The public information release describes the accident as follows:

The preliminary investigation indicates that a beige 2002 Nissan Pathfinder, operated by Margaret Hamby (58, Marietta), was traveling eastbound on Lost Mountain Rd.

The Nissan veered off its lane and onto the southern grass shoulder for reasons yet to be determined. After briefly returning to the roadway, the Nissan again traveled onto the grass shoulder and collided with a concrete drainage pipe, causing the vehicle to trip and come to an uncontrolled rest on its driver’s side.

Hamby was pronounced dead at the scene by personnel from the Cobb County Medical Examiner’s Office. Her next of kin have been notified.

The collision is under investigation, and anyone with information is asked to contact the Cobb County Police Department STEP Unit at 770-499-3987.
