Oscar winning actor Philip Seymour Hoffman was found dead in his Manhattan apartment on Sunday, February 2. He was 46-years-old. Reportedly, the renowned actor died of a heroine overdose.
Law enforcement sources tell us ... they do NOT know specifics about the heroin found in the NYC apartment where Seymour died. There were 10 bags found -- 2 of them empty.
Authorities have been tracking a strain of heroin that has killed dozens of people on the East Coast -- just last month. The heroin is laced with fentanyl, an extremely potent drug prescribed for terminal cancer patients. The strain is 100 times more powerful than morphine ... it sometimes shuts down the respiratory system.
The drug -- sometimes called "Theraflu," "Bud Ice" and "24K" -- has been linked to 5 deaths on Long Island, 22 deaths in Pennsylvania and 19 on Rhode Island -- all in January.
Cops do NOT know if this strain caused Hoffman's death, but they tell us "everything's in play" until they get results from toxicology.
An autopsy to determine the exact cause of death will be conducted today (February 3). Hoffman had battle drug problems before and had reportedly been clean for 23 years before relapsing in 2012.
Hoffman starred in films like Capote, Charlie Wilson's War and Boogie Nights. A big time New York Knicks fans, the NYU grad was often seen court side at games.
