premise: Thomas "Tommy" Lucchese (pronounced ] ; born Gaetano Lucchese, December 1, 1899 – July 13, 1967) was a Sicilian-born American gangster and founding member of the Mafia in the United States, an offshoot of the "Cosa Nostra" in Sicily. From 1951 until 1967, he was the boss of the Lucchese crime family, one of the Five Families that dominates organized crime in New York City.
hypothesis: Thomas "Tommy" Lucchese once had a boss.
reason: There is no way to know whether he once had a boss. We know he was the head of the family for a while, but before that, there is a good chance that he had a boss who was over him (as he made his way up) Or maybe he didn't. There is no way to tell for certain.
