knock out teeth, drive him somewhere FAR away i mean FAR fucking away, an area where no one is around for miles, dig a grave, pour gasoline all over his body, set him on fire and make sure he burns to a total crips, then smash up teeth, and make sure the fingerprints are burned apart. then smash whats left of his body (it will be weak now) into dust, spread it around so it doesnt look like anything but ash. burn it one more time for good measure, then bury it. the guy will be missing but theyre should be no evidence. oh and get the bullet out of him.
