Hayden Panettiere’s Death Investigation Results Revealed, Case Closed

The police investigation into Hayden Panettiere‘s death has ended.

Two months after the Nashville alum died at 36 in a South Carolina apartment, the Greenville Police Department confirmed that authorities have closed her case.

“Based on the Medical Examiner’s determination and the findings of the investigation, Hayden Panettiere’s death has been ruled accidental,” police said in a statement to E! News Oct. 28. “The Greenville Police Department has concluded its investigation.”

The Greenville County Coroner’s Office previously determined that Panettiere died from “toxic effects” of fentanyl and four other substances, with officials ruling her manner of death to be an accident.

In a coroner’s report, the medical examiner stated that other substances found in her system included 4-ANPP—a chemical compound often found in illicitly manufactured fentanyl—as well as anti-anxiety medication Alprazolam, muscle relaxer Methocarbamol and Quetiapine, a prescription drug commonly used to treat depression, schizophrenia or bipolar disorder.

Prior to her death, Panettiere was open about her struggles with addiction, including how it was exacerbated when she experienced postpartum depression following the 2014 birth of her and ex Wladimir Klitschko‘s daughter Kaya.
