### Official coroner's report

The statement from the Greenville County Coroner's Office explicitly states: "The cause of death is determined to be the toxic effect of fentanyl, 4-ANPP, alprazolam, metocarbamol, and quetiapine. The death is ruled an accident." The initial publicly released report did not disclose the exact concentrations of the substances found in the body, leaving some details open to possible further clarification by investigative and medical authorities.

### Substances found in the actress's body

Among the identified compounds were fentanyl, a potent synthetic opioid, as well as 4-ANPP, a chemical byproduct associated with the manufacture of fentanyl. In addition, the body was found to contain alprazolam (known by the brand name Xanax, used for anxiety and panic disorders), metocarbamol — a muscle relaxant prescribed for muscle spasms — and quetiapine — an antipsychotic medication used to treat a range of mental disorders. It was the combined toxic effect of this combination, according to the coroner, that led to the fatal outcome.

### Circumstances of death

Hayden Panettiere died on August 16, 2026, in Greenville, where she was temporarily staying at the time. A call to emergency services came in at approximately 13:51 due to cardiac arrest.
