Secret police wiretap records in the Susan Powell case come to light for the first time, even as Susan Powell's parents fight for change in the state of Washington. This bonus episode takes you behind closed doors, into the private communications of Josh Powell, his brother Michael Powell, sister Alina Powell and father Steve Powell during "Operation Tsunami." What police learned by listening in on their phone calls helped explain why some officers feared for the safety of Susan's sons, Charlie and Braden, in the months leading up to their deaths at the hands of their father.

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
