About 4 p.m., a Kia Sportage traveling west on Highway 140 near Big Oak Road crossed the center line, striking a Buick LeSabre traveling east head-on.
GSP Public Information Officer Gordy Wright said three people were pronounced dead at the scene and a fourth victim died at Erlanger Medical Center in Chattanooga. The fourth victim had been airlifted from the Food Lion parking lot in Adairsville.
Bartow County Coroner Joel Guyton identified the victims as: Ralph Ivie, 56, of Summerville, the driver of the Kia; and J.R. Tucker, 81, of Trion, driving the Buick; and Margaret Crews, 81, of Griffin, a passenger in the Buick; and Elevagene Tucker, 79, of Trion, who was Tucker's wife and died at Erlanger.
Earlier reports said Elevagene Tucker died en route to the hospital but Guyton said she passed away shortly after arriving at Erlanger.
The accident closed all lanes of Highway 140 for several hours, reopening about 7 p.m.
According to Bartow County Fire Department Station 10, the weather was not a factor.
