Lisa Lorraine Yates was 19 when she vanished from Seattle on December 23, 1983. She was last seen on Rainier Avenue, a part of the city then noted for being vulnerable to predators targeting young women. Her disappearance was not reported at the time.

On March 13, 1984, remains later identified as Lisa’s were found near Interstate 90 in North Bend, Washington. The condition of the remains prevented a precise determination of cause of death, but investigators classified the case as a homicide. The remains were officially identified as Lisa Yates in September 1984.

Her case remained unsolved for many years until developments tied her death to a broader series of killings in the Seattle area. Does anyone have information about Lisa’s life in Seattle in late 1983 or remember seeing her on Rainier Avenue that December?
