PHOENIX (Reuters) - An Arizona jury reached a verdict on Wednesday in the trial of Jodi Arias, the California woman accused of killing her ex-boyfriend in a sensational case involving "sex, lies and dirty little secrets" that has snared media attention since January.
The Maricopa County Superior Court said the jury verdict will be read at 1:30 p.m. local time/4:30 p.m. EDT (20:30 GMT).
Arias, 32, could face the death penalty if convicted of murdering 30-year-old Travis Alexander, whose body was found in the shower of his suburban Phoenix home in June 2008. He had been shot in the face, stabbed multiple times and his throat had been slashed.
Arias has admitted to killing Alexander, but said it was in self-defense after he attacked her because she had dropped his camera while taking photos of him in the shower.
The jury reached its verdict on the third full day of deliberations. Judge Sherry Stephens, who gave them the case on Friday afternoon, had instructed jurors that they could consider the charges of first- and second-degree murder or the lesser charge of manslaughter, and that they should reach a unanimous verdict. First-degree murder requires proof of premeditation.
The trial, which began in early January and was punctuated by graphic testimony and evidence including a sex tape, was streamed live on the Internet and drew widespread media attention.
During the trial, the court heard how the petite, dark-haired Arias met and began dating Alexander, a businessman and motivational speaker, in 2006.
During 18 days of often gripping and salacious testimony, Arias said that she and Alexander continued to have sex despite their break-up from a relationship that was marked by emotional and physical abuse.
Arias said Alexander had made her feel "like a prostitute" and that he kicked and attempted to choke her, although she admitted never reporting the alleged abuse to the police, seeking medical treatment or documenting it in her journal.
Defense attorney Kirk Nurmi said Arias had snapped in the "sudden heat of passion" in the moments between a final photograph she took showing Alexander alive and taking a shower and a subsequent picture showing him covered in his own blood.
ARIAS PORTRAYED AS MANIPULATIVE
Prosecutor Juan Martinez painted a different picture of Arias, portraying her as manipulative and prone to jealousy in previous relationships, and said she had meticulously planned to kill Alexander.
"Nothing indicates that this is anything less than a slaughter," he told jurors in his summing up on Friday, asking them to return a verdict of felony first-degree murder.
Martinez accused Arias of bringing the pistol used in the killing, which has not been recovered, with her from California, and said she rented a car, removed its license plate and bought gasoline cans and fuel to conceal her journey to the Phoenix suburbs to kill Alexander.
Martinez said that Arias lied after the killing to deflect any suspicion that she had been involved in his death, leaving a voicemail on Alexander's cellphone, sending irises to his grandmother and telling detectives she was not at the crime scene before changing her story.
The jury had more than 100 questions for Arias. They grilled her on her claims that her mind went blank after she shot Alexander, and wanted to know why she had not called emergency responders - questions she struggled to answer.
The defense called a psychologist who testified that Arias' memory lapses stemmed from post-traumatic stress as a result of Alexander's alleged abuse and the killing itself - claims disputed by prosecutors.
In closing arguments, Martinez told the jury Alexander had sent an instant message weeks before his death saying he was "extremely afraid" of Arias because of her "stalking behavior."
Nurmi also reminded the jury that Arias was charged with murder and not with lying.
"Did she lie? Of course she did, but that's not in your verdict instructions," he said.
