The head of the Gambino clan, one of the great families of the Italian-American mafia of New York, was shot dead Wednesday night outside his home.
Aged 53, Franck Cali had been running the organisation since 2015. He received six bullets in the chest.
The Gambino clan has since specialised in extortion, illegal gambling, credit card fraud or health insurance.
The assassination of Frank Cali comes a few days after the death, in prison, of Carmine Persico, chief of the Colombo clan, at 85 years old.
Gambino and Colombo are among the five great families of the Italian-American mafia of the northeastern United States, adding to them, the Bonanno, Genovese and Luchese.
