Hayden Panettiere’s Cause of Death Confirmed as Fentanyl Overdose, Autopsy Shows

The Greenville County Coroner’s Office confirmed that actress Hayden Panettiere died from the toxic effects of fentanyl, Xanax, methocarbamol, and quetiapine, according to an autopsy completed after the 36-year-old was found unresponsive at a South Carolina residence in August, BBC reports. The coroner ruled her death an accident with no signs of trauma contributing to her passing.

Autopsy Details and Drug Findings

The autopsy revealed Panettiere had multiple substances in her system, including fentanyl—a synthetic opioid linked to hundreds of thousands of overdose deaths in the U.S. over the past five years—and alprazolam (Xanax). Additional drugs included methocarbamol, a muscle relaxant, and quetiapine, an antipsychotic medication. Emergency responders attempted advanced cardiac life support but could not revive her, NBC News notes.

History of Substance Abuse and Personal Struggles

Panettiere, known for her roles in “Heroes” and “Nashville,” had openly discussed her battles with substance abuse and postpartum depression. In her memoir, “This Is Me: A Reckoning,” she detailed being introduced to drugs at 16 during a red carpet event, where a team member gave her a “happy pill.” She later described how drugs and alcohol became “something I almost couldn’t live without,” BBC reports.

Her brother, Jansen, died at 28 from a heart condition, and Panettiere revealed he struggled with heroin and cocaine use before his death. She also wrote about having a daughter with Wladimir Klitschko in 2014 and the challenges of motherhood, which she said led to heavy drinking and eventual rehab, NBC News states.

Investigation and Legal Context

Her on-again, off-again boyfriend, Brian Hickerson, was present when she collapsed. A police report noted he showed authorities a “bag of medication” he claimed she was taking. Hickerson, who pleaded no contest to a charge of injuring a spouse or girlfriend in 2019, was part of an ongoing DEA investigation into her death, NBC News reports. His attorney stated there was no foul play, but the case remains under review.
