ATLANTA --- Democratic gubernatorial nominee Roy Barnes' daughter and two granddaughters were injured in a car accident Sunday in Cobb County, with police saying a Porsche traveling above the speed limit crossed into their lane and struck the front of their minivan.
Alison Barnes Salter was taken to Kennestone Hospital on Sunday with injuries that were not life-threatening. Her two daughters -- ages 4 and 7 -- were taken by ambulance to Scottish Rite Hospital, also with injuries that were not life-threatening.
Mario D. Zuniga, of Kennesaw, the 17-year-old driver of the Porsche, was in critical condition Sunday afternoon, according to an official at Atlanta Medical Center. A 16-year-old passenger in Zuniga's car was taken to Kennestone Hospital with injuries that were not life-threatening.
Police say Zuniga swerved into Salter's northbound lane while trying to round a curve. The front of the Porsche collided with the front of Salter's Honda Odyssey.
The investigation is ongoing, police said.
Anna Ruth Williams, a spokeswoman for Barnes' campaign, said the former governor and his wife, Marie, "appreciate the outpouring of thoughts and prayers as their daughter and granddaughters recover from today's accident."
"Their thoughts and prayers also go out to the young men and the families involved in the accident," Williams said.
Salter, an attorney, works at Barnes Law Group, a Marietta law practice, with her father.
