Francine Trimble was 14 when she disappeared from Forestville, California, in December 1978 after leaving with a friend, Kerry Graham, to visit a Santa Rosa shopping mall. Their remains were recovered in July 1979 in a shallow grave in woods off Highway 20 near Willits, about 80 miles north of Forestville; the bodies were wrapped in plastic, bound with duct tape, and appeared to have been disturbed by wildlife.

Advanced decomposition complicated the initial investigation and led to a misidentification that included one victim being thought male. A re-examination and extensive forensic work finally identified Francine and Kerry in 2015. No clothing was found with the remains; a single bird-shaped earring believed to be Francine’s was recovered. Authorities have not been able to determine a definitive cause of death but have long treated the case as homicide and suspect the girls may have been killed elsewhere and moved to the discovery site.

Does anyone have information about Francine, Kerry, or their last known movements in December 1978 that could help bring new leads?
