FORT HOOD, Texas (CNN) -- A military jury on Friday convicted Army Maj. Nidal Hasan of 13 counts of premeditated murder and 32 counts of premeditated attempted murder in a November 5, 2009, shooting rampage at Fort Hood, Texas, making it possible for the death penalty to be considered as a punishment.
The jurors deliberated fewer than seven hours over two days to hand down a verdict against Hasan, who admitted to targeting soldiers he was set to deploy with to Afghanistan to protect the Taliban and its leaders. The shooting rampage occurred at a deployment processing center.
The court-martial next moves to the penalty phase, where Hasan -- acting as his own attorney -- will have the opportunity to address the jurors considering whether he should be executed for his actions.
Deliberating since Thursday afternoon
On Thursday afternoon, a judge handed the case to the jury, a panel of 13 senior officers, after 12 days of testimony.
After nearly three hours of deliberations, the panel asked to rehear the testimony of the police officer who shot Hasan, ending the rampage that left 13 people dead and dozens wounded.
Jurors also asked to see a map marked by the police officer, Mark Todd, indicating where he shot Hasan.
The questions appeared to indicate that the jury was evaluating the charge -- premeditated attempted murder -- against Hasan for firing at Todd, who was not wounded in the attack.
Later, the judge reconvened the court-martial so that the jury could ask two questions about paperwork.
Hasan doesn't call witnesses, give closing argument
The jury began deliberations after Hasan declined to make a statement during closing arguments.
The prosecution urged the jury to convict, saying the evidence showed that he believed he had a jihad duty to kill as many soldiers as possible.
"There is no doubt, as I said in the beginning, the accused is the shooter," the prosecutor, Col. Steven Henricks, told the jury.
"The only question for you is ... is this a premeditated design to kill?"
For more than 90 minutes, the prosecutor took the jury methodically through the evidence in the case, meticulously piecing together how he says 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," 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.
A graphic FBI video during closing arguments
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 pouring 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.
Hasan, who has insisted that the jury not be allowed to consider lesser charges against him, said his attack on soldiers at Fort Hood was not an act of "sudden passion."
There was "adequate provocation" for the attack because the soldiers were going to participate in "an illegal war" in Afghanistan, Hasan told the military judge Wednesday, arguing against the jury being allowed to consider voluntary manslaughter or unpremeditated murder.
Prosecutors argued against the inclusion of lesser charges, saying the attack wasn't carried out in "the heat of sudden passion," and Hasan said he agreed.
The judge ruled that the jurors can consider a lesser charge of unpremeditated murder but not voluntary manslaughter. They can also consider unpremeditated attempted and other lesser charges, she ruled.
Much has been made of Hasan's defense or, as his stand-by attorneys have said, the lack of it. Judge Tara Osborn declined a request by Hasan's attorneys to drop out of the case. The attorneys argued that Hasan was helping the prosecution put him to death.
There may be something to that claim.
Hasan took credit for the shooting rampage at the outset of the trial, telling the jury during opening statements that the evidence will show "I was the shooter."
Osborn barred Hasan from pleading guilty at the start of the court-martial. Under military law, defendants cannot enter guilty pleas in capital punishment cases.
The judge has refused to allow Hasan to argue
