And we've got verdicts in two big murder trials to catch you up on.

Plus, stadium safety.

Things to think about before you attend your next big event.

On the night before Halloween in 1975, 15-year-old Martha Moxley was murdered, but police failed to make an arrest.

Until, in 2000, her one-time neighbor, Michael Skakel, was arrested.

He was also a cousin of the Kennedys.

The Kennedy connection is the reason that most people know about this case.

But the deeper I dug, the more I came to question everything I thought I knew.

Welcome back.

Joining us for this week's Roundup is Dateline producer Brad Davis.

Welcome to the show, Brad.

Glad to be here, Lester.

All right, well, for our first story, we're off to a Virginia courthouse for the latest in a bizarre double homicide involving a former IRS agent and his family au pair.

Just a few weeks ago, a jury convicted Brendan Banfield for the 2023 murder of both his wife, Christine, and a man by the name of Joe Ryan.

So what's new on this one, Brad?

Well, as you know, Lester, before Brendan's trial, the au pair, a young Brazilian woman by the name of Juliana Perez Magalhães, she pleaded guilty to manslaughter for her role in the murders, and her sentencing was on Friday.

Okay, and before we get to what happened in the sentencing, just remind everyone of what the au pair admitted to doing.

Right.
