Scott Peterson's defense attorney has announced claims of new evidence that could potentially lead to a judicial review of his murder conviction, according to recent statements made ahead of an upcoming documentary about the case.

Peterson was convicted in 2004 for the murders of his pregnant wife Laci Peterson and their unborn son Conner in Modesto, California. The case attracted national attention and resulted in Peterson receiving a death sentence, which was later commuted to life in prison without parole.

The attorney's announcement comes as a documentary about the high-profile case is scheduled for release this summer. However, specific details about the nature of the purported new evidence have not been disclosed publicly.

Peterson has maintained his innocence throughout the legal proceedings. His case has been the subject of multiple appeals over the years, with various legal challenges raised regarding evidence and trial procedures.

The California Supreme Court previously overturned Peterson's death sentence in 2020, citing issues with jury selection, though his conviction was upheld. Any new evidence claims would need to meet legal standards for post-conviction relief to prompt court consideration.
