ATLANTA — University of Georgia students and employees are devastated at the loss of four female students killed in a horrific, high-speed car crash that left another student critically injured, the school's president said at a somber Thursday briefing. The wreck happened when two cars, one northbound and the other southbound, collided around 9 p.m. Wednesday on Georgia State Route 15 south of the Athens campus, Oconee County Sheriff Scott Berry said. All five students were in a Toyota Camry heading north when it veered into the southbound lane, the Georgia State Patrol said in a preliminary report.
