Francine Trimble
The murders of Kerry Graham and Francine Trimble are a currently unsolved double murder that occurred in December 1978, when both girls—aged 15 and 14 respectively—disappeared after leaving their homes in Forestville, California, to visit a shopping mall in Santa Rosa. Their remains were discovered in July 1979 approximately 80 mi (130 km) north of Forestville, concealed within duct-taped garbage bags and buried within an embankment of a heavily overgrown woodland area located beside a remote section of Highway 20, 12 mi (19 km) from the city of Willits. Due to the advanced state of decomposition of the girls' remains, the specific cause of death of each victim has never been established, although both girls' deaths have always been considered to be a homicide. Furthermore, Graham's body was mistakenly identified as that of a male until genetic testing proved otherwise. The bodies of Kerry Graham and Francine Trimble would remain unidentified until November 2015, when their identities were confirmed via the use of DNA profiling.
