Michelle and her editors agree to push her book deadline after being granted access to the Orange County Sheriff’s Department’s East Area Rapist / Original Night Stalker (EAR/ONS) room. Poring over 37 boxes of files now occupying her daughter’s playroom, Michelle and her researcher Paul Haynes explore the case of the “Visalia Ransacker,” the perpetrator of a string of burglaries in the early ‘70s bearing striking similarities to EAR.

As Michelle’s loved ones cope with her sudden death, her work to unmask the Golden State Killer lives on. Inspired by McNamara’s interest in genealogy and online DNA testing services, Paul Holes, Chief of Forensics in Contra Costa County, reconstructs the killer’s family tree with the help of genetic genealogist Barbara-Rae Venter. After inheriting Michelle’s 37 boxes of case files, researcher Paul Haynes and true crime writer Billy Jensen work alongside Michelle’s husband, Patton Oswalt, to finish her book, which becomes an instant bestseller. Meanwhile, the release of Michelle’s autopsy report rocks her inner circle.
