MILWAUKEE (AP) —Milwaukee’s mayor says multiple people have been killed in a shooting on the Molson Coors Brewing Co. campus.

Mayor Tom Barrett says the dead include the shooter. He did not give an exact number of people killed in Wednesday’s shooting.

It occurred at a sprawling complex that includes a mix of corporate offices and brewing facilities.

At least 600 people work there. It’s widely known in the Milwaukee area as “Miller Valley,” a reference to the Miller Brewing Co. that is now part of Molson Coors.

WISN-TV in Milwaukee reported Wednesday that as many as 8 people were shot. This, after a Molson Coors employee received an email about an active shooter near one of the buildings.
