An Alabama driver and her passenger were killed in a wreck early Sunday morning in DeKalb County.

DeKalb police Capt. Stephen Fore identified the two as driver Elise Word, 25, of Birmingham, Ala., and Denerra Patterson, also 25, of the Birmingham suburb of Docena, Ala.

The accident occurred around 5 a.m. on Stone Mountain Highway near Mountain Industrial Boulvard, when the white car the pair was in flipped and hit a wire guardrail, Channel 2 Action News reported. The car, which was traveling eastbound, wound up on the westbound side of the median, according to police.

Word was ejected from the car.

DeKalb police Lt. Charles Barkett told Channel 2 that the car flipped several times, and speed may have been a factor in the accident.

The vehicle crashed into an SUV, but that driver was uninjured, Channel 2 said.

The accident shut down all eastbound lanes of Stone Mountain Highway — also known as Highway 78 — and closed two westbound lanes for nearly four hours, Channel 2 reported.
