ORIGINAL STORY: The bodies of two sisters were found Wednesday underneath a bridge in Floyd County, Georgia.
The sisters — 19-year-old Vanita Richardson and 30-year-old Clarice Truvenia Campbell — were found by a Georgia Department of Transportation crew Wednesday at about 11 a.m. under the northbound bridge over the Etowah River near Grizzard Park.
Brian Johnston, the special agent with the Georgia Bureau of Investigation in charge of the case, told local media the bodies looked like they were dropped off the bridge.
The GBI, the Rome Police Department and other local agencies helped at the scene and the bodies were removed by about 3 p.m.
The cause of death is unknown, and the GBI announced Thursday that the case is being investigated as a homicide.
Investigators with the GBI believe Richardson and Campbell were in Richardson's car — a gold 1997 Toyota Corolla — Tuesday night. The car has a Georgia license plate with the number RTJ6295.
Investigators do not know where the vehicle is but believe it could be somewhere in the metro Atlanta area.
The GBI is asking people who might have seen anything suspicious in the area between Tuesday at 10:30 p.m. and 11 a.m. Wednesday to call 1-800-597-TIPS.
