If sample degradation prevented an accurate comparison, why would they release a finding at all? I know Maternity should be a certain match. But, here it is not matching; yet, the investigators are taking the action to test against the fathers side. This makes sense if Degradation prevented an accurate comparison; yet, they did compare and released a finding. Maybe they did release the 1/9000 information to the family with a subtext about degradation issue and we have not been given that information.
It is matching, it's just not matching with as much certainty as they would like. Matching DNA from an unknown person to a known person does not yield a yes/no answer; it yields a probability. If they would expect the markers that they were able to measure to be present in 1 out of every 9000 people, that is still pretty remarkable. Think about how few 9000 people there are in the US. It isn't like they said 1 out of every 2 people have these markers.
