A goodbye, on the family’s terms. Friends, relatives and former colleagues of Hayden Panettiere are gathering on Saturday, Sept. 19, for a private celebration of life at a church in Malibu, Calif.
About 150 people are expected. Three names are missing from the list: her mother, Lesley Vogel; her on-and-off boyfriend, Brian Hickerson; and his brother, Zach Hickerson.
Her father, Skip Panettiere, is expected to attend. Malibu was chosen for her love of the ocean and of whales, a cause she campaigned for publicly for years.
Why weren’t Hayden Panettiere’s mom and Brian Hickerson invited?
The family hasn’t given a reason publicly. What’s on the record explains the distance with both.
Vogel and her daughter were estranged in the last months of Panettiere’s life. Vogel has said that about a year before the death, she went to stay with her daughter because she was worried about Hickerson.
On the advice of her therapist, Vogel said, she then told her daughter she would not be in her life as long as Hickerson was. That was the break.
She knew that Brian was toxic, and she knew she had to get him out of her life.

Panettiere had her own account. Vogel was also her manager when she was a child actor, and Panettiere had publicly accused her mother of pushing her to work to pay for the family’s lifestyle. Her memoir, This Is Me: A Reckoning, came out in May.
What happened with Brian Hickerson?
Hickerson, who dated Panettiere on and off since 2018, was with her in the Greenville rental on Aug. 16 when she was found unresponsive. His brother was there, too.
In 2021, Hickerson pleaded no contest to two felony counts of injury to a spouse or girlfriend. The victim was Panettiere.
He has not been charged in connection with her death, and police have not named him a suspect. His attorney said in a statement that “it’s important to allow [the] investigation to proceed. As has been publicly reported, police confirmed there were no signs of foul play.”
Sources close to the brothers say they understand why they weren’t invited and aren’t contesting it, according to Hola! USA.
How did Hayden Panettiere die?
The Greenville County coroner’s office ruled on Sept. 22 that Panettiere’s death was an accident. The autopsy found no signs of trauma.
She was found in cardiac arrest at a home in Greenville, S.C., on the afternoon of Aug. 16 and was pronounced dead at the scene. She was 36. Greenville police led the case, with the Drug Enforcement Administration assisting.
The cause of death was the toxic effects of fentanyl, 4-ANPP, Alprazolam, Methocarbamol, and Quetiapine. The manner of death is accidental.
— Greenville County Coroner’s Office
A ruling that combines five substances is how a coroner explains a death where no single drug alone would have been fatal.
Fentanyl and 4-ANPP, a byproduct of illicit fentanyl production, depress breathing. Alprazolam, a benzodiazepine, and quetiapine, an antipsychotic, add to that effect; methocarbamol is a muscle relaxant. Stacked together, they can slow or stop breathing even when each dose looks survivable alone.
“Accidental” is a legal category, not a comment on how she obtained the drugs. It means the coroner found no evidence the overdose was intentional — the alternative rulings are natural, suicide, homicide or undetermined.
TMZ had reported that investigators believed she took black-market oxycodone laced with fentanyl. The toxicology results are consistent with that account, though the coroner’s report does not name oxycodone among the five substances listed.
Who was Hayden Panettiere?
A working actor since she was a baby. She played cheerleader Claire Bennet on NBC’s Heroes and country singer Juliette Barnes on ABC’s Nashville, which earned her two Golden Globe nominations.
She had a daughter, Kaya, now 11, with former fiancé Wladimir Klitschko. Kaya has lived with her father since 2018.

The take
Five drugs on a toxicology report reads like more evidence of wrongdoing than one. It’s the opposite: it’s how a coroner accounts for a death that no single substance, at the dose found, would fully explain.
Nothing in the ruling changes Hickerson’s legal status — he hasn’t been charged, and police haven’t named him a suspect — because “accidental” describes how the drugs interacted, not who provided them.
