James Zapolski, known as Jamie, was 15 when he left his home on Washington Street in Princeton, New Jersey, on July 23, 1966, for a routine bicycle ride and never returned. He was about to start his sophomore year at Princeton High School, had been training for a planned long ride to Florida on a recently purchased gold and white 15-speed French bicycle, and was last seen wearing a white sport shirt with blue stripes, white cut-off jean shorts, and sneakers.

The morning after his disappearance the bicycle was recovered in the Delaware-Raritan Canal at Griggstown, about five miles from his home. The bike’s Tour de France decal had been removed, and it was not linked to Jamie until a boy who had kept the bicycle saw a newspaper article in September and handed it to police. A search of the canal found no other evidence or sign of Jamie.

A 13-state police alert was issued and the case was investigated for decades, but no definitive answers were found and the family never learned what happened. Does anyone who lived in Princeton or along the Delaware-Raritan Canal in 1966 recall seeing a young rider matching Jamie’s description or any unusual activity that July?
