What We Know After Police Closed the Hayden Panettiere Death Case

Police in Greenville, South Carolina, announced Wednesday that they have closed their investigation into the death of actor Hayden Panettiere and that her death has been ruled accidental. The department said its conclusion rests on the medical examiner's determination and its own investigative findings.

Panettiere was 36. The coroner's office said in September that she died of an accidental drug overdose that included fentanyl. Here is what officials and published records say.

What did Greenville police announce?

A department representative confirmed the ruling to Page Six and to Fox News Digital, and CBS News also reported it. The statement said the death was ruled accidental based on the medical examiner's determination and the findings of the investigation, and that the department had concluded its work.

Page Six noted that the closure comes more than two months after her death. Earlier, police had said there were no signs of foul play or suspicious circumstances, according to CBS News. The Drug Enforcement Administration was among the authorities looking into the circumstances, CBS reported.

What did the coroner find?

The Greenville County Coroner's Office determined in September that Panettiere died from the toxic effects of fentanyl, 4-ANPP, alprazolam, methocarbamol and quetiapine, according to Page Six and Fox News. The coroner's office said there were no signs of trauma, CBS News reported.

A detailed coroner's report obtained by Page Six said investigators later found suspected drugs, prescription medications and drug paraphernalia inside the residence.

What happened on Aug. 16?

According to a coroner's office release obtained by Fox News Digital, a 911 call about a reported cardiac arrest came in at about 1:51 p.m. Emergency medical crews found a woman in cardiac arrest and began advanced cardiac life support, but they could not revive her. She was pronounced dead at 2:32 p.m.

Accounts differ on how to describe the location. CBS News called it a residence where she had been staying, Fox News called it an apartment, and Page Six said it was an Airbnb.

Her on-again, off-again boyfriend, Brian Hickerson, and his brother Zach were with her, according to a police report cited by CBS and Fox. CBS reported that the brothers made the 911 call. The coroner's report obtained by Page Six said one of them gave two doses of Narcan, a medication used to reverse opioid overdoses, before calling 911 and starting CPR.

What has her family said?

According to the coroner's report cited by Page Six, her father, Skip Panettiere, told investigators she had spent two to three weeks at a rehabilitation facility in Malibu, California, and had been released just weeks before she died. He said she had struggled with addiction since her early 20s and that the problems worsened after postpartum depression following the birth of her daughter, Kaya.

A private memorial service was held in Malibu on Sept. 19, Page Six reported. About 150 people attended, including former co-stars Connie Britton and Charles Esten of "Nashville."

Why does it matter?

The ruling formally ends the police inquiry into a death that drew national attention, and it settles the official classification as accidental. The case also underscores how fentanyl can appear alongside other substances in overdose deaths, which is what the coroner's findings in this case describe.

Panettiere was widely known for playing Claire Bennet on "Heroes" and Juliette Barnes on "Nashville," and her film roles included "Remember the Titans" and "Ice Princess." Fox News reported that she is survived by her daughter, Kaya, who was born in 2014 to Panettiere and her former fiancé, boxer Wladimir Klitschko.
