Patton Oswalt opens up about Michelle McNamara's accidental overdose: ‘There were signs that I didn’t know to look for’

"I’ll Be Gone in the Dark" chronicles the decades-long manhunt for California’s notorious Golden State Killer, which finally ended in 2018 when authorities charged Joseph James DeAngelo with a long list of rapes and murders committed between 1974 and 1986. But the HBO docuseries is first and foremost the story of celebrated true crime author, Michelle McNamara, who came close to cracking the case in the pages of the posthumously published book that the series is based on. McNamara died suddenly in 2016 — two years before DeAngelo’s arrest — and her husband, comedian and actor Patton Oswalt, frankly addresses the circumstances of her passing in the series, acknowledging that she developed an opioid addiction that she kept hidden from her family.
