On October 15, 1976, Carlo Gambino died at home of natural causes. Against expectations, he had appointed Castellano to succeed him over his underboss Dellacroce. Gambino appeared to believe that his crime family would benefit from Castellano's focus on white collar businesses. Dellacroce, at the time, was imprisoned for tax evasion and was unable to contest Castellano's succession. Castellano's succession was confirmed at a meeting on November 24, with Dellacroce present. Castellano arranged for Dellacroce to remain as underboss while directly running traditional Cosa Nostra activities such as extortion, robbery, and loansharking. While Dellacroce accepted Castellano's succession, the deal effectively split the Gambino family into two rival factions.
