WINONA, Minn. – You never what you’ll find at the bluff-top Garvin Heights lookout the morning after. The usual dregs of partying: Empty beer cans, cheap wine bottles, marijuana stubs, drippy condoms. This time was different. Police were called about 9:26 a.m. about a sweatshirt that the caller believed was covered in blood. Not so, it turned out. Officers took one whiff. It wasn’t blood but vomit. They took it to he station house for destruction per protocol.
