Milwaukee police late Monday were investigating whether a 20-year-old man who showed up at a hospital with a gunshot wound is the same man who tried to rob an Aldi store and was shot at by a customer.
A man with a shotgun entered the store at N. 76th St. and W. Villard Ave. about 7 p.m., according to a news release from Milwaukee police.
According to the release, as the man began to rob the store a customer fired shots at him, and the man fled empty-handed.
