When cold case investigator Paul Holes came across the Golden State Killer file in 1994, he resolved to finally unravel the mystery of the serial killer who stalked Californians in the '70s and '80s. And in 2018, he did—Joseph J. DeAngelo, a former cop, was identified as the long-sought murderer. In Unmasked, Holes delves into his career as a crime solver, touching on infamous cases like the Golden State Killer, Laci Peterson's murder, and Jaycee Dugard's kidnapping. Holes will be joined in conversation by Emmy winner Yeardley Smith (the voice of Lisa Simpson) and Detectives Dan and Dave from the Small Town Dicks podcast.
