Hayden Panettiere, 36, died from an accidental drug overdose, the Greenville County Coroner’s Office confirmed Tuesday. The actress was found unresponsive in cardiac arrest at a Greenville, South Carolina, apartment on August 16, where first responders attempted resuscitation but were unsuccessful.
The coroner’s office ruled her death accidental, attributing it to the toxic effects of fentanyl, 4-ANPP, alprazolam, methocarbamol, and quetiapine. No signs of trauma were reported. Emergency responders arrived at the scene at 1:51 PM after a 911 call reported a cardiac arrest at 701 Easley Bridge Road. Panettiere was pronounced dead at 2:32 PM.
Federal agents from the DEA, alongside local authorities in South Carolina and Los Angeles, are investigating the origin of the medications found at the scene. Their inquiry remains ongoing.
Key Details from the Coroner’s Report
The autopsy findings, released Tuesday, listed the specific substances detected in Panettiere’s system. Fentanyl, a synthetic opioid, was among the drugs identified, along with 4-ANPP (a fentanyl metabolite), alprazolam (a benzodiazepine), methocarbamol (a muscle relaxant), and quetiapine (an antipsychotic). The coroner’s office did not specify quantities or ratios of these substances.
Timeline of Events
- August 16, 1:51 PM: 911 call received reporting a cardiac arrest at the Greenville apartment.
- 1:51 PM – 2:32 PM: First responders and EMS arrived, initiated advanced cardiac life support, and attempted resuscitation.
- 2:32 PM: Panettiere pronounced dead at the scene.

Investigation and Ongoing Actions
Local and federal authorities are tracing the source of the medications found at the scene. The DEA’s involvement indicates a potential focus on the supply chain of controlled substances, though no further details have been disclosed. The investigation remains active, with no arrests or additional charges announced.
Panettiere was staying temporarily in the apartment where she was found. Her on-again, off-again boyfriend, Brian Hickerson, and his brother were present at the time of her death. According to reports, Hickerson provided a bag of medications to first responders, claiming they were consumed by Panettiere. The 911 audio recordings referenced in coverage suggest an initial suspicion of overdose, though official confirmation came only after the autopsy results.
Background on the Substances Involved
- Fentanyl: A potent synthetic opioid, often linked to overdose deaths due to its strength and prevalence in illicit drug markets.
- 4-ANPP: A metabolite of fentanyl, used as a marker in toxicology to confirm fentanyl exposure.
- Alprazolam: A benzodiazepine commonly prescribed for anxiety but also misused recreationally.
- Methocarbamol: A muscle relaxant, less commonly associated with overdose risks but present in the toxicology report.
- Quetiapine: An antipsychotic medication, typically prescribed for conditions like schizophrenia or bipolar disorder.
