The company announced on Tuesday that they are making the series, with Liz Garbus (What Happened, Miss Simone?) directing, based on McNamara's book about her hunt to find the Golden State Killer.

Actor Patton Oswalt is helping to turn his late wife's final true crime book about the Golden State Killer into a TV docu-series following the arrest of her prime suspect.

Nearly immediately after its publication, HBO acquired the rights to I'll Be Gone in the Dark: One Woman's Obsessive Search for the Golden State Killer, Michelle McNamara's book chronicling her quest for the infamous California murderer active during the 1970s and '80s.

Before anyone knew his name, the 72 year old former cop terrorized California in the late '70s and early '80s.

The Golden State Killer is connected to 12 murders and about 50 rapes in California dating back to the 70' and 80's.

Prosecutors say they used DNA and a genealogical website to identify DeAngelo, decades after the case had gone cold.

I'll Be Gone in the Dark is McNamara's comprehensive exploration of the case, but also an insight into the investigator herself. She was working on the book when she died in her sleep in 2016 at the age of 46. The introduction was written by Gillian Flynn, who will be producing the documentary.

DeAngelo was an officer with the Exeter Police Department in the San Joaquin Valley from 1973 to 1976, and with the Auburn Police Department in the Sierra Nevada foothills northeast of Sacramento from 1976 to 1979.

Her book was published on February 27 and debuted at number one on the New York Times combined print and e-book bestseller's list.

There will be more as the story developes.
