Kerry Ann Graham was 15 when she and her friend 14-year-old Francine Marie Trimble left Forestville, California, on December 16, 1978, reportedly to go to Coddingtown Mall in Santa Rosa. Graham told her mother she planned to shop for Christmas; neither girl was heard from again. Trimble’s mother filed a missing-person report within 24 hours; Graham was reported missing on Christmas Eve. Their families suspected foul play because there were no signs of disturbance at home.

On July 8, 1979, two bodies were found about 12 miles from Willits, California, near a remote section of Highway 20, buried in an embankment and concealed in duct-taped garbage bags roughly 80 miles north of Forestville. Both victims were in an advanced state of decomposition; the cause of death could not be determined, but the deaths were classified as homicides. Graham’s remains were at first misidentified as male before later genetic testing confirmed her identity; the bodies remained unidentified until November 2015.

Despite periodic reviews and speculation about links to other regional cases, no arrests or publicly identified suspects have been announced and the murders remain unsolved. If anyone knew Kerry or Francine, their movements that December day, or saw anything on Highway 20 near Willits in 1978–1979, please come forward with information.
