WINONA, Minn. — During a traffic stop, the cops were sure that Nathan Brett Styles, 27, had been drinking. He smelled like it. Too, he admitted to being at a bar a half hour earlier. His blood-alcohol content on the spot showed impairment at 0.9%. In the car with Styles was David Frederick Dantzler, also 27, and he had a cold beer open — an open container in a vehicle is a legal violation in Minnesota. Both men were charged. Styles is from Mundelein, Illinois, and Dantzler from Homestead, Florida. The stop was about 12:05 a.m. at Third and Sioux streets on the West Side.
