Former Hall County Extension agent Billy Skaggs resigned as chief operating officer of the Georgia Department of Agriculture last week after an internal investigation showed that he drank alcohol, went swimming in some state of undress and damaged a state vehicle during a training seminar last year. Skaggs and Oscar Garrison, head of the Food Safety Division, resigned March 30 after questions surfaced about their behavior at the seminar at the Lake Blackshear Resort and Golf Club near Cordele in September. Both admitted to staying up late and drinking alcohol, but later versions of their stories conflicted with their original interviews, an investigative summary said.
