The 45-year-old Tomlinson defeated 34-year-old Zeph Baker in a runoff Tuesday by more than a 2-to-1 margin. Turnout for the runoff was 22 percent. She becomes the west Georgia city's first female mayor.
Outgoing Mayor Jim Wetherington says Tomlinson will have an office next to his to prepare for the transition. She takes office Jan. 3.
Tomlinson is an attorney who formerly headed a neighborhood revitalization group.
