Tonya Lee Clemmons was 26 when she was last heard from in Seattle on November 5, 1983. She is described as a Black woman, 5 feet 4 inches tall, about 120 pounds, with black hair, brown eyes and a deformity in her left arm. The last confirmed contact was November 5, 1983, but her disappearance was not reported to the Seattle Police Department until November 5, 1984, when a relative said they had not seen or heard from her in nearly a year.

Investigators have little information about the circumstances leading up to her last known contact, and no remains have been found. In May 1993 the case was linked to Gary Ridgway, the Green River Killer, because of where she was last known to be and her known presence in areas associated with sex work; that link is described as a strong suspicion, not a confirmed connection. The Seattle Police Department continues to list the case as open.

If anyone knew Tonya, saw her around November 1983, or has information that could help resolve her disappearance, please come forward.
