Sean Wayne Evans, 2, vanished from his family’s yard in Watertown, New York, on May 17, 1984, about 5:30 p.m. He was playing outside with his ball and his baby brother; his mother stepped inside to answer the phone and returned minutes later to find him gone. The ball was recovered near the bank of the Black River, which runs behind the property. Police say Sean may have fallen into the river, but extensive searches never recovered a body and the circumstances remain unclear; the case is classified as a non-family abduction. He was last seen in a yellow jacket, red pants and blue sneakers, with a birthmark between his shoulder blades and a scar on his forehead.

Does anyone who lived in the area in 1984 or who remembers that day have information that could help fill gaps in Sean’s disappearance?
