TMZ reports that multiple sources say her condition was"preventable". The L.A. County Coroner also believes her condition was treatable but she did not receive the proper medical care in time. The main cause of her death was her pneumonia and severe anemia, with the multiple drugs found in her system "pushing her over the edge". The drugs found in her system include prescription as well as over-the-counter medications. One of the prescription drugs found were pre-menstrual medication for cramps, as well as over-the-counter cough syrup.More at the examiner.
