Evil often lurks in the most unsuspecting of people, including those whom you thought you could trust. When the brutalized body of an eight year-old boy is found in the woods outside Gary, Indiana, investigators begin a decades-long search for a sadistic child-killer. And in 1997, a California mountain town is stunned by the murder of a longtime resident. Months of investigation bring the case to a shocking conclusion. These and other true life stories of deception and betrayal are brought to light in this season of Unusual Suspects.
