NEW YORK -- Officials say actor Philip Seymour Hoffman died from a toxic mix of heroin and other drugs.
A spokeswoman for the New York City medical examiner said Friday that Hoffman died from a mix of heroin, cocaine, amphetamines and benzodiazepines, which are psychoactive drugs such as Librium.
The death was ruled an accident.
Police had been investigating his death as a suspected drug overdose. Law enforcement officials have said Hoffman was found Feb. 2 with a needle in his arm, and tests found heroin in samples from at least 50 packets in his Manhattan apartment.
The 46-year-old star of "Capote" and "The Master" said in interviews last year that he had sought treatment for a heroin problem after 23 years of sobriety.
