We're still waiting for the results of Philip Seymour Hoffman's autopsy, which will be completed later today, but a search of his home makes the prevailing heroin overdose theory look seriously likely. Authorities found nearly 50 envelopes of what they think is heroin in the apartment, along with more than 20 used syringes in a plastic cup, and several bottles of prescription drugs, law enforcement sources tell CNN.
There were also eight empty bags marked with the street names for various heroin varieties, including "Ace of Spades" and "Ace of Hearts." The NYPD is using those names to hunt for Hoffman's dealer, adds the New York Post, "An internal email went out to all supervisors asking if anyone has had any experience with those brand names of drugs," says a source. Ace of Spades is particularly notorious, the Daily Beast points out, explaining its long history. There have also been a bevy of recent media reports about a deadly tainted heroin variety containing fentanyl, usually sold as "Bud Ice," "Income Tax," or "Theraflu," leadng to speculation that Hoffman might have used it.
