After Murphy, 32, was found dead Sunday morning from cardiac arrest, the LAPD and Coroner launched an investigation quoting "other reasons" that couldn't be discussed.

According to RadarOnline.com and other sources, the police are focusing on the possibility of a
prescription drug overdose and one leading pathologist told The Early Show it had to be a lethal combination of prescription drugs that caused the death of Brittany Murphy.

"It's possible, certainly", Dr. Cyril Wecht said of the possibility Murphy died from natural causes to The Early Show on Tuesday, "And usually, it will be some kind of a congenital heart condition. But in most of those cases, the patient will be aware that there is some heart problem," Dr. Wecht said.

Adding, "When you have a 32-year-old person dying suddenly, and especially a celebrity in Los Angeles, you can place your bet down that it's going prove to be a case of acute combined drug toxicity. And I bet you that this young lady tragically died in the same way that Michael Jackson did, and Anna Nicole Smith, and her son, Daniel Smith, and Heath Ledger -- a combination of drugs that had been prescribed for her, prescribed for her husband, for her mother, in some fictitious names, probably by doctors who are very, very quick to make available anything that celebrities want, sometimes using knowingly fictitious names."
