The preliminary autopsy on Philip Seymour Hoffman is expected Monday.
But authorities say all signs point to a drug overdose. Investigators found roughly 50 bags of heroin, used syringes and other drug paraphernalia inside Hoffman's West Village home.
The discovery marks a tragic fall for one of the greatest actors of his generation.
“I'm just in shock. I feel so. So horrified... In a way... It's bad to know how he died...because I mean he must have been in a lot of pain.”
Drug addiction had haunted Hoffman for years. A heroin user in college, then going sober. But after two decades, he was back in rehab last year.
Hoffman's death is the latest tragedy to hit Hollywood involving drugs.
Last year, it was the young Glee actor Corey Monteith. He overdosed on a mix of heroin and alcohol.
A year earlier, Whitney Houston found dead in a hotel bathroom with cocainein her blood.
And in 2008, in an apartment not far from Hoffman's, Heath Ledger succumbed to a cocktail of prescription drugs.
“With the death of Hoffman we really see how drugs are really pervasive in Hollywood and it really is sort of epidemic in Hollywood, “said David Caplan.
Hoffman's legacy will live on in his award-winning films and in several new releases due out this year.
“It actually keeps the gratitude you know if you just go to what you need to go to, the gratitude stays instead of the cynical thing that will start to wear on you.”
Hoffman who was just 46 is survived by a long time girlfriend and three children. The family in a statement asked for privacy saying they are devastated by the loss.
