Toxicology Findings and What Officials Uncovered at the Scene

First responders discovered Hayden Panettiere unresponsive on a sofa bed at an Airbnb in Greenville, South Carolina, on August 16. Despite life-saving efforts by emergency personnel, she was pronounced dead at the scene at 2:32 p.m.

The Greenville County Coroner’s Office determined that Panettiere died from the lethal combination of multiple substances. Her toxicology panel revealed toxic levels of five distinct compounds:

• Fentanyl: A potent synthetic opioid.
• 4-ANPP: A direct precursor and metabolite related to fentanyl.
• Alprazolam: A prescription benzodiazepine commonly used to treat anxiety.
• Methocarbamol: A prescription muscle relaxant.
• Quetiapine: A prescription antipsychotic medication.

An official autopsy confirmed there were no physical signs of trauma or external injuries that contributed to her passing. However, investigators located suspected narcotics, prescription pill bottles, and drug paraphernalia inside the rental unit.

The Critical 911 Call and On-Scene Revival Efforts

Panettiere was staying at the South Carolina residence alongside her on-again, off-again boyfriend, Brian Hickerson, and his brother, Zach Hickerson. It was Zach who initially discovered the actress unresponsive while Brian remained asleep in an adjacent room.

According to the official coroner’s documentation, rapid emergency actions were taken before first responders arrived at the residence:

1. Emergency Intervention: One of the brothers administered two separate doses of Narcan, a nasal spray engineered to block and reverse opioid toxicity.
2. Dispatch Contact: The brothers dialed 911 immediately after noticing she remained unresponsive.
3. Physical Resuscitation: Bystander CPR was performed continuously until paramedics arrived on site.
4. Paramedic Care: Emergency medical teams conducted advanced resuscitation protocols before officially pronouncing her death.

Behind the Scenes: Panettiere’s Recent Struggles and Treatment

Panettiere’s father, Skip Panettiere, shared critical context with investigators regarding his daughter’s ongoing health battles. He confirmed she had experienced a prior overdose and entered a residential rehabilitation program in Malibu, California, for two to three weeks.

She had completed that treatment program just weeks prior to her passing in South Carolina. Her father noted that while her struggles with chemical dependency began in her early twenties, her challenges grew significantly heavier following severe postpartum depression after giving birth to her daughter, Kaya.

The actress candidly detailed these intensely personal battles in her published memoir, “This Is Me: A Reckoning,” which was released in May. The book documented her experiences navigating postpartum depression, substance abuse, and turbulent relationship dynamics.

Her relationship with Brian Hickerson began in 2018 following her separation from former world heavyweight boxing champion Wladimir Klitschko. Hickerson’s past interactions with law enforcement involved multiple domestic abuse arrests, culminating in a 2021 no-contest plea to two felony counts of injuring a spouse or cohabitant, which resulted in 45 days in jail and four years of probation.
