Los Angeles coroner spokesman Craig Harvey announced yesterday that Brittany Murphy‘s main cause of death was pneumonia. However, he added that iron deficiency anemia and prescription drugs also played a role. The death was ruled accidental. Harvey wouldn’t specify what types of drugs were involved but said they were all prescriptions. Details about the drugs will be released in several weeks when a complete report is done. Murphy died at the age of 32 on December 20 after collapsing in her bathroom. Her husband, Simon Monjack, and her mother, Sharon Murphy, who were home with her at the time, told investigators Brittany had been experiencing flu-like symptoms for several days before she died. Monjack told The Associated Press last month that his wife was taking Robitussin at the time, as well as several prescriptions, but in moderation.
