Unless he has some militant-type friends who are willing to take the heat for harboring a cop/judge killer, it won't take a very long time (a few days at most) to catch this guy. Since he's already on trial, they've investigated his life and I'm sure they're pretty familiar with his family/friends/associates. They're going to put the squeeze on them, and they'll squeeze hard until he shows up. I don't think anyone he knows will harbor him--just for that reason.
And when they do find him, he will probably force law enforcement to shoot him dead.
IMO, this has already happened - they just have to find him.
I'm sure that they will check his known associates, but there will be some that will still help. I'm sure they will ultimately find him, but it may take a while. It may not. And I feel certain that in the end, he will die for his deeds. Probably quite violently.
Yeah that's the ticket!
Seriously though, this scum should not become a burden on the taxpayers of the great state of Georgia!
