A Dickson County Sheriff’s Office deputy is off the job after being charged with DUI following a recent accident. Sheriff Jeff Bledsoe said Deputy Mark Atchison has been suspended without pay following the May 21 wreck in which the deputy’s car hit a house a few doors down from his home and his subsequent arrest. Bledsoe said Atchison can use any vacation or accumulated leave time during his suspension pending the completion of an internal investigation. Atchison was previously fired by the sheriff’s office following a 2009 wreck of a patrol car after which he allegedly failed a drug test. But he was reinstated following an appeal to the Dickson County Civil Service Board that called into question the validity of the test. Atchison was originally hired during the administration of Sheriff Tom Wall in 2005, then was terminated following the wreck in 2009. The civil service board at first upheld the termination and Atchison had filed for a judicial review of the ruling in which he called into question the chain of custody of his drug test. In September 2010, the civil service board voted 2-1 to reinstate Atchison, leading to the resignation of 20-year board member Joyce Fowlkes. He was rehired in December 2010 by Bledsoe, who was elected to office that year. Atchison was at first assigned to the Dickson County Jail but transferred back to patrol in April 2011. In reviewing the initial accident, Bledsoe said he determined there were “some issues” regarding the drug test, which is required after any on-the-job accident. The sheriff said the county was facing the possibility of expensive litigation and based on the civil service board ruling and recommendation by the county’s attorney he decided to rehire Atchison. Following the latest accident, Bledsoe said his “concern right now is for him and his family.” Bledsoe said Atchison will remain off the job pending the completion of a review of the latest incident and could face disciplinary action that could again include termination.
