Federal prosecutors and defense attorneys for Noor Salman made their final cases to a 12-member jury in an Orlando courtroom, and the case is now in the jury's hands.

Closing arguments began Wednesday in the trial of Salman, the widow of the Pulse nightclub shooter who's charged with aiding and abetting her husband, Omar Mateen, in the June 2016 massacre, one of the deadliest in modern U.S. history.

Assistant U.S. Attorney Sara Sweeney argued that Salman knew what Mateen was planning to do.

"She knew the attack was close," Sweeney told the 12 jurors. "She saw these things as a green light."

Mateen opened fire in the crowded nightclub in June 2016, killing 49 people and leaving 53 others wounded.

Sweeney argued that Salman knew an attack was coming but may have been confused about the location of Pulse. She said Salman may have thought the nightclub, which is south of downtown Orlando, was in or around Disney Springs.

"The target of that terrorist attack was not the Pulse nightclub," Sweeney said. "The target of the attack was Disney."

Sweeney showed a video of the Disney Springs complex that captured Mateen walking near the House of Blues club in the hours before the Pulse attack. In it, he looks behind him at police officers standing nearby.

Prosecutors also told jurors about how Mateen planned to a use a baby stroller to hide his assault rifle until he got inside House of Blues.

Regardless of whether Salman knew which one was the target, prosecutors said it didn't matter.

"We do not have to prove Noor Salman herself is a supporter of ISIS (the terror organization). Only that she supported her husband’s attack," Sweeney told jurors.

Federal prosecutors say that Salman herself admitted to knowing specific details of Mateen's plans, which the FBI investigated and later confirmed were true. They said it's proof that Salman wasn't coerced but knowingly told the FBI she was part of the plans her husband made.

Defense's closing arguments

Attorney Linda Moreno described Salman as being a sweet and shy woman who struggled educationally. She had no strong political views nor idealogy of radicalization, defense attorneys said.

Moreno says prosecutors can't prove their case – and are now changing their theory, no longer sticking to accounts of Noor Salman and Omar Mateen scoping out Pulse nightclub in the days before the attack.

Salman never cased Pulse like FBI agents described, they said, adding that Mateen randomly picked Pulse as a target.

“If he didn’t know where he was going, how could Noor know where he was going?” Moreno said.

Defense attorneys painted Salman as someone easily manipulated and coerced, with details of the aftermath planted in her head by FBI agents.

"(It was a) horrible, random, senseless killing by a monster, but it wasn’t preplanned, and if he (Mateen) didn’t know, she (Salman) can’t know," defense attorney Charlie Swift told jurors.

Outside the courthouse

Emotions were also were running high outside the federal courthouse in downtown Orlando.

Christine Leinonen, the mother of Pulse nightclub victim Christopher Andrew Leinonen, said she was hoping to learn more about her son’s death, but “I didn’t get some of the answers that I thought,” she said.

She said she hopes for a guilty verdict.

“I believe that she full well knew that jihad was imminent and she helped him,” Leinonen said of Salman.

Salman family members who have been present for each day of the trial disagreed.

“What the prosecutor said, it’s all theory," said Salman's uncle, Al Salman. "I don’t know how they imagine a thing.”

Al Salman said he agreed with how the defense described his niece: a woman who misses her son back in California who is ready to put the trial behind her.

“That’s the Noor we know," he said. "What she told us about it exactly, that what it is.”

Susan Clary, a Salman family spokesperson, remained optimistic.

“We’re very hopeful that the jury will now hunker down and do their job and find her not guilty," she said.

Salman's uncle is confident that will happen.

“I feel she should be free. She’s innocent,” he said.

Leinonen said if Salman is convicted, she plans to give an impact statement in court.
