Tracy Sue Zandstra, 29, was last seen on November 16, 1991, at her home in Stirling City, California, where she lived with her boyfriend, Richard Pyle, and her two children. She disappeared about 2:00 a.m., leaving behind her belongings and her children. Foul play is suspected and her body has never been found.

In 2019 Richard Pyle was arrested in connection with Tracy’s disappearance; he was later acquitted in 2022. The case remains unresolved and Tracy’s whereabouts are unknown. Does anyone who knew Tracy or lived in Stirling City at the time have information that could help explain what happened that night?
