Hayden Panettiere’s Cause of Death Revealed

“However, resuscitation efforts were unsuccessful,” the coroner’s office said in their press release, noting that Panettiere pronounced dead at the scene around 2:32 p.m. “At autopsy, no signs of trauma were discovered that would have contributed to the death.”

Panettiere’s dad Alan “Skip” Panettiere confirmed her passing on Aug. 16, telling People in a statement, “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.”

The Bring It On: All or Nothing alum’s death came three years after her family weathered another tragedy in the death of her 28-year-old brother Jansen Panettiere, who she said experimented with drugs before he passed away from heart complications.

“You’re just riddled with guilt that you didn’t do your job, and especially what took him was something that I, of all people, should have understood,” she told E! News in May 2023. “I miss him all the time.”

However, Panettiere noted at the time that she tried “not to get too wrapped up” in her grief.
