Krista Kay Blake was 20 when she vanished from Vancouver, Washington. On July 11, 1974, she was last seen at about 5:30 p.m. getting into a light blue 1973 Ford van at a convenience store at 29th and K streets after hitchhiking from Orchards. Witnesses later saw Blake and a man in the van near Lewisville Park; she disappeared soon afterward.

Her remains were found in 1976 and a forensic examination of a jawbone confirmed her identity. Investigators focused on Warren Leslie Forrest, who owned a van matching the description and who became the primary suspect after a 1974 kidnapping survivor identified him. Forrest was charged with first-degree murder in October 1978; testimony at his 1979 trial from a survivor of an earlier attack contributed to his conviction for Blake’s murder and he received a life sentence.

Forrest has been linked by investigators to several other young women last seen hitchhiking and entering a van. Did anyone in the Vancouver or Orchards area recall Blake, the light blue 1973 Ford van, or seeing her near Lewisville Park that July evening?
