José Díaz-Balart

He cooperated with police, but after his first interview, he left the country.

It could raise alarm bells.

Why has this person we're trying to contact left Spain and gone to Portugal?

There was a married Spanish CEO.

Then there was the youngest of the bunch, an engineer.

As police worked their way through Operation Bumble, they were gathering information on another man, one who didn't need a dating app to find Anna.

Police searching for Ana Kanesevic were focused on finding the man in the helmet.

They knew she had been dating men in Spain, but they were also curious about her husband David, who lived in Florida.

Ana's friends said their recent split seemed friendly enough.

But as police continued their investigation, they were hearing something else.

Any of the other interviews you had with people who knew David paint a picture of him in any way?

Sana saw that aspect of David, too, and said it was a factor in their separation.

Did you get a sense that he was...

a controlling person?

The couple turned to therapy to try and salvage their marriage until Ana discovered David had been cheating on her.

She confided in her friends about it.

He had been seeing a Colombian woman he matched with on the dating app Tinder.

And that, to her, was the last straw.

The couple managed the separation themselves without help from attorneys.

But once Ana was living in Spain, David changed his mind about that 50-50 split they had originally agreed to.
