The autopsy of Oscar winner Philip Seymour Hoffman, who was found dead on Sunday of an apparent drug overdose, will be conducted by the New York medical examiner's office today, according to medical examiner spokeswoman Julie Bolcer.
The actor, 46, was found on the bathroom floor with a syringe in his left arm and bags of what appear to be heroin inside the apartment. Those items are being tested. Police will only say the investigation is continuing.
NBC News and CNN reported that authorities at the scene found roughly 50 bags of heroin, numerous syringes, addiction treatment medication, blood pressure medication, and a muscle relaxant.
The actor was last seen alive on Saturday night. Hoffman's body was removed from his apartment Sunday night.
His friend, actress Kristen Johnston, posted a heartfelt tribute to the actor. The two studied acting together.
"Thank you for all your kind words about Phil. Sadly, after being sober for years & years, he relapsed & has been grappling with his addiction for last few yrs. I wish I could say I was shocked, but all I feel is a mixture of terrible grief, sad resignation & a powerful rage. Many, many people die from this disease. Like them, Phil didn't want to die. He fought hard to get clean. He had a family he loved, many friends who adored him & a career he was proud of," she wrote.
"But addiction doesn't care about that. I feel that part of the problem might have been his shyness & his deep need for privacy, which prevented him from being able to be open with others about it. Whatever the reason, his brilliant work will live on. From my very 1st acting class at NYU to the last time I saw him about a year ago, he was always the sweetest, shyest, loveliest man."
Hoffman has three children — Cooper, 10, Tallulah 7, and Willa, 5 — with costume designer Mimi O'Donnell.
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."
Hoffman won the best-actor Oscar for Capote in 2006. He was nominated for supporting-actor Oscars for his roles in The Master, Doubt and Charlie Wilson's War.
Broadway theaters will dim their marquee lights Wednesday night in memory of Hoffman.
The Broadway League said Monday the lights will be dimmed for one minute starting at 7:45 p.m. ET.
Hoffman made his Broadway debut in Sam Shepard's True West with John C. Reillyin 2000 and followed it up three years later with Eugene O'Neill's Long Day's Journey Into Night with Brian Dennehy and Vanessa Redgrave. In 2012, he played a powerfulWilly Loman in Death of a Salesman by Arthur Miller under the direction of Mike Nichols. Each time he earned a Tony nod.
