An autopsy on actress Hayden Panettiere revealed no signs of trauma that would have contributed to her death at 36, but the Greenville County Coroner's Office says the cause and manner of death remain pending as investigators continue additional studies.
Panettiere was found unresponsive inside a South Carolina Airbnb on August 16, 2026, where she had been temporarily staying. The Greenville County Coroner's Office said a 911 call came in at approximately 1:51 p.m. reporting a cardiac arrest. First responders and Emergency Medical Services arrived and found a woman in cardiac arrest. EMS crews began advanced life-saving measures, but those efforts failed. Page Six reported that Panettiere was pronounced dead at 2:32 p.m.
The coroner's office identified the decedent as Hayden Lesley Panettiere, 36, of California. In a written statement, the office confirmed that an autopsy had been completed and that "no signs of trauma were discovered that would have contributed to the death." But investigators stopped short of naming a cause. The case, the coroner said, "remains active and ongoing."
That gap, between a completed autopsy and an undetermined cause of death, leaves the public with more questions than answers. The coroner noted that additional studies will be completed, a reference that typically points to toxicology testing, which can take weeks or longer to finalize.
While the coroner's office has not confirmed a cause, 911 dispatch audio obtained from the scene referenced an apparent "overdose" during the emergency response. The coroner's formal statement made no mention of that characterization, and authorities have not confirmed or denied it.
Just The News reported that Panettiere was found unresponsive at the Judson Mill Lofts in Greenville, South Carolina, and that a preliminary investigation found no signs of foul play or suspicious circumstances. That finding aligns with the coroner's autopsy results showing no trauma.
Panettiere had flown from Los Angeles to South Carolina on Saturday, the day before the 911 call, with Brian Hickerson, her on-again, off-again boyfriend. Hickerson is originally from South Carolina. It remains unclear whether he placed the 911 call.
Hickerson's presence at the scene adds a layer of unease to an already painful story. He was first linked to Panettiere in 2018. By 2021, he had pleaded no contest to two felony counts of injuring a spouse or girlfriend. A court sentenced him to 45 days in county jail, four years of probation, and 52 domestic violence classes. He also received a five-year restraining order requiring him to stay away from Panettiere.
Whether that restraining order was still in effect at the time of the South Carolina trip is not addressed in any official statement released so far. The coroner's finding of no trauma may ease one set of concerns, but the broader circumstances remain under active investigation.
Panettiere's father, Skip Panettiere, confirmed her death in a statement to Page Six on Sunday.
"It is with profound sadness that we share the tragic passing of our beloved Hayden. She was an incredible light and a force of nature who brought immeasurable love and joy to all who knew her, and to the millions who watched her onscreen. We ask for privacy as our family takes time to process this unimaginable loss."
Panettiere was a child actress who grew into one of television's most recognizable faces. She starred in NBC's "Heroes," ABC's "Nashville," and appeared in "Scream 4." Earlier this year, she published a memoir titled "This Is Me: A Reckoning," which detailed her struggles with addiction, postpartum depression, and the personal cost of growing up in the entertainment industry.
In a 2022 interview with People, Panettiere described how substance abuse entered her life when she was still a teenager. She said she was offered pills before red carpet appearances when she was just 15 years old.
"They were to make me peppy during interviews. I had no idea that this was not an appropriate thing, or what door that would open for me when it came to my addiction."
In a separate 2023 interview with Women's Health, AP News reported that Panettiere said, "I was the one who put myself in the first treatment center. I was drowning." She had spoken publicly about opioid and alcohol addiction that followed years of untreated postpartum depression after the birth of her daughter, Kaya, now 11.
Kaya lives in Ukraine with her father, former boxing champion Wladimir Klitschko, Panettiere's ex-fiancé. Panettiere's memoir detailed the custody decision and the depression that surrounded it, a chapter of her life she described with unflinching honesty.
The family had already endured devastating loss. Panettiere's younger brother, Jansen, died in February 2023 at age 28 from an undiagnosed heart condition. Musician Clayton Johnson, a friend of Panettiere's, posted an Instagram tribute after her death that referenced Jansen. Fox News reported that Johnson shared a video of himself and Panettiere singing together and revealed the last text she ever sent him: a sincere wish for world peace.
"It's been a couple of weeks since our last phone call, but the last thing you ever texted me was, Honestly, people think it's a joke to ask for world peace, but that would be me. That was you in a nutshell."
The Washington Examiner reported that preliminary investigation showed no signs of foul play or suspicious circumstances. That tracks with the coroner's autopsy finding of no trauma. But "no foul play" is not the same as a confirmed cause of death, and investigators have made clear they are not finished.
The pending toxicology results will likely determine whether substance abuse played a role. Given Panettiere's own public disclosures about addiction, and the dispatch audio's reference to a suspected overdose, those results carry significant weight.
Breitbart noted that Panettiere's representative announced her passing on Sunday, and that her memoir, published just months before her death, had laid out in detail the personal battles she had fought for most of her adult life.
Panettiere had been open about those battles in a way that few public figures manage. Her memoir laid bare a lifetime of addiction and abuse, from pills handed to a teenager before press events, to opioid dependency, to the anguish of giving up custody of her daughter. She did not hide from any of it.
The Substance Abuse and Mental Health Services Administration (SAMHSA) operates a National Helpline at 1-800-662-HELP (4357) for individuals and families facing substance use disorders. The National Domestic Violence Hotline can be reached at 1-800-799-SAFE (7233).
Hollywood handed Hayden Panettiere pills at 15 and called it preparation. She spent two decades paying the price. The least the system owes her now is a straight answer about how she died.
