 slows the process down, eventually the dead body will decay. I talked to one of our funeral directors here in this vicinity of Kalamazoo. I asked him one time if he ever had to get in these DNA cases where they have to exhume the body, and he said he did. I said, what's the oldest body you've ever seen that you had to bring out to take DNA from? He said it was a 20-year-old body.
