Hayden Panettiere, the beloved actress known for her roles in “Heroes” and “Nashville”, died on August 16 at the age of 36. The Greenville County Coroner's Office confirmed her death was due to the toxic effects of fentanyl, 4-ANPP, alprazolam (Xanax), methocarbamol, and quetiapine, ruling it an accident.157

At approximately 1:51 PM, a 911 call reported a cardiac arrest at a residence in Greenville, South Carolina. First responders found Panettiere unconscious and initiated life support measures, but she was pronounced dead at 2:32 PM.

The coroner's report indicated there were no signs of trauma contributing to her death, and the Greenville Police Department stated that no foul play was suspected. An acquaintance of Panettiere placed the 911 call, and her boyfriend, Brian Hickerson, later provided authorities with a bag of her medications.4

Panettiere's representatives condemned speculation surrounding her death, emphasizing that outsiders were using the tragedy to fuel gossip. They stated, “Many people who were not close to Hayden are using her death as an opportunity to fuel gossip and speculation about a situation they knew very little about.” They urged respect for her memory and highlighted that those close to her are cooperating with the investigation to uncover the truth.

The actress began her career at age 5 and gained fame for her role in “Remember the Titans” and later in the NBC series “Heroes”. She was also a fan-favorite in the “Scream” franchise, appearing in both “Scream 4” and “Scream VI”.6
