The Georgia State Patrol said a sports car with Ryan Quinton, 27, at the wheel left the roadway and rolled down an embankment Sunday night, WSB-TV, Atlanta, reported. Quinton and Kali Dobson, 25, had just left their wedding reception at the Wheeler House in Ball Ground, a town about 30 miles north of Atlanta.
Dobson, who was not wearing a seat belt, was ejected from the car.
Quinton told police he lost control of the car when he swerved to avoid a dog. He could face criminal charges if tests determine his blood alcohol level was high.
Chris Thomas told WSB he was driving by when he saw Quinton on the side of the road.
"His shirt was all torn up and he was bleeding. He had blood all over his face and blood coming out of his hands and stuff and just looked bad. And it scared me to death," Thomas said.
Thomas said he held Quinton and the two men prayed together. He said he returned to the crash scene Monday in an effort to understand what had happened.
"What should have been the greatest, most beautiful day of their lives is the end of one and what could very well be something hard for this young man to get over. I pray that he will," Thomas said.
