Earlier this week, the California Supreme Court shocked the nation by overturning the death penalty of Scott Peterson, who was found guilty of the 2002 murders of his wife Laci and their unborn son Connor. Now, Peterson’s former mistress Amber Frey is breaking her silence to give her thoughts on the court’s decision.

Frey told Fox News that she is “relieved” that Peterson’s conviction was not overturned. She then added that the decision to retry Peterson’s penalty face should be left up to Laci’s family.

“I think that in making the decision as to whether to seek it again, the District Attorney should consult with Laci’s family and honor that decision,” Frey said.

Peterson had been on death row since 2005 for murdering his wife and unborn son on Christmas Eve in 2002. At the time, Laci was eight months pregnant with the baby boy. Afterwards, Peterson dumped their bodies in the San Francisco Bay from his fishing boat, and it took months to find them.

In Monday’s ruling, the court found that Peterson’s trial judge “made a series of clear and significant errors in jury selection that, under long-standing United States Supreme Court precedent, undermined Peterson’s right to an impartial jury at the penalty phase.”

Peterson’s sister Annie Bird spoke out after the death sentence was overturned to give her thoughts on the situation.

“I think that Scott Peterson is where he should be — in prison,” she said. “I lost my sister-in-law, Laci, and my unborn nephew, Conner. I am against the death penalty in principle for everyone. However, I do think that Scott Peterson is guilty and should spend the rest of his life in prison without the possibility of parole.”

His sister-in-law Janey Peterson felt a bit differently, saying that she was “sincerely grateful that the California Supreme Court recognized the injustice of Scott’s death penalty.”

“For a long and difficult 18 years, we have believed unwaveringly in Scott’s innocence, so today’s decision by the court is a big step toward justice for Laci, Conner and Scott,” she added.

The Peterson family is now waiting to see if Stanislaus County District Attorney Birgit Fladager will choose to pursue a new penalty phase trial.

“If the DA elects to do so, a new jury would be seated, and they would hear all the evidence,” Janey said. “They would then decide on Scott’s sentence. Life without the possibility of parole or the death penalty.”

She added that she is also waiting for the court “to address the new forensic and eyewitness evidence” that she believes will show Laci was alive the morning of Dec. 24 and ‘demonstrates Scott’s innocence.'”
