Actor Brad Renfro, who was found dead in an apartment Jan. 15, died from a heroin overdose, according to a coroner's report. Specifically, the document attributes Renfro's death to "acute heroin/morphine intoxication."

The coroner's office also said that "the final manner of death has been ruled an accident," and that the drugs had been injected. Renfro, who was 25, starred in the 1994 film The Client, and had recently finished shooting a film with Winona Ryder and Billy Bob Thornton.

Renfro had had several run-ins with the law over the years, starting in 1997 when he tried to steal a yacht, and was sentenced to two years probation. By some accounts, the actor said in August that he was trying to get clean and back on track. He had been scheduled for a status check in court on Feb. 27. - Anna Dimond
