A search of the home of Philip Seymour Hoffman home turned up used syringes and approximately 50 bags of heroin, according to law enforcement officials.
Police also found drug paraphernalia and prescription drugs. An autopsy is expected to be performed on Monday.
The Oscar-winning actor was found dead in his West Village apartment on Sunday morning with a hypodermic needle in his arm. He was 46.
Hoffman, who won the best actor Oscar for “Capote” in 2005, most recently appeared at the Sundance Film Festival this month to promote his new films “God’s Pocket” and Anton Corbijn’s “A Most Wanted Man.”
He was also shooting the “Hunger Games” follow-ups “Mockingjay Part 1″ and “Part 2″ in Atlanta, reprising his role as Plutarch Heavensbee from “The Hunger Games: Catching Fire.”
