Richard William Moss, 22, was last seen by his mother on May 25, 2017, at their home in Montara, California. That morning he drove to work along California Highway 1 near Devil’s Slide, a stretch of road described as treacherous. Investigators later determined his vehicle went off the road and plunged more than 100 feet into the ocean near Montara State Beach.

No witnesses were known initially and authorities could not confirm the vehicle’s fate until July 13, 2017, when part of the car, including a wheel, washed up on the rocks at Montara Beach. Despite searches, Moss remained missing. In August 2018 a vertebra found on the beach was identified as belonging to Moss; no other remains have been recovered. His family has pushed for guardrails at Devil’s Slide as a safety measure.

If anyone saw Richard or his vehicle on May 25, 2017, or has information about conditions along Highway 1 that morning, please come forward.
