Samuel "Red" Levine was an American mobster, described as head of Lucky Luciano's hit squad of Jewish gangsters.

Murder, Inc. was an organized crime group active from 1929 to 1941 that acted as the enforcement arm of the National Crime Syndicate – a closely connected criminal organization that included the Italian-American Mafia, the Jewish Mob, and other criminal organizations in New York City and elsewhere. Murder, Inc. was composed of Jewish and Italian-American gangsters, and members were mainly recruited from poor and working-class Jewish and Italian neighborhoods in Manhattan and Brooklyn. It was initially headed by Louis "Lepke" Buchalter and later by Albert "Mad Hatter" Anastasia.
