Emergency services were called for a person in "cardiac arrest" before they arrived at Scream star Hayden Panettiere's home on Sunday August 16. It has been reported they responded to the report of an unresponsive woman at Judson Mill Lofts on Easley Bridge Road, South Carolina at 1:51 pm. It has now been confirmed by TMZ the caller indicated she was having heart issues. The 911 call was reportedly made by an unidentified acquaintance. According to dispatch audio obtained by PEOPLE, officials were also heard discussing an overdose and cardiac arrest around the time of Panettieres death.

Police confirmed the 36-year-old mum-of-one died at the scene as they told television station WYFF4: "Upon arrival, medical assistance was administered; however, the individual, later identified as Hayden Panettiere, was pronounced deceased at the scene. The case is under investigation by the Greenville Police Department in conjunction with the Greenville County Coroners Office. The preliminary investigation has not indicated any signs of foul play or suspicious circumstances. An acquaintance of Ms. Panettiere placed the 911 call," they said.

"I wasn't able to bend my toes or lift my foot at all. No one was able to give me a solid answer," she said. It is unknown if this issue is related to her death.

Hayden's father, Skip Panettiere, released a statement via ABC News confirming her death and requesting privacy as the family grapples with their loss.
