The Mercer County Coroner has identified the remains found in the Shenango River Reservoir as a white male.

However, further forensic identification will be needed to determine the age of the remains and how long they've been in the water, according to coroner John Libonati.

A cause of death has also yet to be determined and are pending results of forensic toxicology from samples taken during the autopsy.

Due to the condition of the remains and the cause and manner of death, the identity of the deceased is unknown at this time. 

The search has concluded for Thursday, but officers say the search will continue Friday and that they will be searching other areas. 

Hermitage Police called the Clark Volunteer Fire Department to block the Golden Run Wildlife Area entrance along Lake Road near Neshannock Road at 10 p.m. Tuesday.

By sunrise, the fire department had left, but the entrance to the wildlife area was still barricaded with signs reading "emergency ahead." Since then, another fire truck arrived.

Pennsylvania State Police took over the investigation on Wednesday. 

According to a press release by the Mercer County Coroner Office, the remains were found in the water at the reservoir. It is unknown how long the remains were there before they were found. That information will be determined through additional forensic resources and testing.

The Golden Run Wildlife Area is along the lake's southern shore, offering a public boat launch, a hiking trail, and parking.
