NEW YORK (AP) _ Investigators found human body parts amid four tons of medical waste near a trash hauling company and said they suspected a link with organized crime, according to a report today.

Authorities are trying to determine whether the body parts - arms, legs and part of a torso - discovered in September belonged to an mob execution victim or victims, and if so, whether other victims were disposed of the same way.

''There were no fingers or other identifiable parts,'' a law enforcement source told the Daily News.

City and federal investigators got and executed a search warrant for the company, National-Stage Carting, after a tip from a mob informant, the report said.

They found the parts in a refrigerated trailer full of medical waste, which was packed in more than 50 boxes, parked on a side street near the company in the Brooklyn borough.

A spokesman for the city Department of Investigation, Ron Davis, confirmed that the trailer contained body parts.

The newspaper said the tractor-trailer was registered to Rosendale Haulage, a Florida company with ties to Anthony Vulpis.

Vulpis, National-Stage owner Angelo Paccione and a developer, Fred Weiss, were indicted last month on federal charges of racketeering, conspiracy and mail fraud for their operation of a dump that allegedly stored infectious medical waste.

Vulpis' nephew, Anthony Senter, was convicted recently of racketeering and a civil rights conspiracy. During his 17-month trial, witnesses said he disposed of two mob execution victims who were chopped up and hauled in garbage trucks.

The tipster identified Senter as the man who killed the victim whose body parts were found at National-Stage, the newspaper said.

''The two cases have nothing to do with each other,'' said Ben Brafman, the attorney for Vulpis and Senter. ''It is stretching the truth to connect them.''

Paccione is a major player in a mob carting cartel controlled by the Gambino crime family, investigators told the Daily News.

He has said he is a businessman with no organized crime connections and that nothing improper happened at the dump.

National-Stage has no license for collecting medical waste, a state Health Department spokesman, Jerry Wolf, told the Daily News.
