Three children found human remains while walking in the woods behind a Standish grocery store.
Arenac County Undersheriff Don McIntyre says the kids came across the remains Sunday near the Family Fare Supermarket.
According to McIntyre, authorities found the rest of the remains Monday morning.
He tells MLive.com he's not sure how long the remains were there.
McIntyre says the priority is identifying the remains.
Standish is about 120 miles north of Detroit.
