Shooter ‘mentally unstable, but not a religious extremist': Ex-wife

People close to a gunman who killed 50 people at a gay nightclub in Florida have painted a picture of a violent and prejudiced young man.
Omar Mateen, 29, was a Muslim American of Afghan descent and police are investigating whether he had ties to, or was inspired by, religiously motivated extremism, after a source linked to the Islamic State (IS) group claimed the attack.
The FBI said Mateen apparently made an emergency call just before the massacre to claim allegiance to IS.
Sunday's attack was carried out at Orlando's Pulse nightclub, a well-known gay venue.
But relatives interviewed by US media said Mateen, who worked as a security officer and had a wife and young son, was not especially religious.
They did, however, describe a man who had anti-gay views, mental health problems and was physically abusive to his ex-wife.
Mateen's father, Mir Seddique, said his son had recently been offended to see two gay men expressing affection on a Miami street.
"We were in downtown Miami, Bayside, people were playing music," the shocked father told NBC News in the immediate aftermath of the shooting.
"And he saw two men kissing each other in front of his wife and kid and he got very angry," Seddique said.
The father is a minor celebrity in Afghan political circles, hosting an occasional television show in which he expressed hardline views.
In the "Durand Jirga Show," available on YouTube, he rails against the Pakistani government and announced a quixotic bid to seek the Afghan presidency.
"We are in shock like the whole country," Seddique added. "This had nothing to do with religion."
'Mentally ill'
Mateen's ex-wife said he was violent and mentally unstable - but not a religious extremist.
"A few months after we were married I saw his instability, and I saw that he was bipolar and he would get mad out of nowhere," Sitora Yusufiy told reporters outside her home in Boulder, Colorado.
"After a few months he started abusing me physically ... not allowing me to speak to my family, keeping me hostage from them."
Yusufiy, who met Mateen online and married him in 2009, said he was a practising Muslim but showed no signs of radicalisation.
"There was no sign of any of this at all," she said.
She noted that Mateen was "mentally unstable and mentally ill" and had a history of steroid use.
Steroids can cause mental problems including paranoia and delusional thoughts.
When they split, "my family literally rescued me... they had to pull me out of his arms and find an emergency flight."
The pair were divorced in 2011, according to a court document seen by AFP, and Yusufiy said she has not had contact with Mateen in years.
Regular at mosque
The imam of the mosque where Mateen worshipped said he came to evening prayers three or four times a week, bringing his son who is about four or five years old.
"He would pray and his son would play," said Syed Shafeeq Rahman of the Islamic Center of Fort Pierce, who has known Mateen since 2003 when he became the imam.
Mateen did not socialise, leaving when services ended.
He didn't talk but would smile and shake hands, Rahman told AFP.
"I never expected this," Rahman said, holding a Quran in his hand as he spoke with reporters. "We teach peace and justice."
"It must be some kind of psychological problem or anger problem," the imam said, adding that Mateen might have been radicalised on the Internet.
Bedar Bakht, who knew Mateen as a boy, said he saw him less than a week ago at the mosque with his young son, and that he seemed sad and was very quiet.
Mateen liked to talk about religion and could be intimidating when he argued, he said.
"He was very direct and really into bodybuilding," Bakht said. "He was huge at one point.
"He would tell you if he didn't agree with you," he said. "He may have had some anger issues."
But Bakht said he never saw Mateen speak with hatred of any other group.
"He was respectful," he said. "I never heard him insulting women or gays."
Mateen owned a small calibre handgun and worked as a guard at a secure facility for juvenile delinquents.
Authorities said he bought a handgun and a long gun two days before the attack.
According to the Florida Department of Agriculture and Consumer Services website, he had a gun licence set to expire in September 2017.
