Ledger pills death an 'enduring agony': Father

Heath Ledger’s grieving father said his son’s death by accidental overdose would be an enduring agony for the family and should be a warning to others not to mix prescription drugs.

His comments came after the New York city medical examiner announced that the 28-year-old 'Brokeback Mountain' star died from the effects of taking six types of painkillers and sedatives.
