Actress Hayden Panettiere dies at age 36 in August, and multiple outlets report investigators believe her death results from a single pill containing fentanyl. Reports say authorities are treating the fatal dose as coming from one drug taken on the day she dies, rather than an extended period of drug use.

Several outlets cite law-enforcement sources indicating the pill is described as oxycodone mixed with fentanyl. One account adds that police are reportedly focusing on identifying an alleged dealer, while other reports emphasize the conclusion that a lethal pill is involved. None of the provided summaries include court findings or official determinations within the articles’ text, so the information is presented as reported by sources rather than confirmed by a final official release.

Across the coverage, the main point of agreement is the reported composition of the fatal pill and the idea that only one dose is linked to her death; the differences are in how closely each outlet describes the ongoing investigation and suspects.
