NEW YORK - Tom Petty died last year because of an accidental drug overdose that his family said occurred on the same day he found out his hip was broken after performing dozens of shows with a less serious injury.

His wife and daughter released the results of Petty's autopsy via a statement Saturday on his Facebook page, moments before coroner's officials in Los Angeles released their findings and the rocker's full autopsy report. Dana and Adria Petty say they got the results from the coroner's office earlier in the day that the overdose was due to a variety of medications.

The coroner's findings showed Petty had a mix of prescription painkillers, sedatives and an antidepressant. Among the medications found in his system were fentanyl and oxycodone. An accidental overdose of fentanyl was also determined to have killed Prince in April 2016.

Petty suffered from emphysema, a fractured hip and knee problems that caused him pain, the family said, but he was still committed to touring.

He had just wrapped up a tour a few days before he died in October at age 66.

"On the day he died he was informed his hip had graduated to a full on break and it is our feeling that the pain was simply unbearable and was the cause for his over use of medication," his family's statement said, adding that he performed more than 50 concerts with a fractured hip.

The family said Petty had been prescribed various pain medications for his multitude of issues, including fentanyl patches, and "we feel confident that this was, as the coroner found, an unfortunate accident." - AP
