Well Monzon himself is dead, which doesn't help. A lot of the people closest to him (wives for example) probably wouldn't be willing to talk either. The man was a true enigma, one of the most violent personalities ever outside of the ring yet he never brought those emotions with him into fights. Pure physical freak as well, could do whatever he wanted before fights and during training without effect.
