Before his death, Hoffman's addiction had seemed to be under control.

The 46-year-old Oscar winner was found on the bathroom floor with a syringe in his left arm and bags of what appears to be heroin inside the apartment. Those items are being tested. Police will only say the investigation is continuing. According to an early report by CNN, approximately fifty bags of the suspicious substance were found on the scene, along with numerous syringes, addiction treatment medication, blood pressure medication, and a muscle relaxant.

Various drug paraphernalia were found at the scene along with mass quantities of heroin.

The Associated Press quoted two separate sources in law enforcement as saying that the bags were stamped with the ace of hearts symbol, and others with the words "Ace of Spades" and that symbol. In addition, the substance in at least a few of the packets has been confirmed to be heroin. The family released a statement via Hoffman's publicist, Karen Samfilippo, on Sunday: "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. Please keep Phil in your thoughts and prayers."
