José Díaz-Balart

Agent Montilla wanted to speak with him.

So David was not in Florida, like he told Sana.

He was in Serbia, still more than 1,600 miles away from Ana's apartment.

His attorney went on TV to defend him.

David has nothing to do with this.

He was in another country.

But while his attorney was communicating with police, David was not.

He never called and asked, where is my wife?

Investigators searched for any sign David had been in Spain.

He was not registered as having come in at any airport, any hotel, any place.

David did not show up.

So we asked Serbian police.

Serbian police gave them what appeared to be a lead.

David had rented a car four days before Ana disappeared, a blue Peugeot 308, and crossed the border into Croatia.

And the Serbian police gave us the license plate number of the rental car with which David had left Serbia.

Could David have driven the 25 hours from Serbia to Madrid?

Detective Rodriguez tried to find any trace of David's rental car in Spain.

We asked the Madrid City Hall and the Department of Transportation if that Serbian license plate number had been registered by any of the license plate readers there are throughout Spain, including like that reader, right?

That reader over there.

And the Spanish authorities said that Serbian license plate has never come to Spain.
