Ron Knutson was 27 when he was last seen on December 18, 1982, in Morongo Valley, California. A member of the Mescaleros Motorcycle Club, his disappearance drew early suspicion of foul play because of his club affiliations and the circumstances surrounding his vanishing.

His blue Dodge, noted to have dark-tinted windows and mag tires, was later recovered abandoned in Los Angeles. Knutson wore glasses and was known for long hair, a beard and mustache. He had several tattoos, including Ride to live, ride to die and Dane, the latter a nickname, plus other designs on his arms and back.

Authorities have treated the case as possibly connected to criminal activity tied to the motorcycle gang, but no definitive leads have emerged and the case remains open. Anyone with information is asked to contact the San Bernardino County Sheriff’s Department.
