Plus, a new podcast series on the murder of Martha Moxley, the Greenwich, Connecticut teen found beaten to death with a golf club 50 years ago.

Welcome back.

Joining me for this week's Roundup is Dateline producer Veronica Mazzaca.

Welcome, Veronica.

Veronica, we're starting off this week in Fairfax County, Virginia, with a trial in a case we've talked a lot about.

This is the trial of former IRS agent Brendan Banfield, who prosecutors say murdered two people so he could be with his lover, the family au pair.

He has pleaded not guilty.

The prosecution's theory involves one of the most elaborate murder plots we've come across, Veronica.

Just remind us of what that plot entailed.

Last week, Veronica, we talked about the bombshell testimony of the au pair, Juliana, Brendan's lover and alleged partner in crime.

She flipped on him before trial and agreed to testify against Brendan in return for reduced charges.

She has pleaded guilty to manslaughter in connection to the death of Joe Ryan, the man they allegedly lured to the house.

We were all a bit surprised that the prosecution put Juliana on the stand, the au pair, so quickly on day one of testimony.

What else did we see after that from the prosecution?

How did the defense counter these findings?

OK, so the defense started calling its first witnesses on Wednesday, including police officers and a digital forensics expert.

We'll report back on what they have to say and be on the lookout for closing statements and a verdict.

For our next story, Veronica, we're heading to South Georgia, where a verdict has been reached in the Susan Embert trial.

This is the case we told you about a few weeks ago involving a woman who was accused of fatally shooting her husband, Jake, and she's accused of staging Jake's death to look like a suicide.

Veronica, this has been a long journey for everyone in this case.
