Despite the Mafia rule that only full Italians could be "made", or officially inducted into the organization, Rosenberg reportedly believed that his earning abilities and willingness to murder might eventually lead to his becoming a member of Cosa Nostra.

Henry Borelli, who had become involved with the crew shortly after Chris was shot, suggested that he use a woman friend of his to bait Andrei to a location where he could be abducted and then dealt with discreetly.

Arriving at the woman's apartment complex expecting to take her out on a date, Andrei was forcefully abducted by Rosenberg, Borelli, Testa and Senter and taken to the meat department of a grocery store, where DeMeo was waiting.

Katz was stabbed multiple times in the heart with a butcher knife, presumably by Rosenberg in revenge for the shooting that had ruined his face.

The nephew of Demeo's superior Anthony Gaggi within the Gambino Family, Dominick Montiglio, later testified that he learned of the murder from Rosenberg shortly after it happened.

He also testified that Rosenberg claimed Katz's murder had driven DeMeo and his crew to decide that any future conflicts would be settled in a similar manner of dismemberment to make the victim disappear.

Dominick Montiglio, who visited DeMeo frequently to pick up payments for Anthony Gaggi, said in an interview that if the crew didn't kill at least three people a week, they would be depressed.

These same witnesses also claim that Rosenberg usually did the stabbings, as well as the subsequent dismembering of the body, in his boxer shorts or underwear in order to avoid staining the expensive clothes he wore.

When Rosenberg demanded payment shortly after giving him the drugs to sell, Guelli claimed someone had robbed his house and stolen the product.

Another man was found shot to death and dumped into the trunk of a car allegedly after attempting to rip Rosenberg off in a marijuana deal.

In 1979 he visited Florida to set up a cocaine deal with a loanshark customer of Roy DeMeo's who had entered the drug business in an attempt to pay off his debts.

That same night Rosenberg visited a hospital with gunshot wounds on his hand and on the side of his head, suggesting that the group may have tried to fight back before being killed.

When the mysterious "El Negro" did not receive a phone call from his cousin or girlfriend that night to ensure that the sale had been completed, he contacted Charles Padnick's son Jamie in an attempt to get more information.

Jamie Padnick flew to New York shortly after and disappeared as well after being murdered and dismembered by Rosenberg and his fellow crew members.

Dominick Montiglio, the nephew of DeMeo's superior Anthony Gaggi, became a government witness in 1983 and claims that he was in charge of delivering messages back and forth between the Cubans' contact in New York and the Gambinos.

After a period of inaction on the part of the Gambinos, the Cuban drug lord sent a group of enforcers to New York and threatened violence if Rosenberg was not murdered soon.

Rosenberg's body was then placed in his car, which was driven and left parked on a street near the Gateway National Recreation Area in New York City.

Crew member Frederick DiNome then drove by the vehicle while Henry Borelli raked it with machine gun fire, to ensure the murder was a blatant enough assassination to guarantee that it would be mentioned in the local newspaper.

At the trial in 1988, testimony was given by Dominick Montiglio and Vito Arena linking the remnants of the DeMeo crew with Rosenberg's murder.

In 1989 the defendants were convicted of all charges and Joseph Testa and Anthony Senter, the only core DeMeo Crew members who had not been murdered or already imprisoned, were sentenced to life in prison.
