
Born in New York to Afghan parents, Mateen and his family moved to Florida when he was a child.
He graduated from Martin County High School in 2004 and 'got really buff' while he worked at the nutrition store GNC at a local mall, according to his classmate Samuel King, who was a year older.
King said: 'What is shocking to me is that the majority of the staff at Ruby Tuesday's when I worked there were gay.
'He clearly was not anti-[gay], at least not back then. He did not show any hatred to any of us. He treated us all like the individuals we were. He always smiled and said hello.'
King, who characterized Mateen as friendly and talkative, said: 'Something must have changed.'

MATEEN WAS 'DISTRESSED' WHEN HE BOUGHT ST LUCIE PROPERTY IN 2013
Further details about Mateen's property arrangements have come to light.
Police officers have removed evidence from 519 and 937 south-west Bayshore Boulevard, St Lucie.
The four and three-bed homes are a four minute drive between each other.
Mateen was said to be in a 'distressed' state when he bought number 937 for $95,000 in September 2013. Today it is thought to be worth about $190,000.
The Palm Beach Post reported that he took out a $76,000 loan to finance the home. It was advertised as a 'spacious pool home' which needs 'a little TLC'.
The second home at 519 was bought for $160,000 in 2010, having been built two years earlier.
His father Mir Seddique, also known as Seddique Mateen, has his company The Durand Jirga, registered at 519.
It has 10 rooms and is built over two stories and is worth about $250,000.
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.

Sitora Yusufiy, Omar Mateen's first wife, described how he 'seemed like a normal human being' at first.
Following a brief romance after the two met online, the pair married in 2009 and moved into a two-bedroom home owned by Mateen’s family in Fort Pierce.
‘After a few months he started to beat me,’ she said. ‘He was mentally unstable… he was obviously disturbed. I know he had a history of [taking] steroids.
'He was not a stable person. He would just come home and start beating me up because the laundry wasn’t finished or something like that.'
Yusufiy said that Mateen owned a gun during their marriage, was ‘short tempered’ and would express ‘hate towards things’. She would not reveal if he had any homophobic views.
Her parents eventually intervened and the two separated, although their divorce wasn't finalized until 2011.
People around the country have gathered, mourning the 50 people who have been killed in the deadliest mass shooting in American history. Pictured, a candlelight memorial in Seattle on Sunday

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.
Mateen had been living in a condo rental apartment in Fort Pierce for the past nine months. Investigators sealed off the apartment and brought in bomb testing equipment.

‘My heart goes out to them — of course if they were involved they can rot in hell, but I otherwise I feel so sorry for them.’
Schneider said that Seddique — who he knows as Sid — can often be seen in his yard and walking up and down the street. He said he did not know his wife nearly as well.
‘I believe he is in insurance, he has done well for himself and they have three daughters, all went to college, who I believe are in the medical field.
‘But I didn’t know the son. I saw his picture on television this morning and I recognized him, but he only came here rarely.’
Mateen had moved out of the family home nine months ago around the same time he 'wuick deeded' the apartment to a man believed to be a family friend for $100.
