German investigators on Thursday carried out raids on dozens of people suspected of posting hate messages about a regional politician from Chancellor Angela Merkel’s party who was killed last year. Walter Luebcke, who led the regional administration in the central Kassel region, was shot on his porch on June 1, 2019, and died later that night. Prosecutors say that he attended an October 2015 town hall event where Luebcke defended the German government’s decision to allow hundreds of thousands of refugees into the country.
