The Los Angeles County Coroner has released its findings as to the cause of Tom Petty’s death. Their conclusion: a massive and accidental overdose of different medications, including opioids.

Tom Petty, the chart-topping singer and songwriter, died in October from an accidental drug overdose as a result of mixing medications that included opioids, the medical examiner-coroner for the county of Los Angeles announced on Friday, ending the mystery surrounding his sudden death last year.

The coroner, Jonathan Lucas, said that Mr. Petty’s system showed traces of the drugs fentanyl, oxycodone, temazepam, alprazolam, citalopram, acetyl fentanyl and despropionyl fentanyl.

Barely a week after Mr. Petty, 66, had concluded a tour with his band, the Heartbreakers, with two shows at the Hollywood Bowl, representatives said the singer had suffered cardiac arrest at his home in Malibu, Calif. on Oct. 2. But Mr. Petty’s official death certificate, released about a week later, listed his cause of death as “deferred” pending an autopsy.

In a statement posted to Mr. Petty’s Facebook page on Friday, his wife, Dana, and daughter, Adria, wrote that Mr. Petty suffered from “many serious ailments including emphysema, knee problems and most significantly a fractured hip,” but that he continued to tour, worsening his conditions. “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,” the statement said.

Reports of the hip fracture emerged in October, after Petty’s death.

Late rock icon Tom Petty completed his final tour with a hairline fracture in his left hip.

The I Won’t Back Down hitmaker’s longtime manager, Tony Dimitriades, reveals he advised the singer against embarking on his massive 40th anniversary tour of North America with his band Tom Petty & The Heartbreakers until he had the injury fixed, but the star refused to listen.

“I don’t know how it happened – I don’t think he even knew when it happened,” Dimitriades tells Rolling Stone magazine, recalling Petty’s response to his word of warning as, “Why not? I’ll do it (tour) in a chair if I have to.”

He had apparently decided to retire from the road after his last tour, but wanted to finish it for his fans.

What a shame.
