Before she was involved in the fatal shooting of a black man after a night of protests, Louisville Metro Police Officer Katie Crews mocked a demonstrator on Facebook, The Courier-Journal reported. Crews posted a newspaper photo that showed a woman offering a flower to the glowering officer with the comment: “I hope the pepper balls that she got lit up with a little later on hurt.” She added, “Come back and get ya some more ole girl, I’ll be on the line again tonight.” Officials said they are now investigating the post by Crews, who was put on desk duty Monday after the early-morning shooting of chef David McAtee by law-enforcement officials. Another LMPD officer, Allen Austin, was also put on administrative leave. Meanwhile, FBI Louisville, Kentucky State Police, and the U.S. Attorney’s Office have confirmed they will launch a joint investigation into McAtee’s death. Louisville Metro Police Chief Steve Conrad was fired Monday after it was learned that authorities involved in the shooting didn’t activate body cameras.
