A Dawson County sheriff’s employee is on unpaid administrative leave following his arrest over the weekend on suspicion of driving under the influence. Robert Bo Tanner, 25, of Murrayville was taken into custody Saturday night at a residence in downtown Dawsonville. “We received a call into the 911 center advising us that the subject had been drinking and would be traveling to a house inside the city limits in Dawson County,” said sheriff’s Capt. Tony Wooten.
