(Fairmont, MN)--Officials are conducting an investigation after a citizen found bones and teeth Tuesday at Sylvania Park in Fairmont.

According to KEYC-TV, Fairmont Police sent the remains to the Ramsey County Medical Examiner’s Office on Wednesday and they were confirmed to be human. The Minnesota Bureau of Criminal Apprehension was also contacted.

Authorities say, due to the perceived age of the remains and the park’s Native American significance, the Minnesota Indian Affairs Council was informed of the findings. Council representatives assessed the site on Thursday and will work with the Minnesota Office of the State Archaeologist, forensic anthropologists, and other experts to determine whether the area is an unrecorded cemetery.

At the Minnesota Indians Affairs Council request, a portion of the park’s southwest corner is closed to the public for the foreseeable future. The public is asked to respect the closure.

Fairmont police say there are no known investigations related to the discovery and no threat to public safety at this time.
