The former supervisor of the county’s school resource officer program spent thousands of tax dollars on guns and gadgets he kept after his retirement in February and only returned after an investigation into the purchases was launched by law enforcement. Eight weapons, including two rifles and a shotgun, worth roughly $4,000 were purchased with school system money though none of the officers ever received the firearms and the superintendent said the purchases were not approved. All of the purchases were made between November 2013 and October 2015 on a Hall County Board of Education credit card and were registered under the name of Lt. Earl Roach, who retired Feb. 29, according to a Sheriff’s Office internal affairs report obtained by The Times.
