"I was pretty angry. I was anxious all week not knowing if he was going to cross-examine my husband or not, and not sure how my husband will deal with that," she said. "I noticed he was making eye contact with my husband, and that just infuriated me."
Inside the courtroom, shortly before the verdict was delivered, the judge cautioned the spectators in the gallery against outbursts.
Hasan stroked his beard as the jury -- a military panel of 13 senior officers -- filed into the courtroom. He then looked at the head of the jury -- a colonel -- who affirmed a verdict had been reached.
Hasan showed no emotion as the verdict was read, a contrast to a handful of some of family members who cried or gave one another brief hugs.
'A first, small step down the path of justice'
"Today's guilty verdict, rendered almost four years after the attack, is only a first, small step down the path of justice for the victims," said attorney Neal M. Sher, who represents victims and families of those killed in a compensation claim against the government for failing to stop the attack.
Almost immediately after the attacks, there were widespread questions about how Hasan was evaluated, promoted and transferred to Fort Hood with plans to deploy to Afghanistan despite questions about his actions, including giving an academic presentation on the value of suicide bombings.
Sher renewed the call for the government to reclassify the shootings as a "terror attack" rather than workplace violence.
"Justice for the victims of Fort Hood will be done only when the government admits its mistakes, keeps its promises to 'make the victims whole' and comes clean about Fort Hood, " Sher said. " The victims, and the American people, are owed nothing less."
As has been done nearly every day in the three-week court-martial, the judge asked Hasan if he had reconsidered defending himself as the case enters the penalty phase.
Jurors "will decide whether you live or die," the judge, Col. Tara Osborn, told Hasan after reconvening the court Monday afternoon as part of the penalty phase preparation. "...I think it is unwise for you to represent yourself."
Hasan told the judge he intended to continue representing himself in the case.
'Jihad duty to kill'
On Thursday afternoon, the judge handed the case to the jury after Hasan declined to make a statement during closing arguments that followed 12 days of testimony.
The prosecution urged the jury to convict, saying the evidence showed that Hasan believed he had a jihad duty to kill as many soldiers as possible.
For more than 90 minutes, the prosecutor took the jury methodically through the evidence in the case, meticulously piecing together how he said Hasan prepared and planned for the attack.
Prosecutors have maintained that the American-born Muslim underwent a progressive radicalization that led to the massacre at the sprawling central Texas base.
"He did not want to deploy, and he came to believe he had a jihad duty to kill as many soldiers as possible," Col. Steven Henricks told the jury.
Hasan picked the day -- November 5, 2009 -- because it was when the units he was scheduled to deploy with to Afghanistan were scheduled to go through the processing center, he said.
Hasan rested his case without calling a single witness or taking the stand to testify on his own behalf.
His decision not to offer a defense was an anticlimactic end to the trial in which prosecution witnesses, primarily survivors, painted a horrific picture of what unfolded inside a processing center during the attack.
During closing arguments, prosecutors showed a graphic FBI video of the crime scene hours after the rampage, where bodies, blood and bullets still covered the floor.
As the video was shown to the jury, some of the family members of those killed fought back tears.
One woman laid her head on her husband's shoulder, tears streaming down her cheeks, while another woman, a wife of a victim, left the courtroom.
For his part, Hasan watched the video, appearing to pay close attention
