Earlier this morning, we learned of the tragic passing of Hayden Panettiere, who died in Greenville, South Carolina, over the weekend. Details were scarce, but her father confirmed her death to news outlets, and now we have more details. She was reportedly found unresponsive by a friend of the late actress around 2 PM on Sunday. The cause was a suspected overdose. No signs of foul play were observed in the preliminary stages of the investigation into her death (via NY Post):

Panettiere’s unidentified pal called 911 at 1:51 p.m. Sunday from a Greenville, SC, apartment to report an ā€œunresponsive femaleā€ in ā€œcardiac arrest,ā€ according to dispatch audio obtained by The Post.

Responding paramedics tried to resuscitate the 36-year-old Palisades, NY, native with ā€œadvanced cardiac life support,ā€ which can include breathing tubes, defibrillators, and emergency medication such as IV drugs.

Several minutes later, a different EMT says they are responding to a possible ā€œoverdoseā€ at the same address, and that ā€œCPR is in progress.ā€

The actress was pronounced dead at 2:32 p.m. – just five days before her 37th birthday.

It’s not clear who placed the 911 call. Police revealed Sunday she was found by an ā€œacquaintance,ā€ without revealing their identity.

Panettiere was 36.
