And an autopsy determined Adia died from strangulation and blunt force trauma to her head and face.

What a horrific image that must have been.

So let's fast forward to the trial, if we can.

You were in the courtroom for opening statements.

How did the prosecution begin its case?

The prosecution's strategy was a classic connect the dots opening.

They connected digital searches, video, the tank, conduct during the search warrant.

In addition to looking at all the evidence that I've just showed you, you're going to be able to compare the statements that Dale made to the police.

And here's something we didn't know before.

They said that surveillance footage showed Dale gathering welding supplies around the time she had disappeared.

It was also caught on body cam.

According to prosecutors, he was moving his wife's body under the noses of law enforcement who had come to investigate her disappearance.

And you also see that he moves a tank while the police are searching.

What are they saying is the alleged motive?

Prosecutors say that this case centers around money and control.

Dee, according to her children, was done.

Dee had been talking about divorce on and off, but this time she really meant it.

She wanted to sell the trucking business.

She was done with it.

And if that were to happen, they all stood to lose financially.
