A man and a 6-month-old baby were hospitalized in serious condition after they were hurt Wednesday in a head-on collision in Fairburn. Fairburn Fire Chief Jody Weller said two sedans collided about 11 a.m. at West Campbellton Road and Ga. 92. Seven people were riding in the two cars, but only two were hospitalized. An adult male was transported by ambulance to an area hospital, and the infant boy was taken by helicopter to Children's Healthcare of Atlanta at Egleston. Their names were not reported.
