NY police are hunting the hitman who gunned down Francesco "Franky Boy" Cali on Wednesday - witnesses and officials say the killer then made sure the 53-year-old Gambino mob boss was dead by running over him with a blue pickup truck.
Cali, 53, was shot six times in the chest, and run over by a blue pickup truck on Hilltop Terrace near Four Corners Road in Todt Hill about 9:15 p.m. Medics took him to Staten Island University Hospital, where he died.
According to a 911 call made by someone in the Cali home, the crime kingpin was also run over before he was shot, though the Daily News police sources say that claim is still under investigation.
Cali was named head of the family in summer 2013, DNA Info reported at the time, taking over total control of the more than 750-person organization.
He had pleaded guilty in an extortion conspiracy involving a failed attempt to build a NASCAR track in Staten Island.
The Gambino criminal organisation is one of the "Five Families" of organised crime in NY, alongside the Bonanno, Colombo, Genovese and Lucchese families.
Rising Gambino family mobster John Gotti allegedly ordered the hit on Castellano.
"The Gambino crime family during Castellano's reign was the largest criminal organization in the US, with law enforcement estimating it had some 250 "'made" members" and "more than 550 lower-ranking "associate' members".
An alleged mafia boss has been reportedly been shot and killed outside his home in NY.
A law enforcement official confirmed the victim was a high-ranking member of the Gambino crime family and is believed to be the acting boss.
A native of Sicily, Cali has deep mob roots, and his wife is the niece of Gambino capo John Gambino.
Last October, 71-year-old Sylvester Zottola of the Bonanno family was shot dead while waiting in his auto for an order from a Bronx McDonald's. The 85-year-old was serving a 100-year federal prison sentence after his conviction on racketeering and murder charges in the famous mid-'80s "Commission trial".
