NY media reported that 53-year-old Cali was shot multiple times outside his auto on Staten Island on Wednesday evening, local time, by an unidentified man who then fled the scene in a blue vehicle.
A 911 caller reported a blue pickup truck, which may have ran over Cali before or after the shooting, was seen driving away from the scene, according to WABC.
Among law enforcement officials, Cali was known as a "real quiet old-school boss" - one police source told the New York Post.
Mr. Castellano and Mr. Bilotti were each shot about six times in the head and upper body and fell dead beside the open doors of their black Lincoln limousine, which had been parked moments before on the south side of 46th Street in a "no standing" zone.
In 2012, Cali was identified as the new underboss of the Gambino crime family. Gotti died while in prison in 2002 of throat cancer and Gambino died in 1976.

Giovanni Gambino said that the 53-year-old was a constant feature in the NY charity scene and was a "good wise guy".
According to the New York Daily News, Cali, a native of Sicily, was part of the Gambino family ruling panel during this leadership vacuum. The New York Post reported that Cali had increased the Gambino family's involvement in drug trafficking, particularly in opioids. His wife and children were home at the time.
"We thought those days were over", Mayor Bill de Blasio said of Cali's slaying.
But Gravano would eventually testify against Gotti, leading to Gotti's 1992 conviction in five murders - one of several major convictions that thinned the Mafia ranks in the 1980s and 90s. "Very surprising, but I guess old habits die hard". He was sentenced to 16 months in federal prison and released in 2009. Zottola's son, Salvatore, survived an apparent assassination attempt in July outside his home, also in the Bronx.
In another burst of mob drama, authorities announced Thursday that a Gambino family associate of over a decade, Anthony Pandrella, was arrested for robbing and murdering his friend Vincent Zito.
The body of mafia crime boss Paul Castellano lies on a stretcher outside the Sparks Steak House in NY in December 1985 after he and his bodyguards were gunned down at the direction of John Gotti, who then took over as boss.
