Brittany Murphy died of community acquired pneumonia and multiple drug intoxication, the Los Angeles County Department of Coroner said in a statement released to Access Hollywood on Thursday. The actress, who died on December 21, 2009, is also listed as having had an iron deficiency and anemia at her time of death.
According to the coroner's office, the death was an accident - but the "injury" occurred because of drug intake. Her pneumonia was listed as the primary cause.
A coroner's office spokesperson further told Access that, according to Brittany's mother, Sharon Murphy, the star had been feeling ill prior to her death and had scheduled a doctor's appointment on a Wednesday or Thursday -- days before her Sunday death. Both her mother and Brittany's husband, Simon Monjack, had been sick a week before Brittany and recovered, but the star's body was unable to fight off the ailment, the spokesperson said.
She was 115 pounds at her time of death.
Sharon and Simon previously stated in interviews that drugs had not been the cause of Brittany's death, with Simon telling The Associated Press that a number of the prescription medications found in the couple's home were his.
A full autopsy report is expected to be released within two weeks.
The former "Clueless" star was 32 years old at the time of her death.
