Former Hollywood child star and television actor Hayden Panettiere, known for her leading roles on hit U.S. series *Heroes* and *Nashville*, died from combined drug toxicity involving fentanyl, Xanax and multiple other controlled substances, official autopsy results from the Greenville County Coroner’s Office in South Carolina have confirmed.
The coroner’s investigation has ruled the 36-year-old’s death an accidental overdose, with no physical trauma identified as a contributing factor to her passing. Panettiere was found unresponsive at a private residence in South Carolina last month, and first responders immediately deployed advanced cardiac life support protocols upon arrival, though all resuscitation attempts ultimately failed, per the coroner’s official statement.
Toxicology screens also detected two additional prescription medications in Panettiere’s system: methocarbamol, a common muscle relaxant, and quetiapine, an antipsychotic prescribed to manage a range of mood and mental health disorders. Panettiere had been open for years about her long-standing struggles with substance use disorder, and just months before her death, she released a memoir that detailed her experiences with addiction and postpartum depression at length.
According to the initial police report filed on the day of Panettiere’s death, her ex-boyfriend Brian Hickerson — who has previously publicly admitted to physically abusing Panettiere — and Hickerson’s brother Zack were present at the residence when emergency medical services arrived. Local law enforcement has been joined by agents from the U.S. Drug Enforcement Administration (DEA) in their ongoing investigation into the source of the drugs involved in Panettiere’s overdose.
Panettiere’s death has thrown a renewed spotlight on the well-documented crisis of substance abuse among former child entertainers, an issue often linked to the extreme industry pressure and early public scrutiny that young performers face throughout their careers. It also comes amid the ongoing nationwide opioid epidemic in the U.S., where illicitly manufactured fentanyl has killed more than 300,000 Americans across the last five years, according to federal public health data.
