The two wed in Florida, but the marriage only lasted a few months, and the woman now resides in Colorado.
The gunman in a mass shooting that left at least 50 people dead and 53 others wounded early Sunday in an Orlando night club was once married to a former New Jersey woman.
Omar Mateen is the suspected shooter in an attack that left 50 people dead in Orlando, June 12, 2016. Records show Omar Mateen, who died in a shootout with a police, married Sitora Yusufiy in 2009 in Florida.
Yusufiy told the Washington Post that Mateen was mentally unstable and beat her during their brief, months-long marriage. The two met online.
Yusufiy lived in Edison and Lawrenceville before moving to Florida with Mateen.
Public records show she was registered to vote at an address on Winthrop Road in Edison as recently as 2014.
Edison police officers and FBI agents were present at the home on Sunday afternoon, as representatives of the news media gathered outside the 2-story house. According to Edison police, the FBI had been in the house.
An FBI public information officer said the agency would not comment on the ongoing investigation.
Neighbors on Winthrop Road said they did not know the residents of the home, and could not confirm whether they were relatives of Yusufiy.
Mateen and Yusufiy formally divorced in 2011, according to Florida court records.
According to media reports, her parents intervened when they learned Mateen had beat her.
Yusufiy told Heavy.com her parents "literally saved my life" when they took her away from Mateen.
Her father, who asked not to be identified, told The New York Post that within months of marrying Mateen, Yusufiy called and asked her parents to help get her out of the relationship.
"She was suffering physical and mental abuse from him. The cops were called on him," he said.
Yusufiy has since moved to Colorado, where she works as a creative marketing director for Rainforest Awareness Worldwide, according to her LinkedIn page. She is engaged to the founder and owner of the business. The site also says she studied psychology at Montclair State University.
She received a license to work as a home health aide in New Jersey in 2008, according to state records.
Mateen is suspected of using an assault-type rifle and handgun in a crowded gay nightclub, killing at least 50 people before being killed by police. The mass shooting was the deadliest in American history.
Authorities are investigating the attack as an act of terrorism. Mateen's father said his son recently became angry when he saw two men kissing in Miami, which may have prompted the attack.
Mateen reportedly called 911 shortly before the attack and pledged allegiance to the Islamic State, CNN reported.
The death toll is likely to climb with 53 people hospitalized, most in critical condition, a surgeon at Orlando Regional Medical Center said to the Associated Press.
