 That was the sound of the chaos minutes after officers were called to the Caron Share homeless shelter to break up a fight just before midnight. The city police chief said one person inside the shelter became combative with officers and refused to listen to their commands. The Polk County Sheriff told WDAY one of his deputies used their taser and mace. Another used a pepper ball gun to try and control the man. However, the chief said that did not work and a city police officer shot and killed the man.
