Widow of Pulse nightclub shooter knew of attack, FBI agent says

The widow of Pulse mass shooter Omar Mateen declined to testify in court Friday during an evidence suppression hearing.

Lawyers for Noor Salman, who is accused of aiding Mateen in planning and carrying out the June 12, 2016 attack that killed 49 people and injured at least 68 more, argued that statements she made to the FBI the day of the attack -- that indicate she was aware of her husband's plans -- should not be allowed into evidence during her trial.

FBI agents note that statements she made after the attack reveal she knew more than she initially let on.

Here are the key details revealed during this week's court proceedings.

Salman told the FBI her husband had been visiting extremist websites

FBI Special Agent Ricardo Enriquez, who interviewed Salman the day of the attack, said she told him that Mateen had been exploring extremist websites for about two years before the attack. But she claimed in their first interview not to know that he was planning an attack, Enriquez said in court, according to The Orlando Sentinel reported.

Salman said she was "sorry for what happened," wished she had warned police of attack

After his initial interview with her, Enriquez asked Salman to write a paragraph and say that nobody was forcing her to be there.

At the end of her statement she wrote, "I am sorry for what happened. I wish I could go back and tell his family and the police what he was going to do."

Enriquez said that's when he realized "that she knew."

Salman later told the FBI she and her husband had driven around Pulse nightclub

In another statement, Salman told Enriquez that after she visited Disney Springs with her husband, they drove around the site of the attack for about 20 minutes, with the car's windows down.

Salman's lawyers suggested that the couple hadn't actually been in the area together.

"It would shock you if it wasn't true," Salman's defense attorney, Swift asked Enriquez. "It would shock you if the GPS said they never went near the Pulse nightclub?"

Enqriquez said he had simply recorded Salman's statement to him.

Salman said she saw her husband researching the club online

Enriquez said Salman saw her husband looking at a photo of the club on June 10, 2016-two days before the attack.

Mateen told her that Pulse was his target, Enriquez said. He said that's when Salman realized the attack was imminent.

Salman knew Mateen was dead, even though no one had told her that

Christopher Mayo, the first FBI agent to interview Salman after the attack, said that she indictated she knew her husband was dead, even though she hadn't yet been informed of his death, ABC-affiliate WFTV9 reported.

Salman made reference to Mateen's attitude toward homosexuals

Salman claimed her husband would never hurt anyone because he liked everyone, including homosexuals, Mayo said. But Mayo notes that she shouldn't at that point have known that the attack had been made on a popular gay club in Orlando.

The couple spent more than $25,000 leading up to the attack

Thursday's motion said Salman knew Mateen was planning an attack based on his spending habits leading up to the massacre.

Financial records show the pair made more than $25,000 in credit card purchases and withdrew more than $5,500 in cash in the weeks leading up to the attack.

Tax filings show the couple only earned about $30,000 annually.
