A 68-year-old man’s body was found inside a burning home, but police said the victim was shot before the fire.
Now, authorities have arrested his grandson in connection to the case.
An autopsy was completed on Donaldson and officials said they determined Donaldson had been shot.
Investigators believe the fire was started in order to destroy any evidence of the shooting, authorities said.
During the investigation, officials determined the suspect in the case was Donaldson’s grandson and he traveled from Wisconsin to Georgia, but the reason for the trip was not known at this time.
Investigators have not released a possible motive for the killing.
