Mary Sue Bello was 25 and last seen on October 10, 1983. Her remains were found on October 12, 1984, and investigators determined she had been killed on October 11, 1983. Bello’s body was recovered from a location consistent with other victims whose remains were dumped in wooded, overgrown areas in the Seattle–Tacoma region.

Bello’s death became part of a larger series of murders that terrorized the area through the 1980s and 1990s, involving vulnerable young women whose bodies were placed in similar sites. A multiagency task force later investigated the related killings as a connected pattern.

Are there details about Mary’s life, last known movements, or anyone who saw her in October 1983 that could help clarify what happened?
