Nellie Louise Davis was 35 when she vanished from Duvall, Washington, on January 27, 1975. She was reported missing to the King County Sheriff’s Office the same day. At the time she was last seen she had brown hair and blue eyes, stood 5 feet tall and weighed about 160 pounds, and was wearing a jacket of unknown color and tennis shoes.

Her case remains open and her information was entered into national missing-person databases. For the family, the disappearance has remained unresolved and the basic facts are limited to name, date, place and a brief physical description.

Did anyone in Duvall or King County remember seeing Nellie around January 27, 1975, or have information that could help fill the gaps in her timeline?
