He was a body builder and a security guard, a religious man who attended the local mosque and wanted to become a police officer.

Early Sunday, police say 29-year-old Omar Mateen opened fire at a gay nightclub in Orlando in an attack that left 50 people dead and 53 wounded.

Mateen was the son of an Afghan immigrant who had a talk show in the United States, the nature of which was not entirely clear.

He attended evening prayer services at the city's Islamic Center three to four times a week, most recently with his young son, said Imam Syed Shafeeq Rahman. Although he was not very social, he also showed no signs of violence, Rahman said. He said he last saw Mateen on Friday.

He was also bipolar, Mateen's ex-wife, Sitora Yusufiy, told reporters in Boulder, Colorado.
