Listen to Hayden Panettiere 911 call as Brian Hickerson’s brother desperately tries to save actress’ life

Zach Hickerson’s desperate attempts to save actress Hayden Panettiere’s life have been revealed in a a newly released 911 audio dispatch.

A 911 call, obtained by CBS News Wednesday, revealed Brian Hickerson’s brother called authorities in a panic after finding the “Heroes” alum unresponsive in an Airbnb in South Carolina on Aug. 16.

“Oh god, oh my god,” Zach — who said he had just returned from church when he found her — can be heard on the call before the dispatcher asked if Panettiere was breathing. “No, I don’t think so.”

The dispatcher instructed Zach to find a defibrillator, which he was unable to locate. He then confirmed the actress was not breathing.

“OK, we need to start CPR,” the dispatcher told Zach. “I’m going to tell you how to do CPR, OK? We’re gonna start with ventilation first.”

Zach proceeded to perform the life-saving measures on Panettiere until first responders arrived and took over.

The “I Love You Beth Cooper” star was pronounced dead at the scene at 2:32 p.m. local time. She was 36.

Additionally, a police report previously obtained by Page Six revealed Brian, who was involved in an on-again, off-again relationship with Panettiere since 2018, gave officers a “bag of medication” she had been taking.

Page Six confirmed that Panettiere died from the toxic effects of 4-ANPP, fentanyl, methocarbamol, alprazolam and quetiapine.

Her manner of death was ruled an accident, with “no signs of trauma were discovered that would have contributed to the death.”

Hayden’s death was confirmed by her father, Skip Panettiere, via a statement that same day.

“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,” he wrote. “We ask for privacy as our family takes time to process this unimaginable loss.”

Ahead of her death, Hayden was candid about her ongoing addiction to opioids and alcohol, and her journey with postpartum depression.

The “Nashville” alum recalled in 2015 the “really scary” and “painful” experience after she gave birth to her and her then-fiancé Wladimir Klitschko’s now 11-year-old daughter, Kaya.

“There’s a lot of misunderstanding — there’s a lot of people out there that think it’s not real, that’s it not true, that it’s something that’s made up in their minds, that, ‘Oh, it’s hormones,’” she shared on a vulnerable episode of “Live with Kelly and Michael.”

“They brush it off. It’s something that’s completely uncontrollable. It’s really painful and it’s really scary and women need a lot of support.”

Ultimately, Hayden’s battle with addiction led to her engagement with Klitschko ending in 2018, and her giving full custody of Kaya to her ex.

“It was the hardest thing I ever had to do,” Hayden said in 2022, per People. “But I wanted to be a good mom to her — and sometimes that means letting them go.”

According to a Greenville County Coroner’s Office obtained by Page Six, Hayden had allegedly overdosed and entered rehab before she died.
