The only explanation the world will ever have for the tragic death of 32-year-old actress Brittany Murphy has been released.

The L.A. coroner ruled it was a combination of pneumonia, iron deficiency anemia, and drug use.

However, despite speculation that Brittany had a problem with cocaine, an accusation vehemently denied by her mother and husband, the drugs found in her system were prescription painkillers for menstrual cramps, and more general remedies like cough syrup, TMZ reports.

Brittany suffered from a rare heart murmur, which was diagnosed in her teens. Her mom told People she believed that condition would ultimately be found responsible for her daughter's premature death.

In the United States, one in 20 people die of pneumonia.
