Authorities in eastern Missouri are trying to identify human remains found in a rural area.

KTVI-TV reported Tuesday that the skeletal remains appeared to have been in a rural area of Washington County for a long time, possibly years.

The remains were found over the weekend in the eastern Missouri county. Sheriff Zach Jacobsen said the remains were sent to a forensic pathologist for investigation.

Authorities have not determined the cause of death or whether foul play was suspected.
