Report: Hayden Panettiere death probe examines fentanyl-laced oxycodone

Officer Matthew Bryan arrived at the Greenville, South Carolina apartment on August 16, 2026. He met Brian Hickerson and Zach Hickerson at the residence. Paramedics were working on Hayden Panettiere, performing CPR. Narcan had already been found in the apartment and administered before emergency crews got there; it had not revived her.

Bryan’s report recorded what he saw of the two men while the efforts continued. “I observed Zach to be very emotional while EMS were working on Hayden. Brian did not become emotional until EMS declared her officially deceased.” A responding officer’s note added that the patient did not seem to have any obvious physical reasons to be unresponsive.

She was declared dead at 2:31 p.m.

Brian Hickerson handed police a bag of medication Hayden was currently on. One report listed nine medications. The names were redacted in the police report. Police found no signs of foul play. The autopsy found no signs of trauma.

Law-enforcement sources say the working theory is that she took a single oxycodone pill the morning of her death. That pill, they say, was allegedly laced with fentanyl. Fentanyl is a synthetic opioid 50 times stronger than heroin. It was developed as a medical pain medication and works by activating the same opioid receptors other pain drugs use, producing sedation and analgesia at clinical doses. Outside controlled settings the same action can slow breathing enough to kill. In illicit form it has been mixed into other drugs and pressed into counterfeit tablets made to look like pharmaceutical oxycodone, so a person can swallow what appears to be a familiar prescription pill and receive a far more powerful opioid instead. Sources caution that everything hinges on the toxicology results. The Greenville County Coroner’s Office has said those results remain pending and could take up to 12 weeks. Official cause and manner of death have not been confirmed.

Sources with knowledge of the case say she had a long-time drug dealer in Los Angeles who supplied black-market prescription drugs, including oxycodone. She allegedly took several of those purchased drugs on a flight from Los Angeles to South Carolina the day before she died. The next morning she took one oxycodone pill.

DEA offices in Los Angeles and South Carolina are conducting the investigation. Agents in Los Angeles are working to piece together her relationship with the alleged dealer and to trace that pill back to him. Brian Hickerson later met with DEA officials as part of the probe. He has not been identified as a suspect. No arrests have been reported.

In a 2023 interview she put the first turn on the record in plain words. “I was the one who checked myself into the first treatment center. I was drowning.” That was 2015, while she was filming Nashville. The memoir This Is Me: A Reckoning, released months before her death, set out the longer account: child stardom, postpartum depression, alcohol and opioids, the pressure of Hollywood. She wrote of substance struggles that began in her teenage years and of the serious consequences that followed from both alcohol and opioids.

The same book turned to Brian Hickerson. Their relationship had been on and off for years. She had met him in 2018 at a West Hollywood restaurant. She wrote of deciding to let go of resentment and try to forgive. In 2020 he was charged with multiple counts of felony abuse. He pleaded no contest to two counts of injuring a spouse or partner, served a short time in jail, and was sentenced to four years of probation plus anger management and Alcoholics Anonymous. Last month a Los Angeles judge denied his request to reduce the convictions to misdemeanors. Of the jail stretch she wrote two sentences that fixed what she had wanted. “I wanted Brian to be in jail just long enough to scare him, but not long enough where'd he become a worse person.” “I needed him to admit his wrongs and change because of them, but I didn't want to traumatize him in an irreversible way.”

What she put on the record about recovery sat beside another public thread she kept returning to that spring: her daughter. In May 2026 she told podcaster Jay Shetty: “I think there’s been this very common misconception that I just gave up my child. That could not be farther from the truth.”

Kaya was born in 2014. She has been living in Europe with her father, Wladimir Klitschko, after a custody decision Panettiere made amid mental health and addiction struggles and later called one of the most painful periods of her life. The girl began living with him full-time when she was two. In the months before her death Panettiere continued to speak warmly about her daughter and said she hoped the memoir would help Kaya understand her experiences while protecting the girl’s privacy. Heroes, Nashville, Ice Princess, and Scream stood as backdrop to that thread.

Klitschko posted on Instagram after she died. “She built an incredible career through immense talent, while also facing the darker sides of a very demanding industry. Nothing will erase the times we shared or the place she had in our lives.”

A representative for Panettiere told Page Six what little could be said while the files stayed open. “The investigation is still ongoing. Law enforcement has not disclosed who they are targeting, but I am told the case is complex. We hope to have more answers soon.”

Agents in Los Angeles were still tracing the pill.
