DNA is key to this case.

Why is DNA so important?

Because the DNA can prove who was there.

The DNA can help substantiate who was in the house at this time.

The police went in and then two weeks later, find this DNA,

All of a sudden, after two weeks, it's found?

Now, I could see a lot of couch investigators saying that there's something wrong with that.

Why didn't they find this DNA the first time?

Why is it all of a sudden being found, Nancy?

No stone should go unturned, Nancy, in this case.

And so the polygraph should be done as well.

And you're right, you bring up a really good point.

If there's nothing to hide, if there's transparency, then it's really important for people

to give polygraphs.

It's really important for people to give up their DNA, which the family has given their DNA and been ruled out as a suspect.

But going back to the DNA, it's really important that this kind of stuff is key to the case.

Why the DNA is so important, because it can help substantiate who is there.

And DNA can be used in the court of law.

Of course, now the DNA that was found two weeks later could potentially be challenged, but it's really important to look at

What is available?
