An autopsy found no signs of trauma that contributed to her death.

Panettiere’s father, Skip Panettiere, confirmed her death. “It is with profound sadness that we share the tragic passing of our beloved Hayden,” he said in a statement, according to The Hollywood Reporter.

“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.”

Panettiere spoke openly about mental health, substance use

Panettiere had been open about her experiences with mental health and substance use in the years before her death.

In her memoir, “This Is Me: A Reckoning,” published in May, she wrote about her experiences with postpartum depression, addiction, and recovery, among other deeply personal aspects of her life.

While promoting the book in an interview on the “Jay Shetty Podcast”, Panettiere discussed experiencing anxiety and panic attacks after the birth of her daughter and while filming “Nashville.”

She also described turning to alcohol during that period. She later gave up custody of her child.

“I was miserable. I was in tears all the time. Even though the alcohol helped my nervous system calm down, it is a depressant, so over time it made things worse, not better,” she told Shetty.
