A tractor trailer was involved in the wreck. Its driver was not injured, nor was the driver of a Lexus that collided with the tractor trailer.

After hitting the tractor trailer, the Lexus slammed into a pickup truck, which flipped several times. Its driver, 50-year-old Enio Tejada of Lawrenceville, was taken to WellStar Kennestone Hospital with non-life-threatening injuries. Tejada's passenger was pronounced dead at the scene; his name has not been released, pending notification of his family.
