Philip Seymour Hoffman's death appears to be heroin related, according to investigators, though the cause of the actor's death has not been made official.
Officials confirmed Philip Seymour Hoffman dead Sunday at his New York apartment and a deadly strain of the drug as one of the operating theories.
To be clear, law enforcement sources do not know any specifics about the heroin found in the Manhattan apartment where Seymour died at the age of 46.
There were 10 bags found of the drug, however, eight of them empty.
Here's where it gets particularly interesting (and very scary): Authorities have been tracking a new strain of heroin that has killed dozens on the East Coast.
Already in 2014, the heroin laced with fentanyl - an extremely potent drug prescribed for terminal cancer patients - has been making the deadly rounds.
The strain is 100 times more powerful than morphine, according TMZ, and is so potent that it sometimes shuts down the respiratory system altogether.
Sometimes called "Theraflu," "Bud Ice" and "24K," the heroin strain has been linked to five deaths on Long Island, 22 in Pennsylvania and 19 on Rhode Island.
That's all in January 2014. It's become a major thing of late.
We reiterate that police are not saying this is what caused Hoffman's death, but officials say "everything's in play" until they get results from toxicology.
We'll have those results for you when we know them. R.I.P.
