Helen Leone Dymond, 48, disappeared the night of June 28, 1981, after leaving a gathering at the Tilden Township Club in National Mine, Michigan. After an argument with her husband, who drove off and told her to walk home, she returned inside briefly and then left alone shortly after midnight intending to walk about a mile to her son’s house. She was last seen walking south on County Road 476 wearing blue jeans, a purple jacket, moccasins, and her prescription glasses.

Two months later the purple jacket was found on a foot trail near Switzer Reservoir about 75 feet from the road; family members identified it by unique buttons and a missing drawstring, though law enforcement initially doubted the identification because the jacket did not appear exposed to weather for two months. Reports also describe wide tire tracks in a clearing near the club where cars did not normally go and a woman’s loafer found there that was later discarded before it could be examined. Helen’s husband was questioned, passed a polygraph, and was cleared. The case remains open with the Michigan State Police and has been reviewed by Northern Michigan University’s cold case program; the family has offered a $5,000 reward for information leading to an arrest and conviction if foul play was involved.

Does anyone have memories from National Mine or the Tilden Township Club area in late June 1981 that might help Helen’s family?
