When Polk County deputies arrived, accompanied by K9 Ace, Bowers fired his gun from the tent. As of the latest update, K9 Ace will likely lose his front left leg and will retire from his heroic six-year career with the Polk County Sheriff’s Office. Polk Sheriff’s Charities, Inc. has an established K9 Fund that will be used to support K9 Ace’s care. A Polk County Sheriff’s Office K9 was shot and injured and is being treated. K9 Ace is the injured K9.
