  You are mistaken on at least one point; you wrote, "If you are hunting and you find a meteorite. You look around and
you find more of the same. You can almost be certain it is from the same fall. " 
 Perhaps you do not have enough experience in hunting meteorites or have never looked at a map of the many of the desert regions showing meteorite finds with various types all within a very close proximity?  Unless the meteorite is broken and the pieces fit back together one cannot say with 100 percent certainty that they are paired just because they were found in close proximity; one can only assume that one might be wrong.
