And then there's a stoppage. How long does she stop running and she's just in one place? We had as much as four minutes. And then all of a sudden, Molly is now moving on a different road south about 60 miles an hour. Well, we know she can't run that fast. So we knew it had to be in a vehicle.

So while we're looking at cars, one of the agents, Matt George, is staring at the screen and he sees Molly. We reached the end of 385th, and now this is where the cell phone data starts showing us where Molly is suddenly moving at 60 miles an hour down this road.

Police were dealing with dozens, even hundreds of leads. She was supposedly seen down at a rest stop in Missouri or eating tacos in Colorado. It was chasing her tail, you know, chasing red herrings.

Kind of looked at each other one day and thought, I wonder if this is what we're going to be doing for like the next five or six years.

That's my first time in the case. We all started looking at each other like, Holy cow, is this it? Is this the break we needed?

A unique car. It's aftermarket stuff that's put on the car. If you wanted us to go find a Black Malibu, we could find hundreds that all look the same. This one was different.

Yes, and to take it one step further, we decided to pull her partner out of there because he was only engaged with her. What's going to happen to me?

She was supposed to be at work, but she didn't show up for work. So that pushes us back until the prior evening. And the best we could tell was around 7 p.m. she had a text to her mother saying, saying she was going to go for a jog or something and then maybe come over for dinner. So that's your starting point, 7 p.m.?

They basically give us a tour of the house. And they say, look, Molly's wallet's here. All her clothes are still here. We look for kicked-in doors, signs of a scuffle inside the house. The house was exactly the way it was supposed to look.

How'd she know it was Molly? Because she's a hairdresser and she cut Molly's hair and she gave a pretty good description of what Molly was wearing. Black running shorts, a pink sports bra. She said she could see her ponytail bouncing. It was our first real definitive timestamp.

Or was she lying injured beside the road? Ditches in July in Brooklyn are waist to chest high in grass. Corn is 8 to 10 feet high on both sides of the road. So if you wanted to hide something, you wouldn't have to try that hard. You could hide 100 bodies along that road and they'd be hard to find.

We did. Sex offenders along the routes. We were not only talking to the people, we were searching every bit of the property. We'd go into the garden shed, the garages, the rafters of the garage, the basements of the house.

You asked Wayne Chaney to take a polygraph. Yes, we did. It's interesting because he got mad and he ended the polygraph before he finished it. So it didn't look good for him.
