In the summer of 1999, a young woman in South Carolina disappeared in the middle of the night.

Seven years passed, she was presumed dead. Then a tip came in. A tip that would turn the entire investigation on its head.

You said, I think I found your girl and she's alive, she's in New York. And I said, really?

Yeah, really. According to this tip, this missing woman was now a student at Columbia University.

But the small town detective on the case in South Carolina, he didn't believe it.

So, he kept poking around.

I said, I'm calling about a girl you might know and he said, I wonder when you were going to call?

When my son brought her home, I knew she was trouble.

So, who was this woman? The detective ultimately became convinced that she was a master of deception, a spy who went by many aliases.

She was using genomires, genomory mires, genom formires.

Natalie, I knew her as Natalie.

His investigation drew in the Secret Service, the US Marshals and the Justice Department.

There was a nationwide manhunt, allegations of murder, fraud and espionage swirled.

I mean, there are a lot of people stealing names, but something dealing with espionage spies, that was a fascinating development.

How are we not finding this young girl who stole some identities, but could grieve guys?

We're the federal government here, but we gotta be able to do that.

I need to know. I need to know if she's dead or alive.

I need to just be to know if she's okay or if she's gone.

No one could find her or figure out what she was really after.

I think people think that I had this master plan and I went out and did it.

You know, like it's not fun, right? You're constantly scared.

You have no support. You have no one to talk to.
