The Greenville County Coroner's Office in South Carolina has officially determined the cause and manner of death for actress Hayden Panettiere following her passing on August 16. Medical examiners confirmed that the 36-year-old performer died from the combined toxic effects of fentanyl alongside several other substances, including 4-ANPP, alprazolam, methocarbamol, and quetiapine.
