According to Los Angeles coroner's office, actor Brad Renfro died of heroin overdose.

Renfro’s drug addiction has been public, and when the 25-year old was found dead on January 15 in his Los Angeles home, drug abuse has been the first suspicion.

The Los Angeles County coroner's spokesman, Craig Harvey confirmed the rumors: the cause of Renfro’s death was “acute heroin / morphine intoxication,” the drugs being injected, as the marks on his hands showed. “The final manner of death has been ruled an accident,” Harvey added.

Harvey reported that the actor’s friends told the coroner’s officials that Renfro had been clean during a few weeks before the tragedy. Harvey explained that Renfro might have injected the dose of heroin typical of his days of substance abuse, thus resulting the overdose.

Renfro began earning popularity in 1994, with his role in the legal thriller “The Client.” His career credits also include “Apt Pupil,” “Sleepers” and “Bully.” His only children’s movie was “Tom And Chuck,” a Disney’s production.

But he equally drew media attention with his drug problems and law troubles. In 1998 the Tennessee-native was arrested over cocaine and marijuana possession and he was charged with attempting to steal a yacht in Florida a few years later. After trying to purchase heroin from an undercover officer, he entered a rehabilitation program. At the time of his death, he was still on probation stemming from the incident.
