If you need to hide a body, the best way to do this is to remove the hands and teeth to prevent identification (If they can’t identify the body, they can’t possibly link the victim to you since they don’t know who they are) and dispose of them elsewhere. You can also pour yogurt in the anus to help speed up the decomposition process further preventing identification. If you must bury the body, make sure you bury them vertically, as aerial searches will scan for disturbed ground about 6’ or so long. Also, bury a dead animal about 1-2 feet on top of the body so when cadaver dogs will alert, they will find the dead animal and the searchers will asume it was a false positive and move on.
