ST. PETERSBURG, Fla. (AP) — The widow of the gunman who killed 49 people at a gay Orlando nightclub was acquitted Friday on charges of lying to the FBI and helping her husband in the 2016 attack.

Noor Salman, 31, began sobbing with joy when she was found not guilty of charges of obstruction and providing material support to a terrorist organization, WKMG reported . Salman was married to Omar Mateen when he attacked the Pulse nightclub. Police killed him after the massacre.

Prosecutors said Salman and her husband scouted out potential targets together — including Disney World's shopping and entertainment complex — and she knew he was buying ammunition for his AR-15 in preparation for a jihadi attack. She knew that he had a sick fascination with violent jihadi videos and an affinity for Islamic State group websites and gave him a "green light to commit terrorism," prosecutors said.

Defense attorneys described Salman as an easily manipulated woman with a low IQ. They said Salman, who was born in California to Palestinian parents, was abused by her husband, who cheated on her with other women and concealed much of his life from her.

Attorney Charles Swift argued there was no way Salman knew that Mateen would attack the Pulse nightclub because even he didn't know he would attack it until moments before the shooting. His intended target was the Disney Springs complex, prosecutors said.
