Brittany Murphy Autopsy Results Inconclusive, Drug Tests Ordered

The final results of Brittany Murphy’s autopsy could take six weeks after the L.A. Coroner’s office was unable to determine her cause of death.

The Coroner’s office said in a statement that an autopsy undertaken today did not reveal conclusive reasons for Brittany Murphy’s death. In echoes of the Michael Jackson autopsy results delay, the Coroners office has ordered neurological and toxicology tests, which will at the least take weeks, and possibly as long as 6 weeks.

The failure to determine a cause of death at the initial autopsy leads strength to speculation that Murphy’s cause of death may have been due to a drug overdose.

Los Angeles Police are currently investigating the drug overdose theory, and are not ruling out foul play with homicide detectives also part of the investigation.
