DEA joins Hayden Panettiere's ongoing death investigation

Key Points:

• The Drug Enforcement Administration (DEA) has joined the investigation into actress Hayden Panettiere’s death, working alongside the Greenville Police Department and coroner’s office, with a possible drug overdose suspected.
• A Narcan device, used to reverse overdoses, was found near where Panettiere died at a South Carolina Airbnb, though it is unclear if it was administered.
• Paramedics responded to a cardiac arrest call and attempted advanced resuscitation efforts, but Panettiere was pronounced dead at 2:32 p.m. local time; she was 36 years old.
• Panettiere was with her on-again, off-again boyfriend Brian Hickerson and his brother at the time of her death; Brian had shown police a bag of medication she had been taking, though the substances remain unidentified.
• Panettiere had a history of substance abuse and chronic pain, had openly discussed her struggles with addiction, and had previously given up custody of her daughter due to these issues; her autopsy showed no signs of trauma, and the official cause of death is pending.
