So, one of the biggest things so far is that the prosecution plans to call a new witness who is an expert in shooting reconstruction.

And, you know, all these twists and turns, though, they must be really, really hard on the family.

Any idea how they're getting through this?

I mean, this has been incredibly difficult on them, but they remain deeply committed to their father and what they say is their mission of finding justice for him.

Thanks, Marissa.

A fascinating case.

We'll certainly be checking back with you.

Thanks, Lester.
