Police in West Valley City, Utah found a charred clump of metal hidden in the back of Josh Powell’s minivan on the day after Susan Powell first came up missing. They suspected it was evidence, but could never identify it. Now, on the 15^th anniversary of Susan’s disappearance, we reveal the likely origin of that mystery metal evidence. In this special bonus episode, you’ll also hear from Andrew Robinson, a witness who’s never before spoken publicly about what he saw in the days before Susan vanished.

For years, investigative reporter Dave Cawley has been studying thousands of police documents, journals, videos and diary entries. He 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.
