Lester Holt

And says, look, my pop didn't come home last night.

He went out to pick up the mail down the street.

You know, his keys are here, his wallet is here, but no sign of dad.

So they talk to him on the phone for a while.

They send out a police officer, a community resources officer who speaks to him, goes inside the house, is a little bit shocked by his wardrobe, or maybe we should say lack of wardrobe.

He says they were moving and thus things were out of order.

He seemed a little confused.

But as they spent more time and called more officers to this house, the more their spidey sense kind of went off to the fact that, you know, could this be a crime scene?

I'll defer to Dan on this.

The story had been out there for a while, but no one had pieced it all together as we were able to do to really get all the players, all of the key individuals in this and bring them together to tell the story.

And I think it's fair to say, Dan, I think you'll agree, as you watch this hour unfold, the way we put it together,

you can at least understand why some bells of suspicion were ringing.

And I think that was part of what we wanted to do was we were going to give a fair look at this and kind of put people to some extent, you know, in their shoes as they were investigating this in real time.

What made it?

I mean, I think they started off with his behavior, which they thought was odd, and that warranted more police officers coming to the scene.

But there were things like they said there was blood evidence that they had discovered in the home, you know, drops and smears.

But there was also another thing that we haven't talked about here, and that is the cadaver dog.

They called in a cadaver dog that's meant to hit on the scent of human remains.

And they say that it had a positive reaction in that house.

How that occurred, no one can explain because obviously there was no cadaver to be found.
