The New York City chief medical examiner’s office has released Philip Seymour Hoffman’s autopsy report.

They have ruled that the actor, who was 46, died of acute mixed drug intoxication, including heroin, cocaine, benzodiazepines and amphetamine. His death was ruled by the coroner as an accident.

As previously reported, Hoffman’s body was found in his New York City apartment in early February with numerous bags of heroin and a needle still in his arm.

Hoffman had previous brushes with drug abuse in the past and spoke about them openly over the years.

Said his family in a statement after his passing, “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.”

Hoffman was in the midst of filming his role as Plutarch Heavensbee for The Hunger Games: Mockingjay. After his death, reports indicated that the actor had filmed the majority of the scenes he was needed for but still had a few days of filming left. Lionsgate will not recast the role but may have to digitally recreate him in a couple of shots.

Lionsgate said in a statement after his passing, ““Philip Seymour Hoffman was a singular talent and one of the most gifted actors of our generation. We’re very fortunate that he graced our Hunger Games family. Losing him in his prime is a tragedy, and we send our deepest condolences to Philip’s family.”

The actor had gone through rehab last May to prevent what he believed was a forthcoming relapse.

Hoffman is survived by his longtime partner Mimi and their three children.
