“Unfortunately, many questions and concerns have arisen" about the actions of the district attorneys, Carr said Tuesday in a statement. Gregory McMichael told police he and his grown son armed themselves and pursued the young man because they they thought he matched the description of a burglary suspect. Johnson said Glynn County police contacted two of her assistant prosecutors on the day of the shooting, seeking legal advice. Johnson said she could not recall if she had told Carr's office that she enlisted Barnhill's help before recusing herself. On Monday, Carr replaced him with Cobb County District Attorney Joyette M. Holmes, one of only seven black district attorneys in Georgia.
