An out-of-town police officer shot and killed an individual early Tuesday afternoon in Milwaukee, said two Milwaukee law enforcement sources. Brian Steel, president of the Fraternal Order of Police Capitol City Lodge No. 9, confirmed that Columbus police were involved in a shooting in Milwaukee. The shooting occurred near North 14th and West Vliet Streets outside of the security perimeter for the Republican National Convention, said Milwaukee law enforcement sources, who asked not to be named publicly because they were not authorized to speak publicly about the ongoing investigation. The Journal Sentinel has reporters at the scene.
