The car came to rest in a ravine about 100 feet below the interstate.
Peeples was alone in the car. She died on impact.
Troopers that worked the wreck say she was unrestrained when she was extracted from the car.
They say it's possible she could have been distracted at the time of the wreck.
"Based on just the evidence on the scene, there's no evidence of skid marks or braking of any kind or any other indication there was another vehicle involved," said Mississippi Highway Patrol Cpl. Kervin Stewart. "Just appeared the vehicle went straight off the roadway and came to a crash, in the ditch."
The other deadly accident happened around 7:00 a.m. at the intersection of Highway 18 and Springridge Road.
Investigators say a truck hit a SUV causing it to overturn and strike a pole.
