Well-Known Member. I asked Ron about that before he died and he told me that there wasn't a shred of truth. Frederick Percival Mills was an English boxer, and the world light heavyweight champion from 1948 to 1950.It is claimed he was shot dead by feared gangster Reggie Kray after he was found in the back seat of his silver Citroen DS19 sports car with a bullet wound.
