Hayden Panettiere previously overdosed, secretly entered rehab weeks before death

Hayden Panettiere allegedly previously overdosed and secretly entered rehab weeks before her drug-related death at an Airbnb in Greenville, South Carolina, on Aug. 16.

On Wednesday, Page Six obtained a more detailed report by the Greenville County Coroner’s Office, which stated that either Brian or Zach Hickerson (the name was redacted) claimed Panettiere “was in a drug rehab facility in Malibu, California, up until a few weeks ago.”

One of the two brothers also claimed the actress “has a long history of drug, alcohol and nitrous oxide abuse” and that he “has had to administer Narcan to the decedent before.”

Narcan is an emergency medication used to reverse opioid overdoses.

According to the report, Panettiere’s father, Skip Panettiere, confirmed that his daughter “had recently been released [from] rehab” in “Malibu.” He said she spent “two or three weeks” at the treatment facility.

Skip explained that Hayden “has struggled with addiction since her early 20s and has been in multiple rehab facilities since that time.”

The grieving dad made sure to stress that her relationship with on-off boyfriend Brian “has been nothing but troubled.”

Skip also noted in the report that Hayden “suffered from postpartum depression after the birth of her daughter,” Kaya, 11, and said her “addiction issues have escalated since then.”

The newly released findings by the coroner’s office, on which TMZ was first to report, included previously unknown details about the day Hayden died.

“A small clear plastic bag of a white powdery substance in a suitcase belonging to the descendent inside of a gray sunglasses case” was discovered on the scene, as was “a cut straw with residue … inside of a small blue colored makeup type bag … inside [a] black bookbag/purse belonging to the descendent.”

Also located inside the apartment was “a medication bottle labeled as Adderall to the descendent on the kitchen table that contained a small, clear plastic bag with blue colored tablets that appeared to possible be pressed pills and a cut straw.”

Per the report, the pills and straws later tested positive for fentanyl.

Investigators also found “multiple prescription bottles on the kitchen table and a small teal blue colored lunchbox with glass vials, prefilled and empty syringes located in the refrigerator.”
