Who was the only deceased jockey to win a horse race?

The only deceased jockey to win a horse race is Frank Hayes. He achieved this remarkable feat on June 4, 1923, at Belmont Park in New York when he suffered a fatal heart attack during the race but remained in the saddle, allowing his horse, Sweet Kiss, to cross the finish line first. Hayes was subsequently declared the winner, making this a unique and tragic moment in horse racing history.
