So from Vn_survivor_67-68's post it would appear that a failure to match all 13 is generally a failure to extract some of the 13 from the "tissue" which makes the "tissue" compromised.

This makes more sense to me than successfully extracting all 13 from the "tissue" and then having some of them mismatch. It seems to me that if even there is one mismatch from a successful extraction of 13 then that would be the basis for an overall "no match".

That's what I read yesterday. Without 13 matches, the "supposed perp" is excluded. It is not him.

I'm not sure how DNA computes but guessing that say "8" of the boys would match 5 markers....as in a general population data base??
