One of Tom Petty’s daughters is speaking out about her father’s death after his autopsy report revealed that the rocker died of an accidental prescription drug overdose.

"My dad in the past openly overcame a crippling drug problem with no shame," Petty’s daughter AnnaKim Petty shared on her Instagram page. "His recent death is tragic, yet he died from doing what he loved and what will continue to keep his spirit alive: touring with a broken hip because he would have it no other way.”

On Friday, Jan. 19, Petty’s family shared the news of the musician’s cause of death with fans on the official Tom Petty and the Heartbreakers Facebook page.

In the lengthy message, the post read, “Our family sat together this morning with the Medical Examiner – Coroner’s office and we were informed of their final analysis that Tom Petty passed away due to an accidental drug overdose as a result of taking a variety of medications.”

After the report of Petty’s cause of death was made public, speculation about the singer’s drug addiction arose. In the past, Petty had been open about his struggles with heroin, but it is unclear whether or not the 66-year-old had relapsed. But AnnaKim ignored the rumors and theories in her heartfelt post to her late father.

The family also explained that Petty suffered a painful fractured hip before he died.

“Unfortunately Tom’s body suffered from many serious ailments including emphysema, knee problems and most significantly a fractured hip,” the family said on Facebook. “Despite this painful injury he insisted on keeping his commitment to his fans and he toured for 53 dates with a fractured hip and, as he did, it worsened to a more serious injury.”

AnnaKim also thanked fans for giving the family space during their difficult time.

"He loved performing," she said. "There are no hypothetical questions — I love my dad and feel he is an immortal badass. The amount of pain his hip caused was beyond a normal surgery. He is at peace, out of pain. I thank you for respecting my family's privacy and inviting love during this shocking new chapter.”
