Potential Hit Man in Police Custody in the Shooting of Frank Cali, Reputed Godfather of the Gambino Crime Family #Breaking

New York City detectives have a 24-year-old man in custody related to the shooting death this week of reputed crime boss Francesco "Franky Boy" Cali.

"The investigation is still in progress and an arrest has not yet been made," NYPD Assistant Chief Patrick Conry wrote in an email.

Conry said the 24-year-old was taken into custody early Saturday, but he did not say where. More information is expected to be released Saturday afternoon.

Citing "sources familiar with the investigation," NBC 4 New York reported the 24-year-old was arrested in Brick, New Jersey.

Cali, 53, died at a hospital after being shot multiple times in the torso in front of his home at 25 Hilltop Terrace in Staten Island. Police found Cali wounded after receiving a 911 call reporting an assault in progress about 9:15 p.m. Wednesday.

Federal prosecutors have referred to Cali in court filings as the underboss of the Gambino family, saying he was connected through marriage to the Inzerillo clan in the Sicilian Mafia.

Multiple press accounts since 2015 said Cali had ascended to the top spot in the gang, although he never faced a criminal charge saying so.

His death marks the first killing of a New York City boss in more than 30 years, according to reports. Former Gambino head Paul Castellano was famously killed in 1985 outside a midtown Manhattan steakhouse in a hit ordered by John Gotti, who seized control of the family.
