New emergency dispatch audio has uncovered urgent details from the final moments of actress Hayden Panettiere’s life, describing responders encountering both cardiac arrest and a suspected overdose during the critical response to her unresponsive condition.

Panettiere, 36, was discovered unresponsive at approximately 1:51 p.m. Sunday afternoon in her apartment at the Judson Mill Lofts in Greenville, South Carolina. Emergency personnel administered advanced cardiac life support, including chest compressions, but she was pronounced dead at the scene at 2:32 p.m.

The dispatch recording includes distinct references to “cardiac arrest” and a suspected overdose—language that emerged prior to any autopsy results or toxicology reports from authorities. Police confirmed no signs of foul play or suspicious circumstances in their preliminary investigation, while the Greenville County Coroner’s Office stated an autopsy was underway to determine her official cause of death.

Panettiere’s father, Skip Panettiere, issued a family statement remembering his daughter as “an extraordinary light” who brought joy to countless individuals and millions through her work. The actress, known for roles in Heroes, Nashville, and the Scream franchise, had spoken publicly about alcoholism, postpartum depression, and her journey through treatment following the sudden death of her younger brother, actor Jansen Panettiere, in 2023.

The dispatch audio provides a timeline of the emergency response without confirming medical conclusions. Cardiac arrest describes heart cessation but does not identify its root cause, while the overdose reference reflects initial field observations—not final toxicology or coroner findings. Authorities emphasize that the official cause of death remains pending after the autopsy.

Panettiere, who would have turned 37 on Friday, is survived by her daughter, Kaya. Her representative confirmed police were called shortly before 2 p.m. after an acquaintance found her unresponsive, and lifesaving measures were immediately initiated.
