Jodi Arias could now face the death penalty, nearly five years after she stabbed, shot and almost decapitated her ex-boyfriend.
A jury Wednesday found that Arias was "exceptionally cruel" when she murdered Travis Alexander in 2008. That verdict is a key step that makes Arias, 32, eligible for the death penalty in the next phase of her trial.
Arias sobbed in the courtroom Wednesday as a prosecutor presented evidence.
Around her, the courtroom was silent for two minutes.
That's how long Travis Alexander suffered in pain as Arias attacked him, Prosecutor Juan Martinez said.
"Does that seem like a short period of time? It was an incredibly long period of time to be continually stabbed, to be continually followed," Martinez said.
And Arias, he argued, was well aware of how much Alexander was suffering.
"He was stabbed in the heart, chased down and then he had his throat slit," Martinez said. "Those approximately two minutes that we talked about must have seemed like two lifetimes."
Alexander was stabbed repeatedly, shot and nearly decapitated five years ago. Arias says she killed him in self-defense after he attacked her, but the grisly slaying caused even some anti-domestic-violence advocates to doubt her case.
Jurors found Arias guilty of first-degree murder a week ago.
But that was just the first of a series of decisions they must make in the case.
Under Arizona law, before they could consider imposing the death penalty, they had to answer a key question: Was Arias exceptionally cruel when she killed Alexander? They answered the question on Wednesday.
Defense attorney Kirk Nurmi had urged them not to be swayed by passion or emotion.
He said that adrenaline surging through Alexander's body at the time of the attack could have prevented him from feeling pain.
He also argued that psychological problems prevented Arias from knowing the pain Alexander was going through or understanding what was going on.
Martinez had argued that actions Arias took after the killing, like cleaning up the scene, made it clear that she understood what was going on.
As Martinez showed images of Alexander's wounds to the jury Wednesday, Arias cried and looked away.
After hearing testimony from medical examiner Dr. Kevin Horn and arguments from both sides, the jury began deliberating at 12:07 p.m. (3:07 p.m. ET). They announced they had reached a verdict nearly three hours later.
But the trial isn't over yet.
And Arias, who testified for 18 days during the trial, could speak to jurors again in court.
The jury's verdict Wednesday means the case moves to the sentencing phase.
That will be the defense's opportunity to ask the jury for leniency and present evidence to support why Arias should be spared the death penalty. Witnesses may include Arias' friends and family, and Arias could make a statement to the jury pleading for her life to be spared.
The jury then will deliberate for a third time to determine whether Arias should be sentenced to life or death. Its decision must be unanimous. In the case of a deadlock, a new jury would be chosen for this phase only.
There are currently 127 people on death row in Arizona. If Arias is given a sentence of death, she would be the fourth woman on death row in the state.
Minutes after the first-degree murder guilty verdict was announced last week, Arias said receiving a sentence of life in prison without parole would be the worst possible outcome.
"I said years ago that I'd rather get death than life, and that still is true today," she told Phoenix television station KSAZ. "I believe death is the ultimate freedom, so I'd rather just have my freedom as soon as I can get it."
