That night, Arias gave a series of media interviews from jail, telling reporters about her many fights with her legal team and her belief that she "deserves a second chance at freedom someday."
Arias, 32, contends she killed Alexander in self-defense when he became enraged after a day of sex, forcing her to fight for her life. Prosecutors say she attacked him in a jealous rage because he wanted to end their relationship and go to Mexico with another woman.
Her case became a sensation from the beginning as Arias gave a series of jailhouse interviews following her 2008 arrest in which she blamed the killing on armed, masked intruders.
She went on trial in January, and the case provided endless amounts of cable TV and tabloid fodder, including a recorded phone sex call between Arias and the victim, nude photos, bloody crime-scene pictures and a defendant who described her life story in intimate detail over 18 days on the witness stand.
The former waitress told jurors of an abusive childhood, cheating boyfriends, dead-end jobs, her sexual relationship with Alexander, and her contention that he had grown physically violent.
The trial was streamed live on the Internet and became a real-life soap opera to people around the globe. Some even traveled to Phoenix to attend the trial and became fans of the fiery prosecutor, Juan Martinez, who repeatedly tangled with Arias during her testimony. They sought his autograph outside court and had pictures taken with him, prompting the defense to argue for a mistrial. Their request was denied.
The verdict brings a close to the trial's penalty phase, which featured dramatic statements by Alexander's sister and brother as they described how their lives were shattered by the loss of their beloved sibling.
