A former Hall County Sheriff’s Office deputy has been charged with stealing county property and violating his oath as an officer. Joel Clifton Ayers, 35, who served in the jail division, was fired Thursday after authorities learned he had stolen a residential metal air handler, which is part of a heating, ventilating and air-conditioning system, according to the sheriff’s office. The part was valued at less than $1,500, spokeswoman Deputy Nicole Bailes said.
