On October 13, 1980, 26-year-old Anne Evelyn Alderson was attacked and later found dead near the Cushing Memorial Amphitheater in Mount Tamalpais State Park, Marin County, California. Her body was discovered on October 15, 1980, with gunshot wounds and evidence of a struggle; investigators reported she had been raped and shot. Anne had been an avid runner and a former Peace Corps volunteer in Bogotá, Colombia.

Anne’s killing was the third similar attack on Mount Tamalpais within a year and became linked to a series of assaults on secluded trails in Northern California between 1979 and 1981. Those attacks involved approaching hikers, sexual assault, and fatal shootings, creating fear among local trail users.

Does anyone have memories of Anne, her running routes, or information about the trail area around the amphitheater that could shed light on her movements in October 1980?
