The New York medical examiner's office has reported that Heath Ledger's death was the result of an accidental overdose.
Autopsy results showed that a lethal mixture of prescription medications were responsible for the young actor's demise. Present in his system at the time of his death were oxycodone, hydrocodone, diazepam, temazepam, alprazolam and doxylamine.
Translation: hydrocodone and oxycodone are both basically types of Vicodin (painkillers); diazepam, temazepam and alprazolam are all types of Valium (anti-anxiety/sleep meds); and doxylamine is the active ingredient found in Nyquil and over-the-counter sleep aids like Unisom.
It appears as though Ledger took none of the individual medications to excess, but rather the combination proved unwittingly fatal.
Ledger's family returned home to Australia yesterday for his funeral.
