New details surrounding the death of Hayden Panettiere are emerging as authorities continue to investigate what caused the actress’ death at 36.

Panettiere’s representative confirmed her death to USA TODAY on Sunday, Aug. 16.

“It is with profound sadness that we share the tragic passing of our beloved Hayden,” her father, Skip Panettiere said in a statement her rep shared. “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.”
