Fire investigators and DeKalb County police are hunting for a potential arsonist after a series of fast-moving brush fires broke out across Clarkston overnight. The fires ignited in rapid succession, stretching crews thin as they moved from a university stadium to residential complexes and a local mosque. While DeKalb crews battle suspected arson, South Georgia is suffering through a destructive wildfire season. Two massive blazes have combined to destroy 122 homes, scorching more than 55,000 acres across the region.
