A Florida woman said the gunman in the massacre at a gay Florida nightclub stalked her nearly a decade ago when he started coming into the bar where she worked.

Heather LaSalla of Fort Pierce, Fla., told the Associated Press that Omar Mateen sent her so many uncomfortable messages on Facebook that she blocked him.

She ran into him again at a park in November while she was with her young son and Mateen was with his, she said. He talked about his sonโ€™s soccer league, but he still had a weird vibe about him, she said.

Early Sunday, the 29-year-old Mateen opened fire at the Pulse club in Orlando, leaving 49 victims dead and 53 wounded, according to police.

LaSalla said that when she saw his picture on television after the massacre, she knew right away it was him.

She was a bartender in Port St. Lucie at the time and says she never filed a criminal complaint over his behavior.
