Brittany Murphy autopsy says no illegal drug use

brittany-murphy-440.jpgBrittany Murphy's death resulted from a combination of pneumonia, anemia and "elevated" levels of prescription drugs in her system -- but an autopsy report rules out drug abuse as contributing to her death.

The L.A. County coroner's final report on Murphy's Dec. 20 death finds "no history of alcohol or drug abuse." It also notes that she appeared to be "normally muscular and slim but not excessively thin," countering earlier speculation that the "Clueless" and "King of the Hill" actress was dangerously underweight when she died.
