For more than 20 years, the murders of Laci Peterson and her unborn son, Conner, seemed like a closed case. But A&E's Scott Peterson: The New Evidence is challenging everything we thought we knew.

This week on Killer Thriller Docu, Jennifer Fessler sits down with veteran defense attorney and ABC News legal consultant Chris Pixley to unpack the explosive new documentary, the evidence that could change the case forever, and why the Los Angeles Innocence Project believes Scott Peterson may not have received a fair trial. From overlooked witnesses to new forensic analysis, this is a conversation that will leave you questioning one of the most notorious murder convictions in modern history.
