Well, that can be done pretty simply by getting their DNA profile and doing a comparison to any developed DNA that we get from that crime scene.

And I really don't see it as a problem.

I think one of the things that you mentioned in the past is we don't have a suspect yet.

So we're not creating DNA.

We cannot create a DNA profile.

Whatever is on that evidence is on there.

We don't even have the suspect's DNA to compare it to.

So once we have that, if there's a match,

No one can say, ah, they somehow planted his DNA.

We didn't have his DNA.

So I really don't see it as a problem.

I work on cold cases all the time where we have DNA that maybe was collected in the 80s or 90s and we're just getting a profile today.

That doesn't mean that we somehow created it.

It's always been there.

We're just developing the DNA profile.

at this time.

So I don't see it as an issue.

That's true, but this is what I think he's talking about is genetic genealogy and SNPs.

SNPs, which is single nucleotide polymorphisms.

So we're looking at single base pair differences.
