The Kidnapping of Barbara Mackle

Barbara Mackle, the daughter of a wealthy Florida real estate developer, was abducted from a motel room near Atlanta on December 17, 1968, by Gary Krist and Ruth Eisemann-Schier. She was buried alive in a fiberglass box with an air pump, food, water, and a light. After an $500,000 ransom was paid, Mackle was found alive 83 hours later. Krist was captured, convicted, and eventually pardoned; Eisemann-Schier was the first woman on the FBI's Ten Most Wanted list.
