Christopher Jason Swan was 4 years old when he went missing near the Susquehanna River in Sidney, New York, on November 11, 1981. He had been playing with his brother and another boy close to the riverbank and was last seen wearing a blue quilted coat, brown pants, and possibly a black hat with a white stripe.

Searches by local authorities used boats and scuba divers, and the community took part in thorough efforts, but no trace of Christopher was ever found and his body was never recovered. Because the recovery never occurred, it remains unclear whether he drowned or if another explanation applies; the case is still listed in the National Missing and Unidentified Persons System.

Anyone who was near the Susquehanna River in Sidney on November 11, 1981, or who has information about Christopher’s disappearance is asked to come forward.
