Basically, yes.

In their openings, prosecutors said that Walsh told investigators he didn't know about an extramarital affair, but his Google searches proved otherwise.

He looked up the man Ana was involved with and Googled...

Things like best strategies to divorce for a man.

Andrea, I've never heard anything like this.

The first thing the defense attorney said was that Brian lied to police again and again.

And they also said that, yes, he did go shopping at Lowe's and Home Depot.

And I guess the jurors could assume he did that for the same reason the prosecutor said he did, to buy cleaning supplies and tools to get rid of Ana's body.

It seemed like the defense and prosecution were in agreement about a lot of things.

Except for the most important point.

The defense said Brian absolutely did not kill Anna.

The defense told the story of how they hosted a New Year's Eve dinner with an old friend.

After Anna went to bed, Walsh cleaned up the kitchen and headed upstairs.

And this is what the defense says happened next.

That's right.

The defense attorney said it's something that is not well understood by non-medical professionals and that when it happened to Ana, Brian just flipped out.

I think that's what a lot of people are saying, Andrea.

But the defense said he was desperate.

He feared that somebody would think he'd committed murder, and that's why he tried to hide the body for fear of losing his children.

Did the defense say anything about the alleged affair?
