Police Conclude Investigation Into Hayden Panettiere’s Death
The Greenville Police Department in South Carolina has officially closed its investigation into the sudden passing of actress Hayden Panettiere. Law enforcement authorities confirmed on October 28 that, following extensive reviews and medical determinations, her tragic passing has been ruled entirely accidental.
“Based on the Medical Examiner’s determination and the findings of the investigation, Hayden Panettiere’s death has been ruled accidental,” Greenville PD said in a statement shared with Deadline. The department succinctly finalized its proceedings by stating: “The Greenville Police Department has concluded its investigation.”
Emergency Response and Cause of Death Findings
Hayden Panettiere passed away on August 16 in South Carolina at the age of 36. According to official police incident reports, ‘officers responded to a report of an unresponsive female’ at approximately 1:50 on August 16, discovering the mother-of-one deceased upon arrival. At the time of her passing, Panettiere’s on-and-off partner Brian Hickerson, 37, and his brother Zach Hickerson, 38, were present at the scene.
The definitive ruling arrives weeks after the Greenville County Coroner’s Office released its findings regarding the chemical analysis. Medical examiners established that Panettiere died from the ‘toxic effects’ of fentanyl, 4-ANPP, Alprazolam, Methocarbamol, and Quetiapine. Officials verified there were no signs of physical trauma. While the coroner promptly classified the incident as an accidental overdose, local law enforcement alongside the Drug Enforcement Administration sustained their inquiries to ensure all factors were examined, noting previously that a preliminary probe had ‘not indicated any signs of foul play or suspicious circumstances’.

Addressing Speculation and A Legacy on Screen
In September, following the initial toxicological releases, a representative for Hayden Panettiere issued a statement urging the public and media outlets to avoid unsubstantiated rumors. In the statement shared in September, the rep said: “As reported yesterday by the Greenville County Coroner’s Office, Hayden’s death remains under investigation pending the completion of toxicology results, despite reports from some outlets stating otherwise. Recent reports attributed to unnamed sources are unverified hearsay and have attributed to conflicting information that continues to circulate. While we are all eager to find closure and better understand the circumstances surrounding her passing, we must remain patient and allow the investigative process to unfold.”
Panettiere spent nearly her entire life working in entertainment, first appearing in television commercials at 11 months old before joining the cast of the daytime soap One Life to Live at age four. At age nine, she voiced Princess Dot in Pixar’s A Bug’s Life, securing both a Grammy and Young Artist Award nomination. She rose to international stardom playing cheerleader Claire Bennet on NBC’s supernatural drama Heroes and later earned critical acclaim and multiple award nominations starring as Juliette Barnes across six seasons of Nashville. Her film credits included major roles in Remember the Titans, Raising Helen, and Scream 4.
Panettiere is survived by her 11-year-old daughter, Kaya, whom she shared with her former fiancé, former world heavyweight champion boxer Wladimir Klitschko. Prior to her death, Panettiere openly addressed her battles with addiction and postpartum depression, topics she detailed thoroughly in a candid memoir published in May, just months before her passing.
Why This Matters
