JACKSON, Ohio (AP) — Authorities are investigating human remains found by children at a property in Ohio, a sheriff’s office said.

A man called the Jackson County Sheriff’s Office on Saturday, saying his children had found human bones at a site near Jackson, roughly 70 miles south of Columbus. The sheriff’s office didn’t share further details about how and where the remains were discovered.

Investigators will examine the remains and conduct DNA analysis to try to determine the person’s identity and cause of death, the sheriff’s office said. They’re also trying to determine how the remains came to be at that location.

Investigators won’t speculate about the identity of the deceased person and won’t release further information until the remains are identified, Sheriff Tedd Frazier said.

The FBI was among the agencies helping with the investigation.
