Oscar-winning actor Philip Seymour Hoffman dies of drug overdose

Oscar-winning actor Philip Seymour Hoffman was found dead in his Manhattan apartment Sunday of an apparent drug overdose, law enforcement sources said.

Police said Hoffman, 46, was found on the bathroom floor and pronounced dead at the scene. Investigators found two bags of what is believed to be heroin inside the fourth-floor apartment, law enforcement officials said.

Philip Seymour Hoffman arrives for the Los Angeles premiere of 'The Hunger Games: Catching Fire' at the Nokia Theatre LA Live in Los Angeles, California, on November 18.

"We are devastated by the loss of our beloved Phil and appreciate the outpouring of love and support we have received from everyone. This is a tragic and sudden loss and we ask that you respect our privacy during this time of grieving," Hoffman's family said in a statement. 

Hoffman was last seen alive at 8 p.m. Saturday, a law enforcement official said. He was expected to get his kids on Sunday, but didn't show up, the official said. Playwright David Katz and another person went to the apartment and found him dead, the official said.

A needle was in the actor's left arm, and eight empty glassine-type bags that usually contain heroin were found in the apartment, law enforcement sources told CNN.

The bags were stamped with "Ace of Hearts" and "Ace of Spades" -- street names for the heroin, the sources said.
