I'll Be Gone in the Dark with subtitle

Writer Michelle McNamara, author of True Crime Diary, her blog about unsolved crimes, finds a new obsession in the “East Area Rapist” (EAR), who terrorized California in the 1970s and ‘80s and was, ultimately, responsible for 50 home-invasion rapes and 12 murders. Today, her husband, friends, and colleagues reflect on Michelle’s talent for bringing true crime stories to life.

Michelle reflects on the 1984 murder of her childhood neighbor Kathy Lombardo, which she credits with planting the seed for her lifelong fascination with unsolved crimes. Local detectives who worked the EAR case in the '70s - and citizen detectives who picked up where they left off - discuss a proliferation of serial rape cases in Northern California at the time.

In 1979, law enforcement is thrilled when the East Area Rapist (EAR) attacks abruptly stop in Northern California, but in reality, EAR has moved south to commit a number of gruesome murders in the Santa Barbara area, known as the “Original Night Stalker” series. The hunt for the perpetrator stalls due to lack of cooperation between jurisdictions and concerns of tarnishing the area’s pristine image, leaving the community unaware of the predator in their midst. David Witthuhn, the husband of murder victim Manuela Witthuhn, is questioned as the sole person of interest. Michelle’s article chronicling her investigation of the case, “In the Footsteps of a Killer,” causes a splash when it’s published 2013.

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. Overwhelmed by the amount of material and the graphic nature of the crimes, Michelle struggles to balance the demands of her self-described addiction to her work with her family life.

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.

As 72-year-old former police officer Joe DeAngelo’s arrest unfolds in real time, chilling facts materialize that illuminate Michelle’s prescience in her book’s epilogue, “Letter to an Old Man.” Researcher Paul Haynes and true crime writer Billy Jensen try to learn everything they can about DeAngelo. When Patton Oswalt, Jensen, and Haynes connect with survivors and McNamara’s fellow citizen detective Melanie Barbeau, Michelle’s absence is deeply felt. Series finale.
