Quick Summary

Actress Hayden Panettiere, known for her roles in “Heroes” and “Nashville,” died Sunday after being found in cardiac arrest at a residence in Greenville, South Carolina. Emergency personnel responded to a 911 call reporting a cardiac arrest Sunday afternoon and found the 36-year-old actress unresponsive inside a home where she had been temporarily staying. An autopsy was completed Monday, and the coroner’s office said no signs of trauma were discovered that would have contributed to her death, though an official cause has not yet been released.

What Happened

Police and EMS personnel responded to Judson Mill Lofts, an apartment complex at 701 Easley Bridge Road in Greenville, following a report of an unresponsive female around 1:51 p.m. Sunday. Responders administered medical assistance and initiated advanced cardiac life support measures, but resuscitation efforts were unsuccessful, and Panettiere was pronounced dead at 2:32 p.m.

Greenville police said their preliminary investigation had not indicated any signs of foul play or suspicious circumstances. The reason for Panettiere’s presence in Greenville remains unclear, though her “Nashville” co-star Charles Esten had performed a concert at The Foundry, a venue sharing the same address as the apartment complex, two days earlier on Friday. Police have not confirmed any connection between the concert and her presence in town.

Panettiere’s father confirmed her death in a public statement, writing that it was with profound sadness that the family shared her tragic passing, and describing her as an incredible light and force of nature who brought immeasurable love and joy to everyone who knew her, as well as to the millions who watched her on screen. She would have turned 37 on August 21.

Hayden Panettiere

Background

Panettiere rose to fame in the early 2000s, becoming widely known for playing cheerleader Claire Bennet on the NBC series “Heroes” and later for portraying a rising country music star on the drama “Nashville.” She stepped back from the public spotlight at points in her career as she dealt with challenges related to addiction and mental health.

In recent years, Panettiere had been increasingly open about those struggles. She released a memoir titled “This Is Me: A Reckoning,” in which she wrote about her childhood fame, motherhood, mental health, and the loss of her younger brother, actor Jansen Panettiere, who died in 2023 at age 28 from cardiomegaly, an enlarged heart, along with aortic valve complications. She later spoke publicly about how deeply her brother’s death affected her both mentally and physically.

Panettiere shares a daughter, Kaya, with former fiancĂ© Wladimir Klitschko, the Ukrainian heavyweight boxing champion. Panettiere gave up custody of Kaya to Klitschko, a decision she said she made because she believed it would be better for their daughter. She had also publicly supported Ukraine following Russia’s 2022 invasion, launching a relief fund that year to raise money for medical supplies and protective gear, saying at the time that she could not continue to sit on the sidelines while people she knew in the country suffered.

Her career had recently experienced a resurgence, with roles in the 2024 film “Amber Alert” and the 2026 film “Sleepwalker.” That renewed momentum made news of her death especially shocking to those who knew her, with friends and former co-stars writing publicly that everything had seemed to be turning around for her.

Why It Matters

Panettiere’s death adds to a difficult recent chapter for a family that lost her younger brother just three years earlier under separate medical circumstances. Her openness in recent years about her struggles with addiction, agoraphobia, and grief had positioned her as a relatively candid public voice on mental health topics within Hollywood, making her sudden death resonate widely among fans and colleagues who had followed her recovery journey through her memoir and public interviews.

The absence of a confirmed cause of death, despite the completed autopsy showing no signs of trauma, leaves open questions that investigators are continuing to examine. Toxicology results, which typically take additional time to process, may play a role in eventually determining the full circumstances of her death.
