Summary based on the NamUs case record (MP117767) and 4 other sources
John Martin Marschall, 31, was last seen at his apartment in San Francisco, California, on November 2, 1985. At the time of his disappearance, Marschall was described as a white male, 6'2" tall, weighing 195 pounds, with brown hair and blue eyes. He also had a distinguishing feature—his tonsils had been removed. Marschall's case is classified as an endangered missing person, though few details about the circumstances surrounding his disappearance have been made public.

He has never been heard from again since that day, and his case remains unsolved. Despite the passage of time, there is still hope for answers, and his case is listed in multiple missing persons databases, including the California Department of Justice and NamUs. Authorities encourage anyone with information to contact the San Francisco Police Department.
