West Valley City police did not act alone in their investigation of Susan Powell's disappearance. This bonus episode of Cold, first released in 2019 on the Wondery+ subscription service, focuses on the work of U.S. Marshal Derryl Spencer. He played "good cop" to Josh Powell and his father, Steve Powell, hoping to earn their trust during a pivotal period of the investigation. Spencer even secretly recorded a meeting with Steve Powell in Puyallup in the hopes Steve might slip up and reveal Susan's whereabouts.

For years, investigative reporter Dave Cawley has been studying thousands of police documents, journals, videos and diary entries. He has tracked down new sources, followed new leads and traced Josh Powell's trail from West Valley City, Utah, through Idaho, Oregon, Nevada and on to Washington State, where Powell killed himself and his two sons. Cold is the most complete retelling of the Susan Powell story ever. Join Dave Cawley in his search for truth. Share your thoughts: #ColdPodcast #FindSusan Twitter Instagram Facebook
