HARRISBURG, Pa. (WHTM) – Authorities are investigating after the discovery of human remains in Susquehanna Township.

A jawbone was discovered Thursday morning, at around 8 a.m., in an abandoned parking lot at North Front Street and Houser Road. Police searched for additional remains but no other bones were found.

Dauphin County Coroner Graham Hetrick said jawbones are distinct, so it didn’t take him long to verify the bone is human. He said the bone has decomposition, but there is still a lot to be learned from it. He said the person was likely older and had a lot of cavities.

The bone will be examined by a forensic dentist. They will build a DNA profile of the dental records that will be uploaded to a national database, but finding a match isn’t exactly a slam-dunk.

“Who knows, it could be five years from now, somebody puts in dental records, and they say, ‘we’ve got a match,'” Hetrick said.

The discovery came days after a human skull was discovered in a wooded area of West Hanover Township, not far from where Heike Leich went missing more than 12 years ago. The skull was found north of the 7800 block of Fishing Creek Valley Road by outdoorsmen hiking in the area on Sunday, state police said.

“Most of the time they’re animal. This is unusual. In a week, we find two sets of bones and both of them are human,” Hetrick said.

Hetrick said he does not believe the two cases are related.
