Michelle McNamara tried to write I'll Be Gone In The Dark: One Woman's Obsessive Search For The Golden State Killer. Unfortunately she died in her sleep at age 46 before it was completed. Two other crime writers and her ex completed the book for her. McNamara is credited with coining the term "The Golden State Killer." The book was released in February of 2018 which was 2 years after her death and 2 months before the criminal was discovered.The criminal was Joseph James De Angelo, a former police officer. McNamara's work kept up public interest in the case but didn't speed up or help the process.
