Desiderio Castillo was 31 when he was last seen on November 1, 1987, in Barstow, California. At the time he was living between Barstow and Detroit, Michigan; his disappearance followed a disagreement with family and he left the scene and never returned.

Castillo is described as 5 feet 7 inches tall, about 130 pounds, with black hair. His family searched for him, including trips to Michigan, and the case remains listed in missing persons databases but has produced no significant leads.

If anyone knew Desiderio, saw him around Barstow or Detroit in November 1987, or has information that might explain his movements after he left, please come forward.
