Summary based on the NamUs case record (MP2658) and 4 other sources
Ron Knutson, a 27-year-old man, was last seen on December 18, 1982, in Morongo Valley, California. A member of the Mescaleros Motorcycle Club, Knutson’s disappearance raised suspicions of foul play due to his affiliations and the circumstances of his vanishing. His vehicle, a blue Dodge with distinct modifications including dark-tinted windows and mag tires, was later found abandoned in Los Angeles.

Knutson had several tattoos, including the phrases "Ride to live, ride to die" and "Dane" (his nickname), along with various other designs on his arms and back. At the time of his disappearance, he was wearing glasses and was known for his long hair, beard, and mustache. Investigators suspect that Knutson’s disappearance may have been linked to criminal activities surrounding his involvement with the motorcycle gang, but his case remains unsolved.

Authorities have considered foul play in his case from the beginning, but no definitive leads have emerged over the years. His family continues to seek answers, and the case remains open. Anyone with information is urged to contact the San Bernardino County Sheriff's Department.
