"I had no idea that this was not an appropriate thing, or what door that would open for me when it came to my addiction," said Panettiere in an interview.

Hayden Panettiere

Actress Hayden Panettiere, known for her roles in Heroes and Nashville, died at age 36 after authorities found her unresponsive at a Greenville County, South Carolina, residence about a month ago.


The coroner’s office completed an autopsy that identified fentanyl and Xanax among the toxic substances in her system, along with methocarbamol (a muscle relaxant) and quetiapine (an antipsychotic). No signs of external trauma were detected, and the coroner described the death as accidental.


Panettiere had spoken openly about her ongoing struggles with addiction and postpartum depression, publishing a memoir earlier this year that detailed her personal battles.


Emergency responders initiated advanced life‑support measures but could not revive her. The U.S. Drug Enforcement Administration is cooperating with local officials to investigate the case.


At the time of her death, her former partner Brian Hickerson and his brother Zack were present in the home according to police reports.
