Mar. 14—BLACK RIVER FALLS — A death investigation has been launched in Jackson County after human remains were found at a residence in the town of Manchester, authorities say.

The death may be the result of foul play, authorities said.

According to Jackson County Sheriff Duane Waldera:

A deputy took the woman's statement and entered the individual as a missing person.
