Cammon, 20, faces charges of felony hit-and-run, misdemeanor improper use of the center turn lane and driving with a suspended license, Cobb County Jail records show.
His ex-stepfather, Ben Tidwell, told Channel 2 on Tuesday that Cammon made a mistake and should have stayed to help Dominquez.
“I’m sure he was frightened,” Tidwell said. “He wanted to go home to say goodbye to his family.”
An investigation is ongoing, and additional charges are possible, the release said.
As of Monday morning, he remained in jail on a $100,000 bond, jail records show.
