According to multiple reports, on Tuesday night law-enforcement officials busted four people believed to have supplied the heroin that killed the 46-year-old actor.
The New York Post reports that police arrested Robert Vineberg, 57, Thomas Kushman, 48, and charged them with felony drug possession. Max Rosenblum and Juliana Luchkiw, both 22, also were arrested and charged with misdemeanor drug possession.
Vineberg, a musician who goes by the name Robert Aaron and has accompanied Wyclef Jean and Tom Jones, replied with a sheepish "No, I did not," when asked if he had sold Hoffman heroin, according to the Post.
The four were reportedly arrested in a Chinatown apartment on Mott Street, according to the Daily News, after police received a tip that the drugs found in Hoffman's apartment came from the Chinatown building. Police reportedly found 350 glassine envelopes containing a substance believed to be heroin.
On Sunday shortly after 11:30 a.m., Hoffman's body was found lying on the bathroom floor of his New York City apartment, the victim of an apparent drug overdose. A police source confirmed to PEOPLE that Hoffman had a syringe in his arm and that two clear envelopes of what appeared to be heroin were found nearby. Eight empty envelopes also were discovered in the apartment.
A private funeral service for the actor is scheduled to take place Sunday in New York City, and plans are underway for a memorial service, also in New York, later this month.
