Crime stories with Nancy Grace.

Two beautiful young girls go out for the afternoon at a public park, a trailhead, so to speak.

They're never seen alive again and even now the search goes on for their killer.

I'm Nancy Grace. This is Crime Stories live at CrimeCon in New Orleans. Welcome everybody.

Of course, I'm talking about the unsolved murders of the two little girls Liberty and Abigail

on that Delphi bridge. Some of my most important guests are all of you here to help put together

the clues left behind and hopefully bring home a killer and put in where he belongs and that is

behind bars. With me, an all-star panel to lead us through the facts that we know, judge Ashley

Wilcott, forensic professor at Jacksonville State University, author of Blood Beneath My Feet,

Joseph Scott Morgan, climalign.com investigative reporter Lee Egan, and now our special guest,

from Delphi. My name is Mike Paddy, Delphi, Indiana. I'm the grandfather of Liberty,

German. And we're here to spread awareness and information about our case that's still

unsolved. We're still chasing the guy who murdered our girls and with events like this and

the support of people like you, we hope to continue to spread the word and spread the information

because there's a guy out there somewhere who murdered our girls and we're out here to catch him.

And thank you for your support. I see even seen some t-shirts from last year, so thank you.

Thank you for your support.
