Actor Hayden Panettiere, 36, dies in August in South Carolina. Multiple reports say an official coroner finding determines her death was caused by an accidental overdose.

The coroner in Greenville County, South Carolina is reported to rule that her death resulted from toxic effects of fentanyl, along with other substances. Sources describe fentanyl as a key drug and add that anti-anxiety medication may also be involved, including references to Xanax and other drugs.

Several outlets also report law-enforcement-related claims about how she took the drugs, including accounts that she may have ingested a single fentanyl-laced pill and that investigators are focused on a possible supplier. Other coverage sticks closely to the coroner’s conclusion and the list of drugs involved, without adopting specific details about a suspect or the exact circumstances beyond the overdose determination. Despite differences in emphasis, all accounts center on the coroner’s determination of an accidental overdose involving fentanyl.
