A riveting meditation on obsession and loss, this six-part documentary chronicles the unrelenting path of a mysterious killer and the fierce determination of one woman to bring the decades-long case to light, giving voice to the survivors and their families. Directed by Academy Award(R) nominee and Emmy(R)-winning director Liz Garbus (HBO's Who Killed Garrett Phillips), the series, based on the book of the same name, explores writer Michelle McNamara's investigation into the dark world of a violent predator she dubbed the Golden State Killer who terrorized California in the 1970s and 1980s.
