An investigation continued Tuesday into the death of a Johnstown woman who went missing for eight months before being discovered buried in a shallow grave on a city hillside.

The body of Nancy Giles, 40, was found May 26 – buried two feet down along a hillside trail near Roosevelt Boulevard.

Investigators have acknowledged that the case is considered "highly suspicious," but few details are available because the matter is still in the early investigative stages, Cambria County Coroner Jeff Lees said.

A Mercyhurst University team led by Forensic Anthropologist Dennis Dirkmaat is assisting with the investigation, examining the body for clues to what might have caused the woman's death – and when.

Lees said dental records and a serial number from a medical device that belonged to Giles were used to make a positive identification of the woman nearly two weeks ago.

And it could be some time before additional details can be confirmed, including the cause and manner of the woman's death, he said.

City police and the Cambria County District Attorneys Office are also involved in the investigation.

"We're diligently working to uncover what we can to solve this case," Lees said. "But it will take time."
