Frank Iaconi (c. 1895 – July 14, 1956[1]) was an Italian American gangster who reigned as crime boss of Worcester, Massachusetts, from the days of Prohibition through 1953.
Iaconi enjoyed police protection, allegedly because he focused on gambling and forbade large-scale dope-dealing and prostitution.
Worcester was considered such a safe-haven for organized crime that the Mafia bosses held a conference there in 1950.
That was the same year that Iaconi ran afoul of the Kefauver Committee investigating organized crime.
In February 1953, Iaconi was indicted for failing to pay $217,875 in taxes on $350,000 in revenue from racketeering and for money laundering.
