DEA Joins Investigation Into Hayden Panettiere's Death at 36
The Drug Enforcement Administration has joined the investigation into the death of actor Hayden Panettiere, who died on Sunday night at age 36, according to ABC News.
The DEA is now part of a joint effort with South Carolina's Greenville Police Department and the local coroner's office, TMZ reported on 19 August. Variety confirmed the federal agency's involvement on 20 August. The official cause of death has not yet been determined.
Panettiere was reportedly found unresponsive by a friend, and the 911 call cited possible cardiac arrest, according to TMZ. She was set to celebrate her 37th birthday with her daughter Kaya, the outlet also reported.
A federal drug agency stepping into a local death investigation is unusual but not unprecedented. The DEA typically joins cases where investigators suspect controlled substances may have played a role, though no such determination has been made public in this case.
In her 2026 memoir This Is Me: A Reckoning, Panettiere wrote openly about her years-long struggles with drug and alcohol addiction. The book was published earlier this year.
Panettiere's career began in childhood. She was 11 when Remember the Titans premiered in 2000, and she became a household name as the indestructible cheerleader Claire Bennet on NBC's Heroes, which ran from 2006 to 2010. She later starred as country singer Juliette Barnes on the musical drama Nashville from 2012 to 2018, a role that earned her critical recognition and two Golden Globe nominations.
Tributes from former co-stars have poured in. Jack Coleman, who played her father on Heroes, shared an emotional remembrance on Instagram on Wednesday. Christy Carlson Romano, a fellow former child actor, wrote an essay for Elle in which she remembered Panettiere and compared the trauma of childhood fame to Chronic Traumatic Encephalopathy, the degenerative brain disease linked to repeated head injuries in athletes.
Panettiere is survived by her daughter Kaya, whose father is former professional boxer Wladimir Klitschko.
The investigation remains ongoing. No cause of death has been confirmed, and no further details have been released by the Greenville County Coroner's Office or the DEA.
