Summary based on the NamUs case record (MP6863) and 8 other sources
George F. Mateo, a 53-year-old man, was last seen on June 10, 1989, fishing near the Mohawk River in Amsterdam, New York. Mateo had been fishing on the north side of the river close to Lock 10 of the barge canal. His car was discovered abandoned the following day on Conrail property, located on the opposite side of the river from where he was last seen. Despite an extensive search of the river and surrounding areas, no sign of Mateo was found.

Mateo was 5'8", weighed 160 pounds, and had gray hair and blue eyes. He was last seen wearing a dark-colored baseball cap and carrying a backpack. At the time of his disappearance, he had been living in a local hotel in Amsterdam. His case has been classified as "lost/injured missing," and while authorities continue to investigate, no new leads have emerged over the years. His family has had no contact with him since that day, and his disappearance remains unsolved.

If anyone has information regarding the case, they are urged to contact the New York State Police.
