Colin Gillis was 18 and home from SUNY Brockport when he disappeared after a party in Tupper Lake, New York. On the night of March 10, 2012, he left a gathering on Paskugameh Road after an altercation and was last seen at about 1:45 a.m. on March 11, walking along State Route 3 near the Franklin–St. Lawrence county line toward Piercefield. He wore a white and black striped American Eagle shirt, blue jeans and red Nike Air high-top sneakers, and may have been carrying an orange L.L. Bean backpack containing a reversible red and black coat.

Family reported him missing that evening, prompting a large search involving state police, local police, the Department of Environmental Conservation and hundreds of volunteers. Some personal items, including his driver’s license, were found on the roadside near where he was last seen, but Colin, the orange backpack and the coat were not located. In November 2020 investigators excavated a property in Edwards after a tip; authorities have not announced results. A $25,000 reward is offered for information.

Colin remains classified as an endangered missing person and the circumstances of his disappearance are unresolved. If anyone knew Colin, saw him that night, or has information about the route between the party and State Route 3, please come forward.
