Hayden Panettiere's Autopsy Showed 'No Signs of Trauma' After Suspected Overdose, Coroner Reports

The Greenville Coroner's Office found "no signs of trauma" in Hayden Panettiere's death.

The 36-year-old was declared dead at an apartment complex in Greenville, S.C., with 911 dispatchers making mention of "cardiac arrest" and a potential "overdose."

Preliminary reports suggested there had been no signs of foul play after she seemingly traveled to the East Coast from Los Angeles, Calif., with her allegedly abusive on-again, off-again boyfriend Brian Hickerson.

Less than 24 hours after her death, the Greenville County Coroner’s Office and Coroner Mike Ellis released an autopsy report.

"An autopsy was completed today. At autopsy, no signs of trauma were discovered that would have contributed to the death," read the statement. "The cause and manner of death remain pending further investigation and the completion of additional studies. This investigation remains active and ongoing. No further details are available for release at this time."

Hickerson was jailed in 2021 for 45 days after multiple abuse charges were laid against him by Panettiere. He was arrested multiple times throughout their relationship from 2018 to 2022 for alleged physical altercations.

They broke up for good in 2022 after he was accused of starting a physical fight with her outside of a Los Angeles, Calif., bar.

The statement also gave more details about the police response after an acquaintance found the actress and called 911.

"First responders and Emergency Medical Services arrived on scene and located a female in cardiac arrest," the statement added. "EMS personnel initiated advanced cardiac life support measures; however, resuscitation efforts were unsuccessful."

"The individual was pronounced deceased at 2:32 p.m.," they concluded.

Police stated that the star was "found unresponsive inside the residence, where she had been temporarily staying." Neighbors alleged the apartment was an Airbnb rental.

It is unclear why the actress was in the southern state or who she was with at the time of her death.

According to TMZ, Narcan — a brand-name naloxone used to reverse the effects of an opioid overdose — was found on a mattress in the apartment where Panettiere passed away.

The actress has been open about her struggles with addiction in the past, even spending eight months at a rehabilitation facility to treat her alcohol issues in 2020.

The star's death was announced by her father, Skip Panettiere, hours after first responders declared her dead.

“It is with profound sadness that we share the tragic passing of our beloved Hayden,” he said in a statement to various media outlets. “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."
