Susan Caldwell was 17 when she was last seen in Seattle, Washington, on November 13, 1987. She was described as a Caucasian female with brown hair and brown eyes, five feet tall and about 140 pounds.

Very little is known about her life or movements that day; reports note a profound lack of information about her relationships, activities, or even whether Caldwell was her real surname. The investigation has long struggled for leads, and her profile in national databases such as NamUs offers few clues.

The case remains open with the Seattle Police Department but has grown cold, with no significant developments reported. If anyone knew Susan, her family, or has information about her whereabouts in November 1987, please come forward.
