In September 1992, Tammy Haas was 19 and figuring out her next step in life. After attending a homecoming celebration in Yankton, South Dakota, she and her on-again-off-again boyfriend crossed the Missouri River to a farm party in Nebraska. By morning, Tammy was missing. Five days later, her body was discovered in a ravine near a golf course just across the state line. A broken neck. Conflicting statements. A trial that ended without conviction. More than thirty years later, silence still lingers in Yankton, and investigators believe there are people who know what happened that night. This Case Snapshot is dedicated to the memory of Tammy Haas. Produced by James Wolner. Research assistance by Mari Zoerb Hansen.
