Anthony Comello is in custody this weekend over the alleged shooting of crime boss 'Franky Boy' Cali.
Comello from his Brick, New Jersey, is expected to face murder charges over the killing after being apprehended by authorities.
However, in a new twist, it has emerged that the murder might have been the result of a personal dispute rather than a 'mob hit.'
It is now being reported that he could have killed the Gambino mob boss because he refused to allow him to date his niece.
A non-organized crime issue between the killer and Cali is an "angle that is being explored," a high-ranking NYPD source has revealed.
And separate sources are alleging that the killing "appears" to be unrelated to any Mafia feud.
New Jersey Regional Task Force apprehended Comello just three days after crime boss 'Franky Boy' Cali was murdered outside his Staten Island home.
Comello, originally from Staten Island, is believed to have no ties to the mob and could have acted alone.
It is understood that the victim might have known his killer and that the crime could gave been captured on CCTV cameras at the house.
There have been reports that the killer hit Cali's SUV on purpose as it was parked in his driveway to lure hi outside.
The mob boss was then gunned down at point-blank range before the killer sped away from the scene.
The killing marked the city's first murder of a sitting mob boss since the December 1985 hit on Gambino boss Paul Castellano, who lived in the same Todt Hill neighborhood where Cali was murdered.
Cali, 53, rose quickly through the ranks of the Gambino mob family after arriving in New York, moving up to the rank of capo before the age of 40.
He was bumped promoted to acting boss in 2015 after serving on a panel that led the once-mighty crime syndicate named for the late, legendary Mafioso Carlo Gambino.
Cali served16 months for his part an extortion scheme before his release in April 2009. His wife is the niece of a Gambino capo, while his brother and brother-in-law are reputed Gambino soldiers.
Police were worried that his shooting could spark a bloody war between rival gang families.
