This happened in Tucker, Georgia. A grocery store clerk was going about his day when suddenly three armed robbers busted in and tried to take his cash. In the video you can see the clerk do a pretty good job of fighting the thugs off until one gets close enough to perform an execution style shot to the back of the clerks head.
The clerk lived and was able to call for help to get to the hospital where they found gunshot wounds to the hand, arm and head. This guys is incredible.
