Prosecutors in Henry County charged Brian Feltman with murder and feticide.
Police said Feltman, whom they believe had been drinking, had gotten into an agreement with Meghann Pope, who was four months pregnant with his child.
Pope left their home on Golf View Crossing in the Heron Bay subdivision in Locust Grove around 6:30 a.m. Sunday and Feltman went looking for her in his truck.
It is believed he then intentionally ran her over with his vehicle.
Police said Pope had initially told them he found Pope lying in the roadway leading them to believe someone else had struck her with their vehicle.
