Lester Holt

Last summer, 10 years after her disappearance, her former boyfriend, Brooks Houck, was convicted of her murder.

Rachel, you've been covering this case for some time now.

What's the latest on this one?

What's their basis for an appeal?

Now, the jury would obviously disagree that there wasn't enough evidence to convict.

So what's next in the appellate process?

Okay, let's move on.

For our final story, we're heading to Utah, where trial preparation is in full swing for Corey Richens.

That's the mom of three who wrote a children's book about grief before being arrested for her husband Eric's murder.

Prosecutors say she laced his drink with a lethal dose of fentanyl because she wanted his life insurance payout.

Jury selection is set to begin for Richens' trial on February 10th, and she's pleaded not guilty to aggravated murder, among other charges.

What's the latest on this one?

We have some of that message, which was cited in court filings.

Rachel, could you read that for us?

We asked prosecutors for comment.

They told us, quote, We will be responding non-publicly with the court, as is appropriate this close to jury selection.

All right.

Lots going on.

Rachel, thanks for the updates.

Well, for our final story this week, we wanted to talk about something we've been seeing a lot of recently.
