MUSCATINE, Iowa (KWQC) - The fiancée of one of the six people killed in a shooting spree Monday is remembering a man who brought joy to everyone who knew him. Dakota Whitlow was shot and killed at D.W. Designs on Grandview Avenue, one of three locations where a gunman killed six people in what police call a domestic situation. The gunman later died from a self-inflicted gunshot wound. Audrey Perdue and Dakota Whitlow’s relationship was always in the fast lane.
