The human remains found at a Traverse City construction site last week belonged to the pre-modern era, authorities said.
The discovery was made at around 4:30 p.m. Friday at the Grandview Parkway construction site by construction workers who alerted the police.
Officials secured the site to preserve evidence and recovered the remains. On Tuesday, police posted an update about the finding.
“The bones appear to be from a pre-modern era, suggesting they could be from a time period well before contemporary forensic methods were available,” police said.
Investigators are working with archeologists to determine whether the bones were associated with original fill used for the parkway.
The Traverse City Police Department, state police, Michigan Department of Transportation archeologists and Western Michigan University anthropologists are investigating the find.
