LEDGER AUTOPSY 'INCONCLUSIVE'

LATEST: An autopsy on the body of tragic actor HEATH LEDGER has failed to reveal how the star died.

The Brokeback Mountain star, 28, was found dead in the bedroom of his New York apartment on Tuesday afternoon (22Jan08).

Police believe his death is drug-related, as sleeping pills were found strewn around his home, but it has also been reported that the star was suffering from pneumonia at the time.

And now U.S. medical examiners, who carried out an autopsy on Ledger's body on Wednesday (23Jan08), have announced that their findings were inconclusive.

Officials will now have to wait for the results of a series of toxicology tests which may hold further clues into what caused the 28-year-old's death. A spokesman for the medical examiner assigned to the case insists it may take up to 10 days to conclude their investigation.
