North Sioux City, SD
State archeologists are investigating some human remains that were found buried along Interstate 29 in Union County.
The South Dakota Attorney General's office says the remains were unearthed by a utility company crew digging in the right of way near Exit 2.
Spokeswoman Sara Rabern on Tuesday said the scene discovered Thursday appeared to be an "old, old grave."
Rabern says the Division of Criminal Investigation secured the area over the weekend, and investigators did not deem the remains to be evidence of a crime.
The scene has been turned over to the South Dakota State Historical Society.
