On July 4, 1954, Trooper Arthur L. Lacroix, 23, died of injuries he sustained at the Edgewater International Speedway near Alexandria Bay. Trooper Lacroix stopped at the speedway to check on traffic conditions and observed a stock car overturned on the race course. As he went to the car to determine if the driver was injured, a wheel from another racer careened up an embankment and struck him in the chest and head. He was taken to E. J. Noble Hospital in Alexandria Bay and died in an ambulance while being transferred to a Watertown hospital for emergency surgery.
Trooper Lacroix joined the State Police in November 1953, and had been assigned to SP Chazy until he was transferred to SP Alexandria Bay.
