Hayden Panettiere cause of death ruled accidental drug toxicity

Hayden Panettiere died from the combined toxic effects of fentanyl, 4-ANPP, Alprazolam, Methocarbamol and Quetiapine.

The Greenville County Coroner's Office confirmed the cause to Variety, and ruled the manner of death an accident. Cause refers to the physical agents involved. Manner is the separate classification used to record how the death occurred.

Two of the substances named in the ruling will be familiar to many readers under other descriptions. Alprazolam is more widely recognised under the brand name Xanax. 4-ANPP is a chemical intermediate used to illegally manufacture fentanyl. The coroner listed Methocarbamol and Quetiapine alongside those substances without additional description in the material reported.

Panettiere died on 16 August in Greenville, South Carolina. She was 36, and had been temporarily staying at the residence where she was found. The confirmation was published on 22 September.

It closes more than a month of uncertainty in the official record. As of 16 September, the coroner had said the cause and manner remained pending further investigation and toxicology results, despite national reports circulating at the time, according to Upper Michigan's Source. Toxicology testing, the laboratory analysis of blood and tissue samples, often takes several weeks to complete.

The account of the final day centres on an emergency call in the early afternoon. A 911 call reporting a cardiac arrest, a report that someone had collapsed and was unresponsive, was received at approximately 1:51 p.m. The caller was described as an acquaintance of Panettiere.

First responders found her unconscious inside the residence. Crews began life-support measures at the scene, the emergency efforts used to maintain breathing and circulation. She was pronounced dead at 2:32 p.m., a little over 40 minutes after the call came in.

The Greenville Police Department told Variety that no foul play was suspected. That assessment means investigators did not see evidence of another person causing harm. The coroner's statement also said there were no signs of trauma, meaning physical injury, that contributed to her death.
