Hayden Panettiere may have taken a single oxycodone pill laced with fentanyl on the morning she died, according to law enforcement sources, as investigators reportedly turn their attention to an alleged Los Angeles drug dealer and the origin of the suspected fatal dose.

The 36-year-old Heroes and Nashville actress died on 16 August after she was found unresponsive and in cardiac arrest at a residence in Greenville, South Carolina. Authorities have not officially determined her cause of death, and toxicology results remain pending.

What Is Fentanyl-Laced Oxy?

Fentanyl-laced oxy generally refers to an illicit pill sold or presented as oxycodone that contains fentanyl, a powerful synthetic opioid.

Oxycodone itself is a prescription opioid used to treat pain. The danger becomes significantly greater when counterfeit versions are manufactured outside the regulated pharmaceutical supply and contain fentanyl without the person taking them necessarily knowing.

The US Drug Enforcement Administration says fake pills are frequently made to resemble legitimate prescription drugs, including oxycodone, but can contain fentanyl or other substances. Fentanyl is approximately 100 times more potent than morphine and 50 times more potent than heroin.

Counterfeit pills can also be difficult to distinguish from genuine medication by appearance alone, making pills obtained outside licensed pharmacies particularly dangerous.

What Can Fentanyl-Laced Oxy Do to the Body?

Both oxycodone and fentanyl are opioids that act on receptors in the brain involved in pain, pleasure and breathing. When fentanyl is unexpectedly present in an illicit oxycodone pill, its potency can sharply increase the risk of a life-threatening overdose.

Too much fentanyl can suppress the brain's drive to breathe, causing breathing to become dangerously slow or stop altogether. As oxygen levels fall, a person can lose consciousness and suffer brain damage, coma or death.

Signs of an opioid overdose can include pinpoint pupils, extreme sleepiness or an inability to wake, slow or stopped breathing, choking or gurgling sounds, and discoloured lips or skin.

Naloxone, commonly sold under the Narcan brand, can rapidly reverse an opioid overdose if administered in time, although multiple doses may sometimes be required when potent opioids such as fentanyl are involved.

Death Probe Focuses on Suspected Pill

TMZ, citing multiple law enforcement sources with knowledge of the investigation, reported that Panettiere had a long-time drug dealer in Los Angeles who allegedly supplied her with black-market prescription drugs, including oxycodone.

Sources claimed Panettiere took several drugs purchased from the alleged dealer while travelling from Los Angeles to South Carolina the day before her death.

Investigators reportedly believe she then took an oxycodone pill on the morning she died and are working on the theory that it contained fentanyl. However, authorities have not confirmed that account through toxicology testing.

An autopsy conducted the day after Panettiere's death found no signs of trauma that contributed to her death, according to the Greenville County Coroner's Office.

Toxicology Results Remain Crucial

Panettiere's boyfriend, Brian Hickerson, was at the residence when she was found. Reports have said Narcan, the brand name for the opioid-overdose reversal drug naloxone, was administered during efforts to revive her.

Hickerson has since met with DEA investigators as part of the ongoing inquiry but has not been named as a suspect.

For now, the fentanyl-laced oxycodone explanation remains a working theory. Toxicology findings are expected to play a central role in determining what substances were in Panettiere's system and establishing her official cause of death.
