DAWSONVILLE — An Atlanta surgeon was killed in Monday night’s plane crash in Dawson County. Authorities say a single-engine plane on its way to DeKalb-Peachtree Airport in Chamblee lost radar and radio contact before crashing in a heavily wooded area on Auraria Road, killing the pilot, identified as John H. Culbertson Jr. of Atlanta. Dawson County Sheriff’s Maj. Tony Wooten said dental and medical records were used to positively identify the 62-year-old, who was chief of plastic surgery at Emory University Hospital Midtown, according to a news release on Emory’s website.
