Frederick David Coole was 44 when he was last heard from in Tunkhannock, Pennsylvania, on August 10, 2011. He is a white male, 5 feet 8 inches tall, about 140 pounds, with gray or partially gray hair, blue eyes and a tattoo on his left shoulder. His disappearance was reported to the Pennsylvania State Police on August 21, 2011.

Severe flooding struck the area around the time he vanished, and that weather has shaped the main theory: that he may have been a flood victim. The Pennsylvania State Police in Tunkhannock continue to list the case as open, and his information is entered in NamUs to allow cross-checking with unidentified remains.

Few concrete leads have emerged and no definitive conclusion has been reached. If anyone has information about Frederick’s whereabouts, please share what you know with the Pennsylvania State Police in Tunkhannock.
