In this classic episode of Forensic Files, the longest running true crime series in television history, Eileen and Derrick Severs disappeared from their home in the small village of Hambleton in Great Britain, and police found evidence which suggested foul play. Careful analysis of a soil sample would tell investigators not only what happened to the couple, but who was responsible for the dirty deed. Originally aired as Season 2, Episode 2. (thetvdb.com)
