Philip Seymour Hoffman described battling his "demons" in two diaries found in the West Village apartment where he died with a needle in his arm, police said Tuesday, according to the New York Daily News.
Both reportedly chronicled Hoffman's descent into heroin abuse and his attempts to control his addiction by attending Narcotics Anonymous meetings, according to NBC News. The 46-year-old Oscar-winner, who was found dead on Super Bowl Sunday, apparently wrote at least some of the entries while he was in rehab, NBC reported.
Hoffman reportedly became addicted to drugs in college, but remained clean for more than 20 years. He fell off the wagon last year and went into rehab for 10 days. After getting out, he relapsed, drinking heavily and using heroin, sources told the Daily News.
While an autopsy was inconclusive, police say they believe Hoffman died of a heroin overdose because they found 70 baggies of heroin in his apartment.
Hoffman was buried Friday after a funeral attended by some of the biggest stars in Hollywood.
He and longtime girlfriend Mimi O'Donnell had three children.
