The New York Chief Medical Examiner's Office is expected to release the results of Heath Ledger's autopsy tomorrow (Tuesday, February 5).
The office is required by law to give cause and manner of death. No other details will be released.Ledger was found dead, surrounded by pills but no illegal drugs were found on the premises.
If the actor is found to have died of drugs not found in his apartment room, then an investigation will be taken.
The actor was found by a housekeeper and his masseuse, but there was a lapse of time between finding the body and calling the police.
It is known that the housekeeper made a number of calls to Mary-Kate Olsen before alerting authorities. Mary-Kate was the owner of the apartment and a friend of Ledger.
While no foul play is expected, the cause of death may raise more questions than it answers.
If the toxicity reports show that illegal drugs were in the body, further questions may be asked of the housekeeper, the masseuse and Mary-Kate.
Ledger's body is on its way back to Australia. His family departed LAX on Monday night (US time) and will arrive in Melbourne tomorrow morning before flying on to Perth for the funeral.
Ledger will be buried next to his grandparents in the family plot at Karrakatta cemetery in Perth.
