                                    Actor Heath Ledger died of an accidental overdose of sleeping pills, painkillers, and anti-anxiety medication, the New York City Medical Examiner's Office ruled today. OxyContin, Valium, Xanax, Restoril, Unisom, and ibuprofen combined to result in a lethal "acute intoxication," an ME spokeswoman told the AP.
