Theresa “Terry” Rideout was 36 when she vanished over Labor Day weekend in 1994. She finished a shift at Burger King in Evansville, made the night deposit, and never came back to her home in Chandler, Indiana. A week later, her fiancé, Jack Barnett, died by suicide in a Mount Vernon motel room, leaving behind a note that never mentioned Terry. With her paycheck still unclaimed, and her belongings left behind, investigators suspect foul play – but three decades later, her body has never been found and her case remains unsolved.
