Summary based on the NamUs case record (MP37938) and 5 other sources
Robert Hay, age 27, was last seen on September 25, 1981, in San Francisco, California. At the time of his disappearance, Hay was staying at a receiving home in the city. He has not been heard from since that date, and few details surrounding his disappearance have emerged. Despite efforts to locate him, his case remains unsolved, and no significant leads have surfaced over the years.

Hay is described as a Caucasian male, standing about 5'8" tall and weighing approximately 120 pounds. He had blond hair, blue eyes, and was known to wear a partial set of dentures. On the day he was last seen, he was dressed in a sweater, blue jeans, and tennis shoes. His disappearance has been classified as a missing person case, and the San Francisco Police Department continues to investigate any potential leads.

With minimal information available, Hay's case remains a mystery. His name is listed in national missing persons databases, and investigators continue to seek public assistance in solving this decades-old case. Anyone with information is encouraged to contact the San Francisco Police Department to help bring closure to his family.
