Arias, now 34, will spend life in prison and can no longer be given the death penalty, according to state law. On April 13, the judge will decide whether she spends life in prison with or without parole.
The trial made national headlines as details of the brutal crime emerged. Arias stabbed Alexander 27 times, slashed his throat and shot him. She tried to cover up the crime by erasing photos from his camera and throwing it in the washing machine.
During the trial, prosecutors told jurors that Arias planned the attack after Alexander invited another woman on a trip to Cancén. When interviewed, Arias first told police she knew nothing about the slaying, then said Alexander was killed by two masked gunmen, and then ultimately claimed self-defense.
