Summary based on the NamUs case record (MP20186) and 4 other sources
David Martin Duenas, age 27, was last seen during the summer of 1984 in Garden Grove, California. He was working as a cook at the time of his disappearance. The exact circumstances of his last sighting are unclear, but over the years, his family has made numerous attempts to locate him without success. The date of June 20, 1984, is considered an approximation of his last known whereabouts.

Duenas is described as a white male, standing between 6'0" and 6'2", and weighing between 150 and 190 pounds. He had brown hair and hazel eyes, with tattoos that included an eagle on his left arm and crosses on his right forearm and left shoulder. Notably, he was missing his upper right tooth at the time of his disappearance. Despite his family’s continued efforts, no significant leads have emerged, and his case remains unsolved.

Authorities continue to seek any information that could provide closure in the case.

Last Seen: Jun 20, 1984
