Crisp County Sheriff Donnie Haralson said 26-year-old Corey Dennis and 27-year-old Amin Dennis were being held without bond in the county jail.
Authorities found a badly burned body Wednesday in a burned sport utility vehicle in a field. The identity of that victim has not been released pending identification at the Georgia Bureau of investigation crime lab.
Authorities on Thursday found the body of 36-year-old Harold Reese Jr. in woods near the field.
Haralson said both victims apparently died of gunshot wounds.
Haralson said the Dennis brothers were arrested after authorities received tips.
