Jury selection began Thursday in the federal trial of Noor Salman, the widow of the man who shot and killed 49 people in a nightclub in 2016

The 31-year-old mother-of-one looked 'very serious and tired,' according to a WESH reporter.

Another reporter from WFTV said Salman wore a black sweater to the hearing, with her hair pulled back.

'She is swaying back and forth in her chair,' the reporter said.

U.S. District Judge Paul G. Byron questioned jurors one by one about their knowledge of the Pulse nightclub shooting and whether they knew anyone connected to the incident or the case, in what will likely be a lengthy jury selection.

They were also asked their feelings on the 9/11 attacks and the recent shooting in Parkland, Florida.

Before taking a break for lunch as 12:30pm, the court had interviewed four jurors - two were put on the jury and two were dismissed.

One of the dismissed jurors is the mother of a seven-week-old baby who lives just blocks from the club and said she didn't know if she could be impartial. The judge dismissed her in part because he feared she would be sleep deprived taking care of her new baby.

Each person called had previously filled out a lengthy questionnaire about their backgrounds, opinions, and knowledge of the case.

The judge said the trial could last five weeks or more once the twelve jurors are chosen.

The jury members will not be sequestered together. Instead, they will meet an an undisclosed location every morning before the trial to be taken covertly to the court. At the end of they day, they will taken back to the undisclosed location and return home from there.

About 15 survivors and victim's family members were in court for the jury selection on Thursday, but were asked to cover up any clothing that might make a statement.

Among those who attended the hearing was Pulse owner Barbara Pomo.

Salman, who is 31, is charged with aiding and abetting her husband, Omar Mateen, in planning the attack. She's also been charged with obstruction of justice and faces life in prison if convicted.

On Thursday morning prior to the proceedings, a man stood across the street from the courthouse holding a sign that read, "'FRY' HER TILL SHE HAS NO 'PULSE.'" There were no other visible demonstrators, but security in the federal courthouse was tight. Some Pulse victims' families are in attendance.

'She deserves the death penalty. Nothing less,' the man, Bob Kunst, told the Orlando Sentinel. 'You have to send a message to every one of these people that are out there ready to do us in that you have to pay the penalty.'

If convicted, Salman faces the possibility of life in prison but not the death penalty.

At the time of the June 16, 2016 massacre, it was the worst mass shooting in the United States. Mateen, who had pledged allegiance to the Islamic State, was killed by police in the hours after the shooting.

Prosecutors say Salman lied to authorities about her knowledge of her husband's plans. She was arrested in California in 2017, where she was staying with family, and has been in jail since.

From various court documents, it is expected that the defense will say Salman was abused and afraid of her husband, and was unable to question him about the attack. Her attorneys also claim she wasn't given proper Miranda warnings by authorities before she made statements.

On Wednesday, the judge unsealed some documents in the case that were submitted by the defense. A nurse and a psychologist who evaluated Salman said she was physically abused by her husband and was afraid to question him about the attack.

'Noor Salman is a severely abused woman who was in realistic fear for her life from her abusive husband,' wrote Jacquelyn Campbell, a nurse whom defense lawyers are offering as an expert in domestic violence and PTSD. 'Her behavior was entirely consistent with severely abused women who are completely controlled by a highly abusive male partner.'
