This is such an odd case. I wonder if the mystery will ever be solved. I hope so. Sad that someone can just vanish and never be heard from again.

Ronald Henry Tammen was a 19-year-old sophomore at Miami University in Oxford, Ohio, when he vanished from his Fisher Hall dorm room the night of April 19, 1953. A resident advisor, varsity wrestler and musician, he was last seen around 8:30 p.m., reportedly studying a psychology text after requesting fresh sheets because someone had put a fish in his bed. His roommate returned about 10:30 p.m. to find the lights on, the radio playing, an open book on the desk and Tammen’s wallet, keys, watch and coat still in the room. His car remained parked on campus.

Searches by campus security, local police and hundreds of students turned up nothing. A woman in Seven Mile, Ohio, about eight miles away, later said a dazed young man matching Tammen’s description asked for directions to a bus stop early April 20, though the bus service had been suspended that night. Five months earlier Tammen had visited the county coroner to request a blood test, a detail investigators called unusual. A 2009 DNA comparison with an unidentified body found in Georgia produced no match, and demolition of Fisher Hall in 1978 yielded no clues.

No conclusive explanation has emerged; theories range from foul play to amnesia or a mental breakdown. Does anyone have memories, family connections, or information about campus life in 1953 that could shed light on Ronald Tammen’s disappearance?
