HBO Documentary Films has acquired the rights to journalist Michelle McNamara's bestselling book I'll Be Gone in the Dark: One Woman's Obsessive Search for the Golden State Killer, to develop as a docuseries. Deadline reported that McNamara, the late wife of Patton Oswalt, "was in the midst of writing the book when she unexpectedly died in her sleep in 2016. The book was completed by McNamara's lead researcher Paul Haynes and a close colleague, Billy Jensen, and framed by an introduction by Gillian Flynn and afterword by Oswalt, who also executive produces the docuseries."
"HBO taking on this story will advance the passionate pursuit that Michelle shared with dozens of men and women in law enforcement--to solve the mystery of one of California's most notorious serial killers," said Oswalt.
Last month, the Sacramento Sheriff's Office arrested former police officer Joseph James DeAngelo and charged him with a number of the crimes.
