Tom Petty died from massive accidental drug overdose

The autopsy results of '80s rock legend Tom Petty – who died on October 2 last year - are in, and they show the singer died from an accidental drug overdose as a result of taking a variety of medications.

The LA County Coroner says a number of Tom's organs failed due to “mixed drug toxicity,” according to TMZ.

The autopsy report says when paramedics arrived he was in full cardiac arrest, but CPR revived him — but on the way to the hospital he lost pulse for 20 minutes. He went into cardiac arrest a second time in the hospital and died 21 hours after being admitted.

The autopsy report shows the singer was on several pain meds. The reason doctors prescribed the meds was because of a number of medical problems, including emphysema, knee problems and a fractured hip. The family says the linchpin to Tom's demise was the fractured hip.  He insisted on touring for 53 concert dates with the condition, which worsened over time and caused him to take the meds. On the date he died he was told the hip had graduated to a full-on break that made the pain unbearable and may have caused the overuse of meds.
