Her mother, Sarah...

has quietly come forward and just sort of was determined to find justice for her daughter.

So I actually went to her home in Central California.

We sat overlooking the ocean and it was beautiful.

And she really talked about her grief over these years.

And it was she who got the lead investigator to promise her not to give up on her daughter's case.

And that is essentially what happened.

You know, she says it never goes away.

It just changes, shape shifts.

And you can tell that her whole life was dedicated to it.

On her property, I walked over to the edge and she said, see these pine trees?

And they're towering pine trees.

She said, I planted them the year Debbie was killed.

And you can see sort of the time and the evolution, but her grief is still there.

We'd been shooting on it for years, essentially, but...

I think for investigators, it was particularly hard because they had a DNA match, thanks to this incredibly brave Jane Doe who came forward.

But that match sort of sat in the banks because they couldn't find the perpetrator based on the DNA match.

And so the investigators will assure you the case never went cold because they kept looking for clues and looking for clues.

But

It took nearly two decades.
