Scott Peterson was convicted of murdering his pregnant wife, Laci Peterson, and their unborn son, Conner, in 2003. He was sentenced to death, but the sentence was later overturned. He is now serving life in prison without parole.

The Los Angeles Innocence Project has filed a petition to overturn Peterson’s conviction, citing new scientific evidence and witnesses who support his innocence.

Attorneys with the Innocence Project argue that the break-in at the Medina home across the street from the Petersons’ and the subsequent arson of the burglars’ van were not properly investigated. They also allege potential Brady violations by the Modesto Police Department and the Stanislaus County District Attorney’s Office.

The attorneys further claim that medical research has advanced since Peterson’s conviction and now indicates Conner’s fetal growth was consistent with a date of death later than prosecutors presented at trial. Prosecutors maintain that Conner was likely expelled from Laci’s decaying body shortly before the remains were discovered.
