Carlos Marcello (born Calogero Minacore; February 6, 1910 – March 2, 1993) was an American crime boss of the New Orleans crime family from 1947 until the late 1980s. G. Robert Blakey and other conspiracy theorists have asserted that Marcello along with Santo Trafficante, Jr. and Sam Giancana masterminded the 1963 assassination of United States President John F. Kennedy in retaliation for federal prosecution that threatened their secret criminal organization’s increasingly profitable businesses and their multibillion-dollar international organized crime empires.
