(February 9, 2008)-- Brad Renfro died of an overdose of heroin and morphine.
But the Los Angeles County Coroner adds that Renfro's death was accidental.
The troubled 25-year-old actor was found dead January 15th.
Renfro got his start as a professional actor in the 1993 movie, "The Client."
But, starting in 1998, his arrests and struggles with drugs and alcohol seemed to overshadow his career.
His lawyer, Richard Kaplan, had said Renfro was working hard on sobriety when he died.
Before he died, Renfro had just finished filming "the Informers" with Winona Ryder, Brandon Routh and Billy Bob Thornton.
