The Dawson County office of the Hall-Dawson District Attorney’s Office no longer has its supervising assistant district attorney.John Wilbanks “will not be returning (to) the district attorney’s office,” District Attorney Lee Darragh said Wednesday afternoon.Darragh would not elaborate on Wilbanks’ departure.“Presently, it would not be appropriate for me to comment further,” Darragh said. “I may issue a press release at a later time, but for now, one would be premature.”Wilbanks was involved in a fight Nov. 19 at a Dairy Queen in Dawson County, in which William Lee Evans, 45, of Jasper was charged with disorderly conduct, according to the Dawson County Sheriff’s Office.Officers responded to reports that Wilbanks had been assaulted, and they pursued Evans, who was riding away from the scene in a car with his son, who was driving, according to an incident report.Evans was taken into custody and charged the next day. His son, Cody Evans, was arrested for traffic violations.Darragh’s only comment on a possible link between the incident and Wilbanks’ departure is that his office will not handle prosecution of the case as it involved a former member of his staff.He said Wilbanks has been with the DA’s office for several years.“I don’t remember when exactly (Wilbanks) started,” Darragh said. ”He had been with the DA’s office on a couple of occasions in the past, as well as during my administration.”Wilbanks could not be reached for comment.Times regional staff writer Michele Hester contributed to this report.
