Authorities are investigating new allegations linking retired FBI agent R. Lindley DeVecchio to another gangland-style slaying carried out by DeVecchio’s top echelon informant, Colombo capo Gregory Scarpa. 

This killing is a little different, however, than the mob rubouts already charged to the gangster and his G-man associate. It involves a former abortion doctor who was shot to death in Queens on December 3, 1980, Gang Land has learned. 

Sources say the Brooklyn District Attorney’s office has received information that DeVecchio allegedly warned Scarpa that the ex-doctor was cooperating in a probe of the mobster.

The murder took place the same year DeVecchio officially recruited Scarpa – who reportedly broke off an earlier 13-year stint as an FBI snitch in 1975 when agents balked at forking over a $1500 payment. DeVecchio’s soft-sell approach to the two-timing gangster was that he would be paid well and would have to answer only to DeVecchio. 

Shortly after he signed up Scarpa, DeVecchio allegedly alerted his murderous informer that Eliezer Shkolnik, 52, whose medical license had been revoked in

1976, was cooperating with an Internal Revenue Service probe that was looking into Scarpa’s activities, sources said.

Sources say state prosecutors obtained the latest allegation shortly after Brooklyn District Attorney Charles Hynes announced that a grand jury had charged the retired agent with four murders, beginning in 1984 with the slaying of Mary Bari, 31, (right) onetime mistress of a top Colombo family mobster.

The Shkolnik murder “isn’t the only new allegation to surface” in recent weeks, said one investigative source, declining to elaborate.

A focal point of the current investigation into Shkolnik’s murder, sources say, is a former beauty queen – Lili Dajani, Miss Israel of 1960 – who was Shkolnik’s business partner and was romantically linked to both him and Scarpa at the time of the killing. 

During the 1970s, Dajani, a semi-finalist in the 1960 Miss International Beauty Pageant, worked as a nurse-receptionist at a Manhattan women’s center that Shkolnik ran both before and after he lost his medical license. During that period, sources say, she and the married Shkolnik became lovers, a relationship  that contributed to a messy divorce that ended with the ex-doctor changing the

name of the women’s center, placing it in Dajani’s name, and remaining on as the center’s administrator.

In 1975, Scarpa, (left) despite being married to one woman and living with another – longtime companion Linda Schiro – married Dajani in Las Vegas, according to a 1996 article in the New Yorker Magazine by reporter-author Frederick Dannen.

Sources say that Dajani and Scarpa also had a business relationship. 

“She had invested money with Scarpa. It was something that was designed (by Scarpa) to help Linda,” said one investigative source, adding that Dajani was “upset with Scarpa” about her losses. 

Sources say that Scarpa and crew member Joseph (Joe Brewster) DeDomenico – whom Scarpa would murder seven years later, allegedly with DeVecchio’s help – and a third cohort gunned down Shkolnik in the vestibule of his parents’ Forest Hill apartment building at 7:30 in the morning.

The killers shot Shkolnik in the head, leaving behind more than $1500 in cash he had in his pockets and expensive gold jewelry he was wearing.

Witnesses told police they saw two men run out of the building moments after the

shooting, and speed away in a blue getaway car driven by a waiting accomplice. The murder is listed as unsolved, police say.

Dajani (right) could not be reached by Gang Land. Prosecutors Michael Vecchione and Noel Downey declined to comment about their inquiry into the Shkolnik killing. 

Mark Bederow, an attorney for DeVecchio, labeled the new allegations as “pure fantasy. We said it before, and we will say it again: Lin is innocent. The idea that Lin DeVecchio conspired with Greg Scarpa Sr. to murder anyone is ludicrous. It didn’t happen.” 

Shkolnik’s son Hunter, told Gang Land that a day after DeVecchio was indicted, an anonymous caller contacted him at his law office – he is an attorney in Manhattan – and implicated the retired agent in his father’s murder.

“It was a shock,” said Hunter Shkolnik, noting that the caller referred to him by name when he answered the phone, stating: “Hunter, this may be of interest to you. It’s about that FBI agent and your father’s death. He had something to do with it.” 

Hunter Shkolnik had been away at college at the time his father was killed, but had seen him a few days earlier when the younger Shkolnik returned home for the Thanksgiving Day weekend. 

By then, Shkolnik recalled, his father’s relationship with Dajani had soured and

he was living with his parents. But his father expressed confidence that his earnings would soon increase to prior levels, telling his son: “I’m finally going to get the business back.” 

A couple of months after the murder, Shkolnik recalled, detectives determined that they were unlikely to be able to solve the case. “They had hit a wall,” he said. And they strongly suggested that the Shkolnik family not try to retrieve his father’s business from Dajani for their own sake, advice the family accepted. 

“That’s what they said to us. ‘Don’t do it. You don’t want to get involved. It’s probably what got your father killed.’ Now that I’m looking back at the things that were said to us at the time…. In retrospect, they may have been right,” he said. 

Meanwhile, the pending charges against DeVecchio – which include the 1990 murder of Patrick Porco and the 1992 slaying of Lorenzo (Larry) Lampesi – are on hold to permit Brooklyn Federal Judge Frederic Block (left) to determine whether the case should be tried in state or federal court. 

Citing statutes that permit state indictments against federal officers to be adjudicated in federal court if the allegations stem from their jobs, DeVecchio’s lawyers have asked that the case be removed to federal court and tried there.

Judge Block has given the Brooklyn District Attorney’s office until May 25 to submit court papers opposing the removal. DeVecchio’s attorneys have until June 23 for their final response.
