Hayden Panettiere's Death: Neighbor Recalls 'Jarring' Moments After Actress Was Found Dead at South Carolina Complex From Suspected Overdose

A neighbor in the South Carolina apartment complex where Hayden Panettiere died has spoken out about the chaos that ensued in the community after her death.

The 36-year-old was found at a loft apartment in Greenville, S.C., after an acquaintance called 911 reporting an "unresponsive female" on the afternoon of Sunday, August 16.

"I was shocked, as I’m sure everyone in Greenville was, to find out she was here," the anonymous neighbor told Page Six. "I don’t know that she was there long, and I’m not sure she even ever left the apartment.”

According to Greenville Online, the loft was part of a renovated old mill facility called the Judson Mill Lofts, just two miles from the city's downtown area.

“I can only speak for myself, but you know, I never saw her [and] I haven’t spoken to anyone else that said they have,” the neighbor added.

Police reports stated that there were "no signs of foul play" as they investigate her death. Dispatch audio of the first-responder response made mention of "cardiac arrest" and a suspected "overdose." The Heroes star had struggled with her mental health and addiction for years.

"The apartment complex has sent out a couple of messages saying it wasn’t anything criminal and that there’s no reason for anyone to be scared or anything like that," the person continued.

It's unclear why Panettiere had traveled to South Carolina. The Nashville star was previously spotted boarding a flight out of Los Angeles, Calif., with her on-off partner Brian Hickerson.

Hickerson is originally from South Carolina and has family in the area. Sources confirmed that the loft where Panettiere was found was an Airbnb. It is unclear who she was with at the time.

"It’s still kind of jarring to hear that someone of her stature was here and then that tragically happened to her," the neighbor noted.

According to police statements, the case is under investigation by the Greenville Police Department in conjunction with the Greenville County Coroner's Office.

The neighbor recalled seeing police in and out of the area between noon and 8 p.m. on Sunday. Officials appeared "in shock" and silently moved throughout the area with their "heads down."

"The coroner vehicle showed up, and of course, I knew then that there was a death,” they continued. "Then woke up this morning to hear that it was Hayden, which is just still shocking."

The actress' father, Skip Panettiere, announced her death on the evening of August 16.

"It is with profound sadness that we share the tragic passing of our beloved Hayden," he told ABC News. "She was an incredible light and a force of nature who brought immeasurable love and joy to all who knew her – and to the millions who watched her on screen.
