Carole Sund, her teenage daughter Juli, and family friend Silvina Pelosso disappeared during a Yosemite-area trip in 1999 and were found murdered. The later killing of park naturalist Joie Armstrong led investigators to Cary Stayner, a motel worker. Stayner was convicted in the killings that had frightened visitors and devastated four families.
