American actress Hayden Panettiere died at age 36 after being found unresponsive on August 16 in a Greenville, South Carolina apartment. Emergency responders performed resuscitation efforts, but she was pronounced dead at the scene. Authorities and the U.S. Drug Enforcement Administration are currently investigating the circumstances surrounding the death.
The sudden death of American actress Hayden Panettiere has drawn federal law enforcement involvement as authorities examine the medications present at the scene according to reporting from local coverage. Best known for her roles in the television series Heroes and Nashville, the 36-year-old actress was discovered in her apartment in Greenville, South Carolina.
Earlier, in May 2026, she released a memoir titled This Is Me: A Reckoning, in which she wrote candidly about her multi-year struggle with alcohol and opioid addiction, postpartum depression, and complex personal relationships.
Inside the Greenville Apartment Discoveries
The sequence of events leading to the emergency response began in the early afternoon. Zack Hickerson, the brother of Panettiere’s boyfriend Brian Hickerson, found the actress unresponsive in an armchair in the living room at approximately 13:30. At that moment, Brian Hickerson was asleep in an adjacent room. Unable to wake her, the brothers immediately dialed 911. They informed the dispatcher that they could not bring Hayden to her senses, while words about an “overdose” and “cardiac arrest” were heard during the same conversation.
Emergency dispatchers received calls indicating a possible drug overdose and cardiac arrest. Medical personnel arrived quickly and performed resuscitation efforts for nearly an hour, trying to save the actress. Panettiere was officially recognized as dead in the presence of the brothers. According to a police officer present at the scene, Zack looked very emotional and agitated while efforts were made to save Hayden, whereas Brian was calm and only began to worry when medics declared the actress dead.
Medication Recovery and Federal Involvement
Following the emergency response, law enforcement examined the contents of the residence. Brian Hickerson showed police a bag containing medications that the actress had been taking at the time of her death. While the formal police report obtained by media outlets redacted the specific list of pharmaceuticals, American media reports indicate the bag contained nine different substances. Authorities also recovered Narcan, a medication used for emergency response in opioid overdoses. The U.S. Drug Enforcement Administration (DEA) has joined the ongoing investigation into Panettiere’s death.
Investigators emphasize that an official determination of the cause of death remains premature. An initial autopsy revealed no signs of injuries, and the final cause and circumstances of death remain unestablished as investigators await additional studies, including toxicology. Law enforcement has found no signs of foul play so far. In response to numerous media inquiries, the Hickerson brothers have not responded since then.
Subsequent Police Visits to the Residence
Days after the incident, law enforcement returned to the property where the Hickerson brothers reside. According to People, police officers visited the home on August 19 following a request regarding a social welfare check on the house where the Hickerson brothers live. Police arrived at the house at approximately 8:20 in the morning, knocked on the door, waited a few minutes, but no one opened the door. Authorities stressed that this call was not related to the investigation into Hayden Panettiere’s death.
Panettiere is survived by her 11-year-old daughter, Kaya, from her former fiancé, Ukrainian boxer Wladimir Klitschko. As toxicologists continue their laboratory work, the article notes that Hayden’s mother also strangely spoke out about her sudden death.
