WINONA, Minn. — A thief cut into a ground-level air-conditioning unit at St. Stanislaus Basilica and stole $200 worth of copper. Although the copper was a small amount, damage to the eight-foot tall chiller was extensive. Experts estimated repairs could be $20,000. The theft was discovered about 11:15 a. m. There was no surveillance camera. This was in the gentrifying East Fourth Street neighborhood.
