NEW YORK - (AP) - Results could be released today on the autopsy of actor Philip Seymour Hoffman, who was found dead in his New York City apartment Sunday, with a needle in his arm.

Officials say packets of heroin were found near the 46-year-old's body and police suspect he died of an overdose.

Investigators are wondering if Hoffman's death could be linked to a potent blend of heroin and synthetic morphine.

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. Eastern time.
