An attorney representing the mother of one of five Georgia Southern University nursing students killed Wednesday in a seven-vehicle crash on Interstate 16 said he has previously sued the trucking company whose driver is responsible for the crash. Joseph A. Fried, of Fried, Rogers, Goldberg LLC of Atlanta, is representing Mary Helen Mehaffrey, the mother of Morgan Bass, of Leesburg, who was killed in the accident along with four others. Fried said in a statement released Friday that he is "quite familiar with the safety history of Total Transportation of Mississippi," which owns the tractor-trailer driven by John Wayne Johnson, 55, of Shreveport, Louisiana.
