Wis. (WLAX/WEUX) – The one-month mark is quickly approaching in the search to find a missing Winona woman, Madeline Kingsbury. The Winona Police Department and Winona Emergency Manager are making new requests to property owners in Winona and Fillmore counties.

Investigators are asking property owners in these counties to report old wells from before 1925, old homesteads, windmills, or windmill bases.

Investigators are also asking people to report any sinkholes that are accessible by car. Authorities said this information is not available in records and could lead to new searches.
