Hey, Anne-Marie, it's great to see you.

You know, it's been more than three years for these victims' families.

And during sentencings, I always think about how difficult this is for them, but also how strong they have to be to be able to be that voice for their loved ones.

During his January trial, the Commonwealth argued Brendan and Juliana plotted to kill Christine Banfield by luring Joseph Ryan to the house.

The goal in all of this was to make it look like Joe was the one who stabbed Christine to death.

Brendan and Juliana created online accounts impersonating Christine, including on a fetish site, and ultimately convinced Joe Ryan to come to the Banfield house with a knife under the pretense of a rough sexual encounter.

Brendan entered the bedroom to save his wife and shot Joe in self-defense.

And this was really a case of he said, she said.

Juliana came to the United States from Brazil as an au pair in 2021 and started a relationship with Brendan in 2022.

And she testified that Brendan wanted out of his marriage but felt a divorce was not an option.

So he wanted full custody of his daughter, and Juliana said money was also a concern in all of this.

And remember, Juliana and Brendan lived together in the house, in the bedroom, Anne-Marie, that he used to share with Christine after the killings.

That is, until Juliana was arrested months later, followed by Brendan's arrest.

It is convoluted.

There's so many details and so many twists and turns.

It's hard to wrap your brain around a lot of it.

According to the prosecution and Juliana, Joe was told to come to the house.

This was on February 24th, 2023.

And it was in the early morning and Christine was still in the bedroom.

Brendan then left the house under the pretense of going to work, but he was really at a McDonald's.
