On February 22, 1952, Trooper Patrick F. O'Hara, 24, was accidentally shot and killed on Route 20 near the hamlet of Bridgewater.
Trooper O'Hara responded to help another Trooper who had been assaulted and shot at by three escapees from the Herkimer County Jail. Trooper O'Hara captured the three suspect and secured the prisoners in the Troop car. Trooper O'Hara entered the vehicle to drive and his partner entered the rear of the vehicle with his rifle. As the door was shut, it struck the rifle, causing it to discharge. A round passed through the driver's seat and struck Trooper O'Hara, killing him instantly.
Trooper O'Hara joined the State Police on June 16, 1949 and was assigned to the Oneonta Station at the time of his death.
