Hayden Panettiere, the actress best known for playing cheerleader-turned-hero Claire Bennet on NBC’s Heroes and country star Juliette Barnes on Nashville, has died. She was 36. Panettiere was found unresponsive and in cardiac arrest at a residence in Greenville, South Carolina, on Sunday, August 16, 2026; resuscitation efforts were unsuccessful, and she was pronounced deceased that afternoon. Her representative confirmed her death to ABC News. In the weeks since, the Greenville County Coroner’s Office has ruled her death accidental, attributing it to the toxic effects of fentanyl combined with several other substances — a finding federal investigators are still examining as part of a broader inquiry into how she obtained the drugs involved.
