Van Is Found; Ties to Killing Are Sought Investigators have located a minivan they believe may have been used to abduct a Brooklyn real estate developer who was killed this month, the police said on Wednesday. The body of the developer, Menachem Stark, 39, was found on Jan. 3 smoldering in a trash container at a gas station in Great Neck, on Long Island. He had been kidnapped the night before as he was leaving his office at 331 Rutledge Street in Williamsburg, Brooklyn, shortly before midnight. Two abductors forced him into a minivan, probably a Dodge Caravan, after a struggle that lasted for several minutes, the police said. An autopsy found that Mr. Stark had died from asphyxiation, indicating that he had probably been suffocated. Police Commissioner William J. Bratton declined to discuss any developments in the case on Wednesday. He told reporters that the case remained "a very active investigation that I'm satisfied is moving along to resolution." But a law enforcement official who spoke on the condition of anonymity said that a van, found in Brooklyn, "fit the description of the vehicle" used to abduct Mr. Stark. The official said that investigators were still trying to conclusively determine whether it was, in fact, the vehicle used in the kidnapping. A person who investigators believed was either the owner or driver of the vehicle has been interviewed, the official said, adding that the person had not been charged in connection with the crime. The police have not publicly identified any suspects in the case, and there has been little progress visible to the public. More than a 1,000 people attended Mr. Stark's funeral, where mourners described him as a pillar of the Hasidic community. But even as he opened new buildings in Williamsburg, Greenpoint and Bushwick, court records indicate that he and a business partner had defaulted on major loans.
