Jimmy Alto´s real name was Vincenzo Altomari. He died around 1959/1960. Lowkey made Genovese soldier. Why D´Arco described him as having no boss is a mystery to me. Could be that Capeci somehow is fooled by the Della Universita story that circulated the internet some time ago, and decided to put parts of it in the book. Jimmy Alto is listed by the FBI as a made member in their early listings. Della Universita is not.
