“The Obfuscator” investigates the potential killer’s involvement in Kenley’s disappearance through interviews with the POI's family members and the help of a forensic hypnotist. “The Missing Link” Sarah MacDonald, Kenley’s mother, goes to meet this new person of interest, followed by an interview with the suspect's sister, who links her sibling directly with Kenley’s 1992 disappearance. The episode culminates with a Jane Doe letter received by the filmmaker that confirms many of these same details.
