Joan Cecilia Scaggs, 53, disappeared from her cabin at the Redwood Rest Resort in Boulder Creek, California, after she was last seen on November 12, 1983. That night her two sons visited around 2 a.m.; Joan let them in, then went to her bedroom and the sons left, locking the door behind them. When they returned the next morning, she was gone and her purse, medication, cigarettes, and clothes remained, with only her nightclothes and a high-altitude map reported missing.

Neighbors said they heard a car with a low-rumbling muffler about 3 a.m., then a car door slamming and voices. A child later reported hearing screaming that morning. Joan had health issues requiring medication and led a relatively isolated life; she had been upset about a son’s planned move to South Carolina. There are no other public clues and she has never been found.

Does anyone have memories of activity at Redwood Rest Resort in November 1983 or information about the car or people heard that night?
