The Atlanta Journal-Constitution could not reach Sutton for comment.
In 2014, an AJC investigation found that Sutton paid her then-boyfriend $34,000 in public dollars, most of it for political advice during her first two years in office.
That same year, the Ethics Board investigated complaints that Sutton had used her county purchasing card for personal expenses.
While that investigation was pending, DeKalb voters in 2015 approved changes to the Ethics Code that allowed private groups to appoint members to the Ethics Board. Sutton filed a lawsuit saying those changes were unconstitutional, and the investigation of her actions was put on hold.
Barnes left office in 2017.
