Patricia Michelle Barczak was 19 when she disappeared from the Pacific Highway South area of SeaTac, Washington, near the Seattle–Tacoma International Airport on October 17, 1986. A culinary school graduate who hoped to become a baker, she had been working in sex work in that corridor when she vanished, leaving her family with years of unanswered questions.

A Department of Transportation survey crew found a human skull near Highway 18 in Auburn on February 3, 1993; dental comparison later identified the remains as Patricia’s. The skeletal condition prevented determination of an exact cause of death, but the case has been classified as a homicide. The discovery site was close to where remains of other victims linked to the Green River killings had been recovered, and Patricia’s mother described the ongoing uncertainty as pure hell.

Does anyone have information about Patricia’s movements in October 1986 or who she might have been with that day?
