That was Fairfax County Circuit Judge Penny Ascarate announcing the sentence for former IRS Special Agent Brandon Banfield.

Life in prison without the possibility of parole.

Banfield was found guilty of murdering his wife, Christine, and another man, Joseph Ryan, inside the Banfield's Northern Virginia home in 2023.

The case had been dubbed the Au Pair Affair because of Brendan's relationship with the band feels Brazilian live-in nanny Juliana Perez Magalhães.

Juliana pleaded guilty to involuntary manslaughter for also shooting Joseph Ryan and cooperated with the government testifying against Brendan.

In February, Magalhaes was sentenced to 10 years behind bars.

And on Friday, June 5th, the victim's family members spoke up to honor their loved ones and seek justice.

Welcome to Case by Case.

Hello, Michelle.

I want you to sort of walk us through some of the key moments from the sentencing.

But can you also remind folks of just how we got here?

And key to the Commonwealth's case was the Banfields au pair, Juliana.

Yes.

He mentioned his plan to get rid of her.

So she said he mentioned his plan to get rid of her.

Right.

So let us go back over sort of the details of this murder plan because it's sort of convoluted.

So, you know, Christine obviously is unaware of any of this.
