‘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 Coroner’s Office," a statement from Greenville police reads.
