Stephanie Lavoie

But Stephanie was convinced she would not simply run away.

That the mysterious man in Greece had, in effect, kidnapped her.

I felt so helpless because I just knew and it seemed like no one wanted to listen.

Not until Sergeant Klinger came on to the department.

So this is just part of her file, right?

Yes.

Sergeant Gary Klinger of the Polk County Sheriff's Department had just taken over the missing persons unit when he opened Lindsay's file.

It was two weeks since she disappeared.

He copied Lindsey's computer hard drive and put his team of cyber sleuths to work.

But he really didn't think that a 14-year-old runaway with no passport could get very far.

He kept telling me, don't give up faith.

Klinger was absolutely determined to get Lindsey back.

Coming up, Sergeant Klinger reaches out to Greek police to expose what he believes to be an international internet conspiracy.

And to hunt down the man who lured a child halfway around the world.

He almost killed her.

I walked the floors at night.

I turned the computer on.

in hopes that I'd hear from Lindsey saying, I'm coming home.

In the weeks after her 14-year-old daughter Lindsey disappeared, Stephanie Lavoie was desperate.

Just hoping that I could see that maybe she's on the instant messenger or she's emailed me or something.
