Jenny Claire Campbell was 17 when she was found murdered in El Dorado County, California, on May 10, 1981. She had left her boyfriend’s house in Rancho Cordova in the early morning after an argument and was last seen hitchhiking. Later that day hunters discovered her nude body off Salmon Falls Road.

The scene indicated a brutal attack: her skull had been crushed by a rock found nearby, her body was partially covered with tree limbs, and her clothes and purse were scattered along the road. There were suspicions of sexual assault, though exact details remain unclear. Investigators have pursued various leads over the years, including consideration of known criminals such as James Leslie Karis Jr., but no charges were filed and the case remains open.

Anyone with information about Jenny, her movements that morning, or potential witnesses is asked to come forward.
