Hayden Panettiere’s Death: Everything We Know About Her Final Hours

Hayden Panettiere‘s loved ones and peers are looking for answers.

The actress died in Greenville, South Carolina, on Aug. 16, with the city’s coroner noting in his report that emergency medical services were unable to resuscitate her after finding her in cardiac arrest. And though audio from the 911 dispatch call obtained by multiple outlets features responders discussing an apparent overdose, the official cause and manner of death have yet to be released pending further investigation.

After Panettiere’s sudden passing, tributes poured in from several of her former costars, including Connie Britton from Nashville, James Kyson from Heroes, Solange from Bring It On: All or Nothing and Kim Cattrall from Ice Princess.

Meanwhile, those who worked alongside her more recently, like Justin Chatwin from her final film Sleepwalker, provided insight into how she was doing in the run-up to her death.

“I could tell she was struggling, and I was like, ‘I don’t think it’s this movie,'” he told People of their time on set in 2025 in an interview Aug. 17. “There’s a handful of women that I’ve worked with that I really liked, and I really loved working with her, but I also know that she was really lonely.”
