Cali's murder is the first hit on a Mafia boss since John Gotti arranged the assassination of then-Gambino head Paul Castellano in 1985.
Castellano's reign as kingpin had begun in 1976 after the death of Carlo Gambino.
The family was headed by Domenico Cefalu until 2015, when Frank Cali took over as capo.
The Gambinos' rise to become one of the most powerful mafia families in America started in 1957, when the family's namesake, Carlos Gambino - an Italian immigrant - orchestrated the murder of Albert Anastasia, who had organized a collection of Italian gangs into what now would be considered a 'crime family.
John Gotti, who had been loyal to Dellacroce and didn't think Castellano was worthy of being the Don, and the irate Gambinos then decided to whack Castellano.
He fell to the pavement and died.
On December 15, 1985 Gotti and the Dellacroce devised a plan to assassinate Castellano and Bilotti - by luring the boss to a meeting at Sparks Steakhouse on 210 E.
