The death of the American actress and mother of Volodymyr Klychko’s daughter, Hayden Panettiere, was ruled an accident caused by the toxic effects of multiple illicit and prescription drugs. NBC News reports this, citing the Greenville County Coroner’s Office report in South Carolina.
The cause of death for the 36-year-old star was the toxic effects of fentanyl, 4-ANPP, alprazolam, methocarbamol, and quetiapine. No signs of trauma that could have caused death were found. The manner of death was determined to be accidental.
In the weeks before her death, the actress was in a rehabilitation center. In the Airbnb apartment where she was staying, investigators found blue pills that tested positive for fentanyl, as well as a white powdery substance in a sunglasses case. Panettiere’s father said she had planned to spend her birthday in Greenville and then travel to Ukraine to visit her daughter.
At the initial stage of the investigation, police did not find signs of a violent death. The investigation is ongoing, and Panettiere’s death is also being examined by the U.S. Drug Enforcement Administration (DEA).
Panettiere died on 16 August, a few days before her 37-birthday. She was found unresponsive in a residential complex in South Carolina. When emergency responders arrived, her boyfriend Brian Hickerson and his brother Zach were with her.
Panettiere became known as a child actor, and her breakthrough role was Claire Bennet on the series Heroes. She later starred as one of the leads on the series Nashville and was twice nominated for a Golden Globe. Panettiere is also known for roles in the films Remember the Titans, Raising Helen, Ice Princess, and Scream 4.
The actress spoke openly about addiction and postpartum depression. In May 2026 she published her memoir, This Is Me: Redemption, in which she described, among other things, her struggle with addiction and the difficult period after the birth of her daughter with Ukrainian boxer Volodymyr Klychko in 2014. In 2018 Panettiere transferred custody of their daughter to Klychko.
