Cold returns at the 10-year anniversary of Susan Powell's disappearance with new episodes focused on previously undiscovered evidence in the case. For this episode, we examine data from a GPS tracker that police hid on her husband Josh Powell's minivan the day after the disappearance. It reveals Josh visited several dumpsters in the days, weeks and months after Susan vanished. The tracking data also reveals Powell parked next to an Idaho canal late one December night.
