London, Feb 5 (ANI): A Los Angeles coroner has revealed that actress Brittany Murphy died due to pneumonia.

Spokesman Craig Harvey also said that iron-deficiency anaemia and "multiple drug intoxication" were secondary factors in her death.

While the drugs were all prescription medicines, more details are due in two weeks when a complete report is ready, reports the BBC.

The Clueless star passed away after collapsing at home on January 20. The coroner ruled the death was accidental.

Murphy's husband, Simon Monjack and mother, Sharon Murphy, said the actress had been experiencing flu-like symptoms in the days before she died.

Monjack said his wife had several prescriptions, including one for an anti-seizure drug, but did not abuse her medication. (ANI)
