However, this sentence has been overturned and the California Supreme Court has been ordered to re-examine the case when it was discovered that a juror, Richelle Nice, committed prejudicial misconduct because she did not disclose that she had been involved in prior legal proceedings.
Peterson lived in Modesto in 2002, when the murders occurred.
Last Aug. 24, the California Supreme Court overturned the death sentence for Peterson. "And I think there's a very, very good chance that we may see a second Scott Peterson trial".
"The court added that there had been" a collection of obvious and important errors in jury decision which, under longstanding United States Supreme Court precedent, jeopardized Peterson's right to an unbiased jury in the punishment stage".
The court agreed with Peterson's argument that potential jurors were improperly dismissed from the jury pool after saying they personally disagreed with the death penalty but would be willing to follow the law and impose it.
Investigators said that over 10,000 tips, considered parolees, and convicted sex offenders were chased as possible suspects. Peterson was eventually arrested after Amber Frey, a massage therapist living in Fresno, told police that they had begun dating a month before his wife's death, but that he had told her his wife was dead. Scott Peterson told police he had left their Modesto home that morning to go fishing in Berkeley. There were no records of an abusive relationship, though Scott Peterson was having an affair at the time.
"Peterson claims his trial was faulty for many reasons, starting with the odd number of pretrial publicity which surrounded the situation", the court stated in its judgment, according to In Touch.
Birgit Fladager, the current district attorney for Stanislaus County, did not immediately respond to a request for comment.
Newsom was said to be a longtime opposition of the death penalty.
Newsom said that he knows people think eye for eye, but he argued that "if you rape, we don't rape". "We're better than that", he was quoted in a New York Times report.
