No, no one was home.
I try to stay out of politics but here is my understanding of fire investigation in Ga.
Ga has a state fire investigator but I have only seen them a few times. Almost every time was when someone died.
Years ago when I started with the FD as a 16 year old there was a county fire investigator. I only remember meeting him once. I was coming out of a burning house to get some air. We were "carpet suckers" back then. Anyway a car had pulled in the driveway an a man was getting out. I used his hood for a seat. Ha came over to me, wrote something down an said "glad I got here to see this, this one smells electrical to me." (May not be word for word but something like that.) Then he left. I later found out he was the fire investigator an was well known as "Smells Electrical." If I ever heard his real name I do not remember it. This explained some things for me. A few years before, 3 homes on family property were burned by someone but the report on all said electrical even though one had no power at all.
The state guys we have now are smart an I enjoy watching them work but they are coming 3 hours from Atlanta I think an there is some kind of rules as to when they actually come out.
