Noor Zahi Salman is the wife of Omar Mateen.

She is 30 years old. She is a mother. She was raised in northern California, where a resident of her childhood neighborhood told The Associated Press that she was "beautiful" and "very nice."

Salman is now the subject of scrutiny after her husband's attack on a nightclub in Orlando, which left 49 people dead before Mateen was killed by police.

Salman has not been arrested, and she has not made any public statements.

In the wake of Sunday's early morning shooting at the gay club Pulse, though, investigators are taking a closer look at members of Mateen's family as they try to understand the 29-year-old gunman and his attack.

Salman has told the FBI that she accompanied her husband to Pulse at least once prior to the massacre, in a trip that a U.S. law enforcement official described as "reconnaissance."

"With respect to the wife, I can tell you that that is only one of many interviews we have done and will continue to do," Ronald Hopper, FBI assistant special agent in charge, said at a Wednesday news conference.

Salman grew up in Rodeo, California, a community about 25 miles northeast of San Francisco, in a family with Palestinian roots, the AP reported.

Neighbors of her family in California told The Washington Post that she did not live in the home and had married Mateen a few years earlier. Salman was described as friendly, outgoing and stylish.

Her father died in 2015, and that was the last time the neighbors saw her.

"You know, some kids after high school, they open up the box and the world is theirs. She was inside the box, just pack it up and get married," a neighbor, Jasbinder Chahal, told AP.

Chahal told the wire service that Salman and Mateen had a small wedding and "took lots of pictures here at the house." She described a sheltered childhood for Salman and her sisters, saying, "Noor never played in the street, and the girls were never allowed to drive."

Other neighbors who spoke with The Post, however, recalled her playing softball and described her family as modern Muslims.

Both Salman and Mateen had previously been married. Mateen's ex-wife has described him as abusive and unstable.
