Detective Carter

She's a teenager.

That's unheard of.

We did have hope that somebody new was coming to the case and hopefully they were able to see something that nobody else saw.

I started from scratch.

We took metal detectors where her phone was last seen on Life 360 and attempted to locate it.

We're just going to check that center median.

I really want to find this.

We didn't find the phone.

We just tried.

I spoke to friends.

I spoke to family.

You treat this just like a real homicide case, not just a person just walked away.

Everyone is now considered a suspect at this point.

Throughout those investigations, the police realized that absolutely none of them had any information whatsoever as to Susana's disappearance.

So I asked for another media release to be sent out just to keep her name relevant.

And we had no suspects at that time.

We don't know who's watching.

We needed either someone to come forward with some information or Susanna come home.

If you have information, please call Gwinnett County Police.

And then, within about two weeks or so, we had a break in the case.
