Cynthia Moreland, 18, of Cotati, California, was murdered on October 11, 1980, while hiking at Point Reyes National Seashore. She and her 19-year-old fiancé, Richard Stowers, were both shot to death on Mount Wittenberg. Their bodies were not found until nearly two months later, when search dogs from the California Rescue Dog Association located badly decomposed remains.

The killings were later linked to David Joseph Carpenter, known as the Trailside Killer. Carpenter, a repeat sex offender living with his parents in San Francisco at the time, had been on parole after a lengthy prison term and was not listed on the state sex-offender registry or recent-release list. He was identified after a woman who had a prior disturbing encounter with him pointed him out to authorities.

Carpenter was convicted in trials moved to Southern California for multiple Marin County slayings, including the deaths of Moreland and Stowers; juries found him guilty of counts that included first-degree murder and rape. Anyone who knew Cynthia, Richard, or who has information about the Mount Wittenberg area at that time is asked to come forward.
