Summary based on the NamUs case record (MP26027) and 4 other sources
Stanley L. Post, a 42-year-old man, was last seen on March 24, 1990, in Imperial Beach, California. On that day, he departed from Shelter Island in his 16-foot white boat, which had a green stripe and an outboard motor, with the registration number 6690EC painted on the bow. Stanley told his roommates he was going fishing and was expected to return by nightfall. However, he never came back, and his truck and trailer were later found parked near the launch ramp.

At the time of his disappearance, Stanley was separated from his wife and working as a customer service representative for IBM. His supervisor, after noticing his absence from work, reported him missing. Despite extensive searches, neither Stanley nor his boat have ever been located, and the case remains unsolved.

Stanley was described as a 6-foot-tall white male with brown hair and blue eyes, weighing about 185 pounds. The circumstances of his disappearance suggest that he may have encountered trouble while out at sea, but no evidence has been found to confirm what happened. Authorities continue to investigate, and the San Diego County Sheriff's Department is leading the case.
