So, hopefully, if they weren't initially collected, they're collected now and they should be.

I did have people follow up after the last time I was on your show.

That's the best part about the forensics community.

Everybody's like, hey, I did get DNA off of foliage.

I did get DNA off of this, which is great.

So maybe you'll help solve this, Nancy.

They are dealing with mixtures.

Again, the goal is to find a DNA sample that is going to be suitable to do genealogy.

That's your first hurdle.

So the limitations with forensic genealogy happen to be related mostly on the front end with this type of scenario.

as far as mixtures go.

So if they have a complex mixture, three, four contributors, that's going to be something that they have to overcome with genealogy, which is definitely a limitation.

Let's assume they develop a profile suitable for genealogy.

Next, you've got to figure out starting the tree building.

You've got to start getting the sample into databases.

You're only as good as who's in your database, how many people

in your database and working from there.

Then you have the populations.

If you have a Hispanic population, a Hispanic genealogy search that you're going to have to do, maybe that's going to put in some additional hurdles into your search.

So, you know, I always highlight the successes of the cases like the Rachel Marin case, you know, sad, tragic murder case where her perpetrator was
