S13·E18 Church Dis-service

A young woman attends evening church services... then disappears. When her abandoned car is found, the tank is empty and a gas can she kept in her trunk for emergencies is missing. Eyewitnesses place her at a nearby gas station, getting into a van, but their descriptions of the vehicle don't match. Three days later when her body is discovered, the search for the driver of that van intensifies.
