The results of an autopsy proved inconclusive in determining a cause of death for rapper Heavy D, who died suddenly Nov. 8 outside of his Beverly Hills home. Toxicology reports are still pending, though a spokesman for the L.A. County coroner said last week that no illegal drugs were found in Heavy D's house. Authorities did discover a prescription drug that he was taking to treat a cough that might have been pneumonia. The toxicology report could take several weeks to return a result. Foul play is not suspected. [via The Hollywood Reporter]
