It was very exciting.

They met in Vegas, a professional poker player.

I said he was making good money at it.

A former trapeze artist, she fell for him, but she didn't gamble on this.

I could smell the odor of decay and blood.

Or this, in every turn there was another woman married with a child and a woman in every

city.

What else is he capable of?

A murder?

He had an alibi.

There will be credit card transactions and phone records of me driving from Las Vegas.

But could this little card hold the key?

So that was just a shot in the dark?

Absolutely.

Once he got calculating killer, or was his lifestyle on trial?

He made mistakes that doesn't make him a monster.

Once there, one more card up his sleeve.

He goes back to him thinking I bluffed some of the best.

Thanks for joining us.

I'm Lester Holt.

It was a double murder that was most shocking and puzzling.

There were no witnesses and few clues.
