John Howard Winer, 53, disappeared while visiting Niagara Falls, New York, in July 1976. He was last seen sitting on a railing near the falls wearing a dark green shirt and grey pants; a few personal belongings were found abandoned near that railing. There were no witnesses to what happened after he was seen, and the powerful currents and breadth of the Niagara River complicated search efforts.

The New York State Park Police handled the investigation but were unable to determine his fate. Decades later the case remains unsolved and his family received no definitive closure. If anyone was at the falls that day or remembers seeing John or his possessions, can you share what you recall?
