Good guess, Mike's bodyguard, but the gangster who was identified by Kefauver as the top mobster in America was Abner (Longie) Zwillman, boss of the northern NJ rackets.
The first gangster killed by Tommygun fire in NYC was Capone's old mentor, Francesco Uole, aka Frankie Yale.
Q. Who was the only major mob boss to die in the electric chair?


Ntra la porta tua lu sangu � sparsu,
E nun me mporta si ce muoru accisu...
E s'iddu muoru e vaju mparadisu
Si nun ce truovo a ttia, mancu ce trasu.
