Summary based on the NamUs case record (MP29858) and 5 other sources
Harold Elmer Martin, a 60-year-old U.S. military veteran, was last seen on November 1, 1984, at a Veterans Affairs hospital in Ventura, California. At the time of his disappearance, Harold was battling terminal lung cancer, and he also had a large tumor on the right side of his forehead. Standing at 5'3" and weighing approximately 115 pounds, Harold had gray hair, blue eyes, and a scar from a previous hernia operation. Notably, he had no natural teeth at the time of his disappearance.

Harold left the hospital on the day he was last seen and has never been heard from since. His case has remained unsolved, with very few details emerging over the decades. His disappearance is classified as an endangered missing person case, given his severe medical condition and the lack of any contact since he went missing. The Ventura Police Department continues to handle the investigation, but as of now, no significant leads have surfaced to explain what happened to him.
Last Seen: Nov 1, 1984
