Just weeks after our interview, on March 10, 2025, Chelsea says her son Greg was out riding his all-terrain vehicle when he collided with an SUV and died.

He was just 13 years old.

Another tragic loss for a family that had already lost so much.

We're going to start things off with a trigger warning.

Some of the reporting is disturbing, so please listen and watch with care.

So welcome to a special episode of the 48 Hours podcast, Inside the Banfield Trial.

I'm your host, 48 Hours correspondent Anne-Marie Green.

And today we are taking you inside the court case of Brendan Banfield, the former IRS agent charged with the February 2023 stabbing murder of his wife, Christine, and then the fatal shooting of another man, Joseph Ryan, in the Banfield's Northern Virginia home.

Brandon pleaded not guilty to all of the charges, and he maintains that it was Joseph who stabbed his wife while he shot Joseph in self-defense.

This is one of the most talked about trials in the country right now.

It's even sort of being dubbed the au pair affair because Brandon had been having an affair with the family's Brazilian au pair.

Her name is Juliana Perez Magalhaes.

She pleaded guilty to involuntary manslaughter for shooting Joseph Ryan.

Here's prosecutor Jenna Sands describing what she says was Brendan's plan to kill his wife.

And that guy was Joseph Ryan.

So joining me now to discuss this case is 48 Hours producer Michelle Sigona.

Michelle, it's great to see you.

It's great to see you, Emery.

So this is one heck of a case, boy.

I mean, I understand why the entire country has been watching and you've been following this case basically since it started.
