Toxicology Findings and Official Cause of Death

According to official findings from the Greenville County Coroner’s Office, the actress succumbed to the toxic effects of multiple substances. Her toxicology report confirmed the presence of fentanyl, 4-ANPP, alprazolam, methocarbamol, and quetiapine.

First responders were originally dispatched following an urgent afternoon 911 call reporting a woman experiencing cardiac arrest.

Despite immediate life-saving interventions, medical personnel pronounced Panettiere dead at the scene at 2:32 p.m.
