Crime Scott Peterson's Sister-in-Law Claims New Evidence Proves He's Innocent of Killing His Pregnant Wife Janey Peterson spoke on the Today show about new evidence that she believes will help her brother-in-law win a new trial and walk free By Steve Helling Published on August 25, 2021 01:40 PM Share Tweet Pin Email Scott Peterson.

His sister-in-law thinks so — and tells the Today show that the commonly accepted timeline of the Laci Peterson murder case is wrong. Scott was convicted of two counts of first-degree murder in the 2002 death of Laci and their unborn son, Conner. He was sentenced to death in 2005. He remained on death row until 2020, when his death was overturned, meaning that he would face a new penalty phase trial. In October, the California Supreme Court ruled that a lower court should take a second look at his case to determine whether his guilty verdict should be overturned and whether Scott, now 49, should face a new trial. In her interview with Today, Janey Peterson says that Laci was not killed on Christmas Eve 2002, but was killed later. "There's evidence that was completely ignored that shows Laci was alive after [Scott] left for the day," Janey, who is married to Scott's brother, told the show. "But also, there was no evidence that he had anything to do with what happened to Laci." Laci Peterson's Family 'Devastated' Scott Peterson Is Off Death Row: 'It's Beyond Painful' ZUMA Press. Laci was eight months pregnant when she disappeared from her Modesto home on Christmas Eve in 2002. Her body was found in April 2003 in San Francisco Bay. Scott claimed that Laci was killed by an unknown assailant as she walked the couple's dog after he left to go on a solo fishing trip on Christmas Eve morning. But as the case moved forward, jurors heard about Scott's dark secrets, including a months-long affair with a woman named Amber Frey, who was unaware that Scott was married when she started dating him. Frey later worked with prosecutors, taping damning phone calls with Scott. During trial, she testified for several days about her relationship with Scott, her realization that he was still married and that Laci had vanished. Frey first called police in Modesto in late December 2002 to disclose the affair. Want to keep up with the latest crime coverage?

Scott was convicted by a Redwood City jury in 2004. But in Wednesday's interview, Janey says that being an adulterer does not mean that her brother is a killer. "I don't think you can take that leap," she tells the morning news show. Today Scott will attend court virtually from California's San Quentin State Prison on Wednesday as part of his legal team's fight for a new trial. The defense team argues that his previous trial was flawed, in part because one of the jurors lied about being a victim of domestic abuse in order to get selected on the case.
