Skeletal human remains that might be decades old were recovered Wednesday from a sinkhole in eastern Franklin County, Sheriff Pat Melton said.
The state medical examiner's office will now try to determine how long the remains were there, Melton said.
"It appears to be something that's very, very old," Melton said.
The remains were found Tuesday by a farm worker who was mowing a field off Jones Lane near Switzer.
Never miss a local story.
A skull was found about 10 to 12 feet in the sinkhole, and more bones were found below that, Melton said.
It's not known whether the remains were of a man or woman.
"We'll have to wait for a forensics report to come back to see what exactly we're talking about," Melton said.
The state medical examiner's office speculates that it might take weeks to complete a report, Franklin County Coroner Will Harrod said.
Deputy sheriffs, the Franklin County coroner's office and county firefighters were there from about 8 a.m to 3:30 p.m. Wednesday, Melton said.
Photographs posted on the Franklin County sheriff's Facebook page show a backhoe at the site.
It was there "in case we needed to excavate the earth back enough to do an archaeological dig, but that wasn't necessary," Harrod said.
