Ex-husband of NYC teacher in sex scandal calls gunshots fired into his home ‘attempted murder’

The ex-husband of an NYC teacher accused of having an affair with her principal had six gunshots fired at his Staten Island home three days after The Post broke the scandal, officials confirmed.

The NYPD is investigating the terrifying attack — captured on video — at the Great Kills home of Nicholas Sinodinos, 28, while he was snoozing with his fiancée.

“My life’s been pretty much upside down since then,” he told The Post.

Detectives looked for a link to Sinodinos’ ex-wife Jacqueline, 28, a teacher at PS 21 in Staten Island’s North Shore. Her romantic relationship with Principal Anthony Cosentino was exposed by the Special Commissioner of Investigation for city schools as improper, The Post reported.

Nicholas Sinodinos, an engineer for NYC Health+Hospitals, said his ex-wife and her furious mother, Toni Marie Lucchese Kaminsky, falsely accused him of planting The Post article, which ran on Aug. 10. 

The barrage of bullets came three days later.

At 1:20 am, a male in a white hoodie strolled up to Nicholas’ address, pulled out a handgun and fired six rapid shots at the house, security-camera video obtained by The Post shows. He then turned around and bolted.

Two gunshots pierced the front door, went through the living room and into an adjoining bathroom, leaving bullet holes in three walls, another video showed.

Nicholas and his fiancée were asleep in a bedroom on another floor. Their dog’s barking in the living room woke them up.

“Everyone in the neighborhood heard the shots,” he said.

The  NYPD classified the shooting as “reckless endangerment of property” — a misdemeanor, records show.

“That’s insane,” Sinodinos objected: “This was attempted murder, and should be treated as such.”

In connection with the investigation, the Staten Island District Attorney’s Office sought a subpoena for Jacqueline Sinodinos’ cell-phone records, but a judge denied the request. DA spokesman James Clinton declined to comment on the probe.

“It’s outrageous that the DA was not allowed to subpoena her phone,” Nicholas said. “It could have proved her involvement or cleared her of this crime.”

The day after the shooting, Jacqueline filed a motion in Staten Island family court seeking to revoke her ex-husband’s rights to visit their two children. He is fighting the move.

Meanwhile, Jacqueline was arrested on Aug. 27 on charges of criminal contempt. She is accused of violating an order of protection for Nicholas, who complained that she texted and harassed him. 

She pleaded not guilty, and was released without bail. Her lawyer, John Rapawy, said Friday she claims Nicholas failed to send a document needed to get health insurance for their kids. Nicholas said the kids remain covered under his policy, but she was terminated.

As for the shooting, Rapawy said, “She’s not involved in that at all. And if she had been, she would have been arrested.”

Nicholas Sinodinos filed for divorce last year after Cosentino’s wife blew the whistle on the principal’s relationship with the teacher, he said.

The Special Commissioner of Investigation found Consentino’s conduct possibly violated the city Conflicts of Interest laws because he was the teacher’s boss and recommended her for tenure, a job protection. Romantic relationships between co-workers are forbidden if “a superior has the power to affect … a person’s employment.”

The DOE removed Cosentino from PS 21, but refused to divulge any discipline or new assignment. Jacqueline Sinodinos remains a teacher at the school.
