Since Friday, jurors have been deliberating evidence surrounding this key question: Did Arias kill ex-boyfriend Travis Alexander in self-defense? Or did she commit murder?
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 has caused even some anti-domestic violence advocates to doubt her case.
The jury, which has been in court since January 2, heard closing arguments on Friday. Jurors deliberated for 15 hours and five minutes.
As they took a lunch break after revealing they had reached a verdict Wednesday, some jurors were seen smiling and breathing sighs of relief. One juror returning from lunch wiped her eyes.
If they convict Arias of first-degree murder, they then will have to decide whether she lives or dies.
The trial began as both sides dramatically presented their arguments with details about Arias' love affair with Alexander.
"She rewarded that love from Travis Alexander by sticking a knife in his chest," prosecutor Juan Martinez said in his opening statement. "And you know he was a good man, according to her. And with regard to being a good man, well, she slit his throat as a reward for being a good man. And in terms of these blessings, well, she knocked the blessings out of him by putting a bullet in his head."
But defense attorney Jennifer Willmott countered: "Jodi Arias killed Travis Alexander. There is no question about it. The million-dollar question is what would have forced her to do it?"
Martinez accused Arias of playing the victim. He alleged she staged the crime scene to make it look like self-defense.
