Chief of Detectives Dermot Shea says that he and his NYPD constituents are unclear as to Carmello's motives, but they're sure it's him in the surveillance footage.
The NYPD has "an arrest warrant in hand from the Richmond County DA's office", Shea said during the news conference, adding that the suspect's arrest will happen upon coordination with prosecutors in New Jersey. "Was the person paid to do it?"
But sources said Cali - who helmed a family notorious for gambling, loan sharking, and its deadly trade in heroin and oxycodone - thought Comello was trouble, sources said.
Surveillance video of the killing showed a man, allegedly Comello, crash his auto into Cali's parked SUV, drawing Cali outside in what might have been a ploy to lure him out of the house, Shea said.More news: UK Parliament votes to delay Brexit but rejects second referendum

Shea said police have recovered the truck but have not recovered the gun used in the murder. Comello's truck was issued a parking summons in Staten Island on the day of Cali's murder, Shea said. Information on an attorney for Comello wasn't immediately available.
The Gambino family was once among the most powerful criminal organizations in the US, but federal prosecutions in the 1980s and 1990s sent its top leaders to prison and diminished its reach.
Cali's only mob-related criminal conviction came a decade ago, when he pleaded guilty in an extortion scheme involving a failed attempt to build a NASCAR track on Staten Island.
Crime Scene investigators work at the scene where, reported New York Mafia Gambino family crime boss, Francesco "Franky Boy" Cali, was killed outside his home in the Staten Island borough of New York City, U.S., March 14, 2019. He was sentenced to 16 months behind bars and was released in 2009.
