Hayden Panettiere’s final moments were captured in a frantic 911 call as the brother of her on-and-off boyfriend desperately tried to revive the actress after finding her unconscious at a South Carolina apartment Aug. 16.
“Oh, God, oh, my God — you do like CPR or something?” Zach Hickerson asked the dispatcher in the newly released audio obtained by ABC News and CBS News.
The seven-minute call reveals Hickerson performing CPR on Panettiere while Brian Hickerson administered Narcan.
Panettiere, 36, was found unresponsive at the Greenville residence Aug. 16. Zach told the 911 operator that he had arrived at the apartment after returning from church and discovered his brother and Panettiere inside.

“He woke up, and his girl … she’s unconscious,” Zach said.
The dispatcher asked whether Panettiere was breathing.
“No, I don’t think so,” Zach replied.
The operator then instructed Zach to lay Panettiere flat on her back and begin CPR while emergency crews rushed to the scene.

“OK, we need to start CPR,” the dispatcher said. “I’m going to tell you how to do CPR, OK?”
The operator proceeded to walk Zach through chest compressions and mouth-to-mouth resuscitation.
“We’re going to do this 500 times or until help can arrive,” the dispatcher said, according to ABC News.
Zach continued performing CPR until first responders arrived. Brian reportedly administered Narcan, a medication used to reverse the effects of an opioid overdose.
In a statement to TMZ shortly after Panettiere’s death, Zach said he called 911 after he and Brian tried to wake up the actress.
“When we went in and tried to wake Hayden up, we realized she was unconscious,” he said. “I immediately called 911, and Brian gave her Narcan. We then jointly performed CPR while 911 was on speaker until fire and EMS arrived.”

Fox News learned the Drug Enforcement Administration (DEA) had also been contacted and was assisting with the investigation.
