Crooked ex-LI cop who moonlighted as a Bonanno solider helped fuel mini-mob war with rival Genovese

Mob justice is best served cold.

A crooked Nassau County police detective moonlighting as a Bonanno soldier helped fuel a mini-mob war on Long Island — choosing “the crime family over the public he swore to protect,” a court heard Tuesday.

Ex-Det. Hector Rosario conspired to target rival Genovese mafiosos in the feud that spilled out after the organized crime clans struck an unusual agreement to split the proceeds of a gelato shop’s backroom gambling den, according to the feds.

But peace didn’t last and Rosario “sold himself” to the Bonnanos — even staging a fake police raid at a Genovese backroom gambling den, Brooklyn federal prosecutors said in opening remarks at the alleged dirty cop’s trial.

“He and other men barged in acting like actual police officers, broke a gambling machine and sent a message,” Anna Karamigios, assistant US attorney for the Eastern District, told jurors.

The Bonannos and Genovese – two of the Five Families in the American mafia – generally kept to their separate spheres during the 1980s and into the early 2000s, said a long-time mob investigator.

“There were no beefs and no sit-downs,” the investigator said. “As far as business, there were no major schemes that they worked on together.

“Back then, ‘The Chin’ (Vincent Gigante), the head of the Genovese family, did not respect (Bonanno boss) Joe Messina, so he would have nothing to do with him.”

Now, the expected two-week trial against Rosario — who is charged with obstructing a grand jury probe into racketeering and lying to the FBI — promises to expose secrets of New York’s alive-and-well mob underworld.

Jurors spent the trial’s first day of testimony Tuesday being introduced to a Who’s-Who of wiseguys, from Sal Russo to “Sal the Shoemaker.”

They also learned about a constellation of illegal gambling operations — leading to a sweeping bust in 2022 that rounded up eight alleged mobsters and Rosario, who’s accused of being on the take for $1,500 a month.

“He chose the crime family over the public he swore to protect,” Karamigios said.

The then-detective’s nefarious side gig as Bonanno stooge came in handy for the family sometime around 2012, according to trial testimony.

A former Bonanno soldier — Damiano Zummo, 51 — testified that the family had entered into an arrangement with their Genovese brethren to share profits from Gran Caffe, a gelato shop in Lynbrook that doubled as a covert casino.

The shop had two card tables in the back, along with poker machines in a small room, Zummo, the first witness to testify, said.

The owner originally split profits 50-50 with a Genovese family member, but that arrangement ended when the mobster got sent to prison, Zummo testified.

The Bonannos got involved after the owner sought protection after being beaten up, Zummo said. They reached an uneasy agreement for a 25% each share of profits, effectively making it a joint Bonanno-Genovese mob venture, he said.

The understanding between mob families was that they could not operate competing gambling parlors within a 5-mile radius, Zummo said.

But tensions boiled over when a down-on-his-luck gambler opted to stop patronizing the gelato shop in favor of gambling at Sal’s Shoe Repairs, which was run by Salvatore “Sal the Shoemaker” Rubino, a Genovese mobster, Zummo testified.

The move resulted in the Bonanno family — which was pulling in $10,000 — “losing money,” Zummo said.

He said Sal Russo, a Bonanno, wanted to “intimidate” the Genovese by using Rosario.

“Russo came up with the idea of a fake raid and I was all for it,” Zummo testified.

“For Hector to go in there, to Sal’s Shoe Repairs, and intimidate them in hopes they close down.”

Sal’s Shoe Repair had a card table in the back room with three or four gambling machines, Zummo said.

The fake raid of the shoe repair gambling den didn’t result in any arrests or citations, prosecutors said.

Zummo said that Rosario carried out an aborted raid at a coffee shop with a gambling den in Valley Stream owned by the Gambino family, because it was less than a mile from “Soccer Club,” a Bonanno-operated parlor owned by Sal Russo.

But the would-be raid went south when Rosario and a crew of a few guys weren’t able to get inside the gambling den, Zummo said.

The reason: it had a buzzer and they weren’t allowed inside, Zummo testified.

Rosario liked “again, and again” when pressed by the FBI during interviews in 2020, claiming he didn’t know anything about gambling dens, prosecutors said.

He also pulled information of a rival mob member from a law enforcement database and gave it to the Bonanno family, according to prosecutors.

The Bonanno family paid Rosario $1,500 per month during the time of the raids, which went on for a “few months,” according to Zummo.

Zummo testified that Rosario also tipped him that he was under investigation and to “stay off the phone” because “the feds are listening.”

He testified that he considered Rosario to be a “street guy.”

“Street guy means he’d break the law if he had to,” he said.

Zummo was arrested in 2017 alongside Russo in a drug-trafficking scheme that involved a $40,000 sale of cocaine in a Manhattan gelato shop.

Both are cooperating with the feds in the case.

Rosario’s defense attorney Lou Freeman told jurors that the former cop had made a false statement to authorities, but it was about a marijuana grow house in Queens that wasn’t material to the case.

He also argued that witnesses who are convicted of racketeering, distribution of cocaine and other serious crimes would be testifying against Rosario, who has pleaded not guilty and is out on bail.

“Each of these witnesses were in organized crime,” he said.

Sal Russo, who was once a “close friend” of Rosario’s, had put the former Nassau cop on the feds’ radar in hopes for a more lenient sentence, Freeman said.

“You will hear Sal Russo made up information about Hector Rosario to get one more notch on his belt because more notches on a cooperating witness’s belt mean less jail time,” Freeman said.

The feds confirmed they will be calling three cooperating witnesses during the trial, which resumes Wednesday.
