It is expected to take between 10 and 14 days for the autopsy to determine the exact cause of the 28-year-old actor’s death.
A source from the New York Police Department has revealed some additional details regarding the case to the Associated Press.
Six medications were found in Ledger’s apartment, including anti-depressants and sleeping pills that had been prescribed for the star in Europe.
A spokesperson for the police department had also reported that a rolled $20 bill was found near Ledger’s body, which fueled reports that the actor had used cocaine before his death. Test results have now determined that there was no trace of cocaine in the Brokeback Mountain star’s blood.
