The Greenville, South Carolina, police department concluded its investigation Wednesday into the death of actress Hayden Panettiere with a finding that it was an accident.

“Based on the Medical Examiner’s determination and the findings of the investigation, Hayden Panettiere’s death has been ruled accidental,” the department said in a statement emailed to NTD, The Epoch Times’s sister publication. “The Greenville Police Department has concluded its investigation.”

The announcement officially closes the local investigation into the actress’s August death in Greenville with no charges having been filed.

Panettiere died from an accidental drug overdose, a coroner determined on Sept. 22. An autopsy showed no signs of trauma that would have contributed to the death, the coroner’s office said.

“The cause of death has been ruled as toxic effects of fentanyl, 4-ANPP, Alprazolam, Methocarbamol, and Quetiapine,” the Greenville County Coroner’s Office said in a statement to NTD.

Fentanyl is an opioid that can cause fatal overdoses. The substance 4-ANPP is used in the manufacture of fentanyl. Alprazolam, also known as Xanax, is a prescription anti-anxiety medication. Methocarbamol is a muscle relaxant, and Quetiapine is a medication used to treat mental health issues.

A Greenville Police Department spokesperson told The Epoch Times via email that the police were aware of the coroner’s report.

“The Coroner’s Office report represents one component of the ongoing investigation,” the spokesperson said at the time.

Panettiere, 36, of California, died in Greenville on Aug. 16. She was found unresponsive inside a residence where she had been temporarily staying. Resuscitation efforts proved unsuccessful. She was pronounced dead after approximately 40 minutes.

“It is with profound sadness that we share the tragic passing of our beloved Hayden,” her family said after the death was announced.

“She was an incredible light and a force of nature who brought immeasurable love and joy to all who knew her—and to the millions who watched her onscreen.”

Authorities said previously that a preliminary investigation produced no signs of foul play or suspicious circumstances, and that an acquaintance of Panettiere had called 911.

Panettiere’s death was first confirmed by her father, Skip Panettiere, in a statement provided to ABC News.

Panettiere left behind an 11-year-old daughter, whom she shared with former partner Wladimir Klitschko, a sports scientist and former professional boxer.

Panettiere started her career as a child star and was best known for her roles as cheerleader Claire Bennet in the TV series “Heroes” and as country singer Juliette Barnes in the drama “Nashville.” Her other credits included “Remember the Titans,” “Scream VI,” and the voice of Dot in “A Bug’s Life.”

The actress had been open about her struggles with alcohol addiction and depression, including after the birth of her daughter in 2014.

In her memoir published this year, titled “This Is Me: A Reckoning,” she wrote about postpartum depression and her decision to give full custody of her daughter to Klitschko.

Panettiere’s daughter, Kaya, has been living with her ex-fiancé Klitschko in Ukraine after she gave him full custody in 2018. Panettiere has spoken of the great relationship she maintained with her daughter and that she FaceTimed with her on a regular basis.
