JoHanna Leatherbury was 17 when she was last seen late on August 20, 1971, leaving her Holladay home to meet friends. Witnesses placed her at a popular teen hangout called The Complex near 2100 South and State Street in Salt Lake City; she was seen getting into a car with at least two males and others. Her white Chrysler was found abandoned the next day on Westminster Avenue, and fishermen discovered her nude body in a canal near the Great Salt Lake about half a mile west of the then-abandoned Great Saltair entertainment complex.

An investigation determined she had been sexually assaulted, stabbed, and shot. Her purse and wallet were later recovered from the roof of a nearby motel. Early leads included two juveniles found with the purse and wallet and the driver of a brown International Harvester Scout seen near where the body was dumped; those individuals were cleared. The family says the case went cold, records were not shared with them, and her body was exhumed in 2017 for DNA testing as part of renewed efforts with the Utah Cold Case Coalition. Her killer has not been identified.

Does anyone have information about JoHanna, the people she was with at The Complex, or the brown Scout seen near the salt flats?
