CHESTERFIELD, MO (KTVI) – Possible human remains were uncovered at a Chesterfield construction site.

In spite of the police tape and police cars there, authorities told Fox 2 it was not a crime scene.

The site is on Wild Horse Creek Road in an area known for Native American artifacts.

It's a magnet for you might call "amateur archaeologists".

One of them called in quite a find Sunday night, the Chesterfield City Administrator said.

Work had been moving right along at the intersection of Wild Horse Creek and Deep Forest for the new

Arbors at Wilmas Farm: a close to 50 acre site with 47 new houses planned.

Monday came the police tape, police cars, and a forensic anthropologist from the St. Louis County Medical Examiner’s Office.

“It’s a little too close for comfort sometimes,” laughed neighbor, Cathi Vessell. “It’s always been farmland. But anytime they plow, people come out who know this area and know there’s arrowheads or other artifacts there apparently that they’re always searching for.”

Small dig sites dot neighboring properties.

While the heavy equipment was idle over the weekend, someone scavenging for artifacts found more than arrowheads, a city official said.

The Medical Examiner’s Office confirmed the recovery of some type of urn. There were also two bones that appeared to be hundreds of years old, the Chesterfield City Administrator said.

Neither police nor the forensic anthropologist at the scene would say whether they removed anything for further examination, Monday.

For now at least, “grading” work at the site continues.

“I guess I’m not real surprised because we’ve always thought there was more out there than just arrowheads,” Vessell said.

Authorities were waiting on a final determination from the Medical Examiner before deciding on possible further excavation for more remains.

The developer warned trespassers to stay off the property.

There's a list of know Native American sites in Chesterfield.

This site was not on the list, the City Administrator said.
