That's a very difficult search for genealogy, but that happened in record time because it was a great group of genealogists that were able to determine who this individual was.

So that's the hope for this case is you get a good solid profile and you're able to get that into the databases.

You're building your trees and you've got a great team of genealogists assisting.

Mixtures of DNA are going to make law enforcement and attorneys very nervous.

So in the DNA world,

Mixtures are everywhere as technology advances the sensitivity increases.

You're going to find mixtures in almost everything.

Even blood stains that used to be single source.

You might get that 1% contributor.

That's going to make it a mixture.

So that being said in this case.

We know Nancy's profile, we know her family's profiles, so there's a lot to work with and basically remove from those mixtures.

Do I think it's going to take a year?

Not at all.

I think that's the law enforcement translation because it's

probably lack of understanding.

So what they've got is probably good mixtures that they have to deal with and they're going to put those out, but it is not going to take a year in my opinion.

When I testify in court, as I just did last week, I inform a jury that the sensitivity is so advanced at this point and the technology is so advanced that when historically, if you would swab a blood stain off of a surface, you're going to get a single source profile, one person, your bleeder.

Now, because that sensitivity has increased, I take a swab, I swab that blood stain, and I'm very likely collecting cells from underneath that blood stain.
