(WSB Radio) An Atlanta man and his teenage son who were apparently the victims of road rage survived a fiery crash in south Georgia that killed four members of a Kentucky family. 

50-year-old Douglas Jones and 16-year-old Quinton Jones suffered only minor injuries after a car forced them to stop early Thursday morning in the southbound lanes of I-75 in Lowndes County.  Both vehicles were then hit by a Penske rental truck.  The Lowndes County Sheriff's Department says Mr. Jonmes was actually on the phone with a 911 operator when the collision occurred.

Upon impact, the truck and the Kentucky family's car caught fire.  Witnesses got the driver out, but a woman in the passenger seat and her two daughters in the backseat perished in the flames.  That driver was later pronounced dead at a local hospital. 

The driver and the passenger in the rental truck were not hurt.

The accident, which ahppened in the southbound lanes of the interstate near mile markers 16, occurred just after 2 o'clock Thursday morning.  The southbound lanes of I-75 didn't reopen until after 8am.

The fatalities have been identified as 40-year-old Jerome Roberts, 41-year-old Cheryl Collins, 29-year-old Mahronda Collins and 11-year-old August Roberts, all of Midway, Kentucky.  The bodies are being sent to the GBI Crime Lab in Decatur for autopsies and to determine if alcohol or drugs were in the dead driver's system.

In its incident report, the Georgia State Patrol lists Jerome Roberts as the at-fault driver.
