So it's about 700,000 to 800,000 genetic markers across the genome.

And then it goes to our bioinformaticists, our scientists.

Now, because these are degraded, mixed profiles,

contaminated samples.

These are not like if you spit in the tube and you have this perfect DNA sample.

These are non-optimal samples.

And so we need something called bioinformatics, which we have an amazing scientist, Dr. Ellen Gratak and Dr. Ellen Katie, sorry, Dr. Janet Katie, it's Parabon,

that work with that degraded DNA to try to repair it and make it as similar to a file as if you and I were to spit in a tube and mail it in.

Once we have that, we upload it to GEDmatch and or Family Tree DNA.

It's compared against all the people there that are opted into law enforcement matching, and we get a list of matches.

Now, those matches are typically going to be really distant relatives.

And that's because these are really small databases we're working with.

So the chance of a close relative of a suspect are very small.

So we're lucky if we get a second cousin or a few second cousins, sometimes closer, but mostly we're working with third, fourth, fifth, sixth cousins and beyond.

And we can predict what the likely relationships are based on how much DNA someone is sharing with that unknown person.

Okay.

And it's somebody famous.

So there's a little bit more efficient way to do it, which is I'll say, okay, who's not, who's, I've got the list of who's sharing DNA with the suspect, but who on that list shares DNA with each other?

That's really important.

So it's not just who's sharing with the suspect, but who is sharing with other people on that list?
