Diane Marie Schulte, 22, was last seen at the couple’s home on Delaware Avenue in Nampa, Idaho, on the morning of March 25, 1977. Her husband, Fred Thomas Schulte Jr., reported leaving for work about 7:20 a.m.; he said Diane was home and not feeling well. When he returned that evening she was gone. Diane’s purse, money and car were left at the house, and her three cats were secured in a spare bedroom as was her usual practice. Her wedding ring and watch were found on a desk, items she reportedly only removed if she was at home or planning to be away for a very short time.

A week later, on April 3, 1977, Fred Schulte was found dead in Diane’s car after a high-speed crash on Highway 95; investigators ruled his death a suicide from a self-inflicted gunshot wound.

Diane was described as extremely introverted and a homebody who enjoyed reading, macrame and caring for her cats; she was estranged from her parents but spoke often with her grandmother in Michigan. Her disappearance remains unsolved and she has not been seen or heard from since March 25, 1977. If anyone knew Diane, her routines or has information about that week in Nampa, please come forward.
