Bryan Schmitt, 48, purposely drove his car to Hamid Jahangard, who died two days later.
The lawyer believed that Jahangard, a real estate investor, had thrown a golf ball on his car in the 2011 Mercedes CLS550, according to the police.
In addition to a murder charges threaten Schmitt offenses and serious injury, said the DA office.
Schmitt will not plead guilty to his indictment on Thursday, his lawyer Don Samuel told CNN.
The deadly incident occurred on the evening of July 30 in the entrance of a Jahangard rental property in the suburb of Atlanta, Sandy Springs, the authorities said. Jahangard waited for the arrival of painters.
