Cynthia Jean Hinds was 17 when she disappeared from Rainier Valley in Seattle in August 1982. Known to some friends as Cookie, she was last seen by family on August 11, 1982. A neighbor reported seeing her leave her apartment with an unidentified man in a red Cadillac; a few days later she was reportedly seen transferring from a similar car into a black Jeep near Seattle-Tacoma International Airport. That was the last confirmed sighting.

On August 15, 1982, Cynthia’s body was recovered from the Green River alongside Marcia Chapman. Investigators determined she had been strangled and linked her death to a series of killings later attributed to the Green River Killer. Reports from 1982 noted Cynthia had connections to the prostitution trade and that she and Opal Mills had recently painted apartments together.

In November 2001, Gary Leon Ridgway was arrested and later pleaded guilty to 48 counts of aggravated murder, including Cynthia Hinds. Her murder remains one of the early victims in the Green River cases. Did anyone who knew Cynthia or saw her in August 1982 come forward then or since with details about the red Cadillac or the black Jeep?
