And this was a critical piece of evidence for them to actually be able to have this when they begin looking for her.

Yeah, police are kind of thinking that she might be a runaway and her sister is insistent that that's not happening.

And then they find evidence of Susana walking home.

So suddenly there's real suspicion that there's something that has happened here, something afoul.

And John, that's what I thought was so touching and also kind of gives me goosebumps really to this moment, thinking about a family's desperation and how a family won't give up when they feel like they know their family member.

They know what she might be capable of or not.

Police were trying to be helpful, but they are also trying to be realistic.

It's a teenager.

But the family would not give up.

Our team sat down with Lieutenant Biggers, who was one of the investigators on Susanna's case.

And he began to kind of take matters into his own hands.

He's trying to help bring her home to her family.

And we showed some of that interview on Friday night, of course.

But here's a bit of it that if you were watching, you didn't get a chance to see on Friday.

Let's take a look.

John, we saw Lieutenant Biggers getting pretty emotional during these interviews.

I mean, this was kind of a mind-boggling case.

I mean, what was that like for you seeing this cop become so emotional in this search?

It takes a while, John, and that's what I think was so fascinating about this story and also so heartbreaking.

I mean, time just kind of dragged on.
