And according to prosecutors, that fear of losing financially escalated into violence.

She went home to tell her husband, the defendant, that the marriage was over.

The prosecution's first witnesses were mostly Dee's kids from an earlier marriage.

Why do you think the prosecution wanted the jury to hear from them first?

The first few days were really about painting a picture of the marriage and of Dee's final weekend.

Dee's children described that relationship as fraught with fights.

They said Dia talked about divorce several times before, but this time it was different.

Dee's daughter, Raquel Bach, when she took the stand, she described her mom as a shell of herself that weekend.

And she told jurors that Dee would have never left the house in pajamas or without her makeup or hair done.

So this is something that prosecutors wanted to emphasize.

The prosecutors also showed body cam of Dale talking to sheriff's deputies when they came to investigate Dee's disappearance.

So the jury got to hear Dale in his own words through that.

This isn't the first time she's done this, guys.

The first thing is she's not communicating with anybody.

But the only thing that's really strange, too, is this time...

Prosecutors are pointing to the gap between what Dale told deputies and the digital record, which shows no travel, no phone activity, no financial movement.

So tell me how the defense is fighting back.

So the defense is saying the state's case is built on circumstantial evidence, not proof beyond a reasonable doubt.

They argue there is no direct evidence Dale had committed the murder.

They challenged family members on how they characterized the marriage.
