Information on a lawyer for Comello was not immediately available.
Among the mafia, apparently, a lone individual does not carry out hits and it is disrespectful to kill a rival at his home. So...
Mr Comello's truck was issued a parking summons in Staten Island on the day of Cali's murder, Mr Shea said.
An unspecified dispute between the killer and Cali - not linked to the mob - is an "angle that is being explored" for a motive, a New York Police Department source said.
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.
Tesla's new Model Y isn't all that exciting - and that's by design
He expects the Model Y's journey to the mass market to provide another wild ride for the company, its investors and customers. Ramsey, though, remains skeptical about whether the company will have adequate manufacturing capacity for the Model Y .
Comello was being held Saturday at the Ocean County Jail in New Jersey, after being picked up in the early hours of Saturday by federal marshals at a house in Brick.

Police are looking into whether this was the work of an organized crime gang, or a faction inside the Gambino family, including John Gotti's brother, Gene, who was just released just months ago after serving 29 years for dealing heroin. News accounts since 2015 said he had ascended to the top spot.
The last Mafia boss to be rubbed out in New York City was Gambino don "Big Paul" Castellano, who was assassinated while getting out of a black limousine outside a high-end Manhattan steakhouse in 1985.
"This was not a random act", NYPD Chief of Detectives Dermot Shea said Saturday during a press conference announcing the arrest.
After Gotti died in prison in 2002 the mob's influence on the U.S. eastern seaboard waned, but Cali's murder put it back in the headlines.
