About This Episode
What is this episode about?
The episode "Known Unknowns" from Dead Certain: The Martha Moxley Murder covers newly surfaced blood evidence found in a Belle Haven home, a potential new suspect in the Martha Moxley case, and a conversation with Amanda Knox about wrongful convictions. The episode also includes parting thoughts from Andrew as the series nears its conclusion.
The case behind the episode
The episode draws a direct line to Drabet på Meredith Kercher i Perugia 2007, the 2007 killing of 21-year-old British student Meredith Kercher in her apartment in Perugia, Italy. Kercher was stabbed to death on November 1, 2007. Rudy Guede was convicted in connection with the murder, while Amanda Knox and Raffaele Sollecito were definitively acquitted in 2015 after one of the most contentious trials in recent European legal history. Knox's own experience with wrongful conviction frames her contribution to this episode's discussion of the Moxley case and the broader risks of flawed investigations and rushed judgments.
