Authorities in Mississippi are intent on identifying the heartless gunman who shot and killed a K-9 officer last week. Floki, a 7-year-old multipurpose Dutch Shepherd trained for tracking and drug detection, was on the job Wednesday, April 1, patrolling the border fence around Marshall County Correctional Facility in Holly Springs when he was struck with a bullet. The shooting is believed to have happened at around 7:45 p.m.
