Hayden Panettiere, the American actress known for her roles in the television series "Heroes" and "Nashville," died at the age of 36 in Greenville, South Carolina. Authorities confirmed that she was found unresponsive at an apartment west of downtown Greenville on Sunday afternoon, where emergency responders attempted advanced cardiac life support measures but pronounced her dead at 2:32 p.m. Local police indicated that preliminary investigations revealed no signs of foul play or trauma, and the cause and manner of death remain pending further examination.

An acquaintance reportedly called 911 shortly before the discovery, and reports suggest that a nasal spray used to reverse opioid overdoses, Narcan, was found at the scene. Some sources noted the residence belonged to Brian Hickerson, a former boyfriend who was convicted in 2021 on felony charges related to injuring Panettiere during their relationship.

Panettiere’s career in the entertainment industry began in early childhood with commercials and soap operas. She gained widespread recognition as Claire Bennet, the supernaturally gifted cheerleader on the NBC series "Heroes" (2006-2010). Later, she portrayed Juliette Barnes, a troubled country music star on the ABC drama "Nashville," for which she received two Golden Globe nominations. Panettiere also appeared as Kirby Reed in the "Scream" film franchise, reprising the role most recently in "Scream VI" (2023).

Throughout her life, Panettiere was open about her challenges with mental health and substance abuse. She disclosed struggles with body dysmorphia beginning in her teenage years and battled postpartum depression following the birth of her daughter Kaya in 2014 with Ukrainian boxer Wladimir Klitschko. According to Panettiere, her experiences influenced her character’s storylines on "Nashville," which included themes of addiction and postpartum depression. She briefly left the series in 2015 to seek treatment.

Panettiere’s family described her as a bright presence who brought joy to those around her and to audiences worldwide. Her father, Skip Panettiere, called her an “incredible light and a force of nature.” Tributes from colleagues in Hollywood highlighted her talent and impact, with remarks emphasizing her professionalism and vivacity.

Her personal life included a lengthy custody arrangement concerning her daughter, who now lives in Europe under Klitschko’s care. Panettiere also endured family hardships, including the death of her younger brother Jansen Rane Panettiere in 2023, who had a history of substance abuse.

Born on August 21, 1989, and raised in Palisades, New York, Panettiere spent nearly her entire life in the public eye. In her memoir, published earlier this year, she reflected on the pressures of fame, the complexities of family dynamics, and the ongoing process of personal growth. Despite her struggles, she expressed optimism and a determination not to be defined by adversity.

The investigation into her death is ongoing as officials await the final autopsy results.
