Hayden Panettiere was found unresponsive Sunday afternoon in Greenville, South Carolina, and died after emergency crews tried to revive her, leaving serious questions about what happened in her final hours. Dispatch audio from the emergency response referenced an overdose, but authorities have not confirmed that drugs caused the 36-year-old actress’s death.
According to PEOPLE, Greenville police and emergency medical personnel responded to a residence at about 1:50 p.m. on August 16 after receiving a report of an unresponsive woman. An acquaintance placed the 911 call. Emergency responders attempted lifesaving measures before Panettiere was pronounced dead. Dispatch audio captured officials discussing both an “overdose” and “cardiac arrest” during the emergency response.
That reference has placed a possible overdose at the center of early questions surrounding Panettiere’s death reports, but it is not an official cause of death. The preliminary investigation showed no signs of foul play or suspicious circumstances. The Greenville County Coroner’s Office is handling the death investigation and will determine the cause following an autopsy. The Associated Press also reported that Panettiere was pronounced dead after lifesaving efforts failed.
The uncertainty surrounding her death carries added weight because Panettiere spent years speaking candidly about addiction, depression, and the difficult work of getting sober. Those struggles are part of her history.
Panettiere first publicly detailed the depth of her addiction in a 2022 interview with PEOPLE. She said she had struggled with alcohol and opioids while her career continued to grow and recalled being given what she called “happy pills” by someone on her team when she was 15. She said her substance use later became increasingly difficult to control away from work. Looking back on that period, she described herself as being in a “cycle of self-destruction.”
Her mental health became even more complicated after the December 2014 birth of her daughter, Kaya, whom she shared with former fiancé Wladimir Klitschko. Panettiere repeatedly spoke about experiencing severe postpartum depression. During a Good Morning America interview, she explained that she struggled to separate what was happening with her drinking from what was happening emotionally.
“I just knew I was deeply depressed,” she said.
In a detailed Women’s Health interview in 2023, Panettiere said her drinking had begun escalating years earlier as she used alcohol to cope with stress. After giving birth, she described experiencing extreme hopelessness while her drinking intensified. She also said opioids entered the picture after an old neck injury caused significant pain and her tolerance increased quickly. Panettiere entered a treatment center during the production of “Nashville” in 2015, telling the magazine, “I was drowning.” She later returned to treatment and participated in therapy and a 12-step recovery program.
By 2024, Panettiere was publicly talking about recovery with far more optimism. In another PEOPLE interview, she told people struggling with addiction that “Recovery is real. It can happen.” She also stressed that remembering her history with addiction remained important to staying sober rather than pretending that chapter of her life had disappeared.
Her progress was tested by another devastating loss. Panettiere’s younger brother, Jansen, died unexpectedly from a heart condition in February 2023 at age 28. In a September 2024 interview with PEOPLE, she said his death left her feeling as though she had lost half her soul. She also said grief contributed to the return of agoraphobia and damaged her confidence, even as she worked to regain stability and continue moving forward.
Panettiere revisited the darkest years of her addiction just months before her death in her memoir, “This Is Me: A Reckoning,” released in May 2026. She wrote about alcohol becoming a way to temporarily escape anxiety, depression, relationship trauma, and separation from her daughter. She also revealed that after developing jaundice, a doctor warned her that continued drinking could leave her “dead within five years.” Panettiere wrote that treatment eventually brought back feelings of calm and joy that addiction had stripped away.
Those words are especially painful in the wake of Panettiere’s death, but they still cannot be treated as evidence of how she died. What is known is that her history with addiction and depression gives important context to a life she chose to discuss with openness.
