On Monday, December 7, 2009, Josh Powell and his wife, Susan, failed to show up for work, or even call to say they'd be out that day. Their young sons, Charlie and Braden, are also no-shows at daycare, drawing the concern of extended family and friends. Before long, panic has set in, as nobody can find the missing family, despite extensive efforts to locate them. Soon enough, however, Josh Powell returns safely with the boys in his minivan, claiming they'd gone camping overnight in sub-freezing temperatures and a blinding snowstorm. When asked about Susan, he says he hasn't seen her since they left. Yet ... her purse is still in the house. And there's blood on the couch in the living room. What happened to Susan Powell? Join host Ryan Kraus for the final installment in this series.
