Lester Holt

But then, in a recent head-snapping development, he changed his mind, potentially upending the prosecution's case.

Dateline producer Mike Nardi was in a Florida courtroom last week to get up to speed.

He's here now to tell us what he learned.

Hi, Mike.

Hi, Lester.

Thanks for having me.

All right.

Well, first off, give us a sketch, if you will, of the family dynamics here.

What was the state of Jared and Shanna's relationship, at least to someone looking from the outside in at the time of the murder?

The accused gunman was arrested back in January 2023.

He was a man by the name of Henry Tennant and was a complete stranger to Jared.

How did investigators even connect him to the murder?

Mario Fernandez was arrested a few months after 10, and it took seven months for the police to arrest Shanna.

What do prosecutors say was the motive here?

So, Mike, I'm curious, if they're already divorced, why would she want her husband dead?

Yeah, so that sounds like, as you say, a strong motive for murder, but there's no evidence of any kind of communication tying Shanna directly to Tennant.

She's denied having anything to do with the murder.

Do we know if she ever met Tennant?

Kim Jensen was talking to police before Tenon made his confession, but she certainly seemed to have her doubts about Tenon as the gunman.

Flash forward to this year, Mike.
