Key Discussion Points & Insights

1. Case Background and Shocking Scheme

• The case centers on Brendan Banfield, a former IRS agent, and his Brazilian au pair, Juliana Perez Mahales, who conspired to murder Banfield’s wife, Christine, and frame an innocent man (Joseph Ryan) via an elaborate ruse involving a fetish website.
• According to prosecutors, Banfield and Mahales orchestrated the crime because Banfield wanted to avoid divorce due to money and custody concerns. The plan involved luring a stranger through FetLife.com with an ad posing as Christine, inviting a violent rape fantasy.
  • [01:14–03:24]
• Joseph Ryan, a total stranger, responded to the ad, unaware that he was being set up as the fall guy.

2. Mechanics of the Crime and the Fetish Community

• The co-hosts discuss the logistics and ethical codes of the fetish community, emphasizing how unusual it is for someone to agree to an encounter without an in-person meeting—a protocol Ryan skipped, making the setup possible.
  • [03:24–04:02]; [03:51–04:02]
• The plan was for Banfield to stage a heroic intervention, shooting Ryan and blaming him for Christine's death, then faking evidence to support their narrative.
  • [05:42] B: “You would think, or they thought it was a good plan. Brendan Banfield comes in, saves the day, tries to save his wife, kills an intruder. That intruder, unfortunately, sadly, had already killed the wife. And that was supposed to be the story.”

3. The Au Pair’s Testimony – Strengths and Weaknesses

• Juliana Mahales' testimony is the crux of the prosecution’s case. She admitted to firing the fatal shot at Joe Ryan, but her credibility was heavily challenged.
• The co-hosts highlight that Mahales often couldn’t recall important details during cross-examination, such as who set up the FetLife account or who contacted potential co-conspirators.
  • [07:46] A: “She couldn't remember several key details when she went under cross examination...So if you want to be believed...to be missing major details like that is questionable.”
• The defense painted Mahales as lacking remorse and being self-serving, referencing letters she wrote that seemed to suggest ulterior motives—especially a Netflix deal she sought after being arrested.
  • [08:29] B/A:
    • B: “And then all of a sudden, she's talking about, I want to. I don't want to accept the Netflix deal. I want to negotiate. I can get other offers, other places. And her tone, her demeanor, everything about her changed.”
    • A (quoting a letter): “I'm going to sit down, talking with them, negotiating. I want a higher amount, especially since my whole life will be exposed to everyone, and they're going to be making a lot of money off it. We deserve something.”

4. Pivotal Moments in Courtroom Testimony

• The defense scored a dramatic moment by spotlighting Mahales’ use of “deserve” in her letters about profiting from her story.
  • [10:03] B: “He honed in on the word deserve. Because when you hear that, you, you all, we all kind of go, wait a minute, what? And he said it as plain like he was thrown off by her. What? He said, you shot a guy like…”
  • [10:32] A: "Girl, you deserve jail time."
  • [10:41] B: "That was a moment. That was a moment that the jury will remember."
• Commentary emphasized that this cast further doubt on Mahales’ motives and added weight to the defense’s effort to undermine her reliability as a witness.

5. Prosecution Rests – Blood Evidence & Last Witnesses

• The prosecution's case largely relied on Mahales, but they also promised forensic blood evidence linking Banfield directly to the killings.
• A bloodstain expert testified that blood patterns indicated the crime scene was staged, supporting Mahales’ version of events.
  • [11:57] A: “This bloodstained expert said that Joe Ryan's wounds flowed like the blood flowed in multiple directions, which would suggest he was moved after he was shot. And then she said that Christine's blood appears to have been intentionally spilled onto Ryan's hands and pants instead of naturally coming out of a wound.”
  • [12:44] A: “She actually made blood evidence interesting. The prosecution rested. The last of their 18 witnesses that they've called over these last nearly two weeks was Christine Banfield's father…He testified to Christine's medical condition that makes her bleed and bruise more easily.”
• The relevance of Christine’s father's testimony was questioned, with both hosts noting that it may not have resonated with the jury.

6. Defense Strategy and Early Moves

• The defense aims to dismantle the prosecution’s “catfishing” narrative and challenge the digital evidence.
• Crucially, a digital forensics expert testified there was no definitive proof that anyone other than Christine Banfield herself logged into or created the FetLife account, and his findings were peer-reviewed by a university team.
  • [14:31] B: “If they believe she did it, then the story's over, the trial is over, the outcome is assured."
• The defense attorney’s opening line set the stage:
  • [15:02] A (paraphrasing): “In the world of digital forensics, there is a saying, digital forensics doesn't lie. People lie.”
• The outcome now rests heavily on whether the jury believes the defense’s technical narrative over Mahales’ testimony.

Notable Quotes & Memorable Moments

• [01:14] A: “Prosecutors say that they conspired because they had started this affair. They wanted to live happily ever after together, but he needed to get rid of his wife...they came up with a plan of going onto a fetish website called FetLife.”
• [05:57] A: “That was the 911 call. That is what they actually said happened to authorities, but it was months later. They actually ended up arresting the au pair for her role.”
• [07:05] B: "It wasn't necessarily the story versus her demeanor, how she reacted, how she came off in a lot of what she's doing, being combative with the defense attorney...she didn't seem like she had remorse. She didn't seem like she took responsibility for her own role."
• [09:17] A/B:
  • A: “So the jury is looking at that and going to have to consider how much to. How much weight to give her testimony, when, I mean, it's clear she has a lot of incentive to say whatever they want her to say.”
• [10:41] B: “That was a moment that the jury will remember.”
• [11:57] A: “This bloodstain expert said that Joe Ryan's wounds...suggest he was moved after he was shot. And then...Christine's blood appears to have been intentionally spilled onto Ryan's hands and pants...”
• [14:31] B: “If they believe she did it, then the story's over, the trial is over, the outcome is assured. Because if the whole thing is that he set this up to kill her and you're telling me he didn't set up the account itself, then there is no rest of the story.”

Transcript

[A]

This is an I heart podcast. Guaranteed human. Hey there, everybody. Welcome to Amy and TJ Presents. We have been following one of the most salacious murder trials we have ever witnessed. It has been dubbed the Au Pair Affair Murders trial. It sounds catchy and maybe even a little cutesy, but there is nothing about this trial that is any of those things. This is as salacious as they get.

[B]

Yes. And so, folks, yes, we will focus on this. Amy and TJ presents with the Brendan Banfield trial out of Fairfax County, Virginia. Robes. This is one in which it sits exactly what it sounds like. There was an affair involving an au pair. It's almost a cliche at this point. Au pair comes from Brazil, ends up in an affair with the guy, and now two people are dead. One of those is the wife of Brendan Banfield. The other is an unsuspecting stranger who was lured to the house. That Brendan Banfield. According to authorities, Robes wanted to frame him for the murder of the wife. Now, that's the short and quick clean version. The details are what make this thing unbelievable.

[A]

Yes. According to prosecutors, Brendan Banfield, who, by the way, is a former former IRS agent, but they claim he, along with his au pair. Her name is Juliana Perez Mahales. She was only 20, 21 at the time. The prosecutors say that they conspired because they had started this affair. They wanted to live happily ever after together, but he needed to get rid of his wife. Prosecution said that for Brendan Banfield, divorce was not an option because of money and because of custody of his young daughter. And so according to them, they came up with a plan of going onto a fetish website called FetLife.

[B]

FetLife.com I finally remember it. That's why I jumped in.

[A]

You got excited.

[B]

Yes, I did.

[A]

Did you check it out like you said you were going to?

[B]

I'm nervous to. I don't want it on my.

[A]

I wouldn't want it on my computer either. Just one of those, like, let's not even go there. But I am a little curious. We've been talking about a lot about this website, but the plan was, according to prosecutors, that they posed as Brendan's wife, Christine, and said that she was looking for a violent sexual experience where she wanted a man to come to her home while she was pretend sleeping, come into the home with a knife, cut her clothes off, rape her at knife point, and no matter how much she said to stop or screamed, he. He should just keep going. And they found a taker.

[B]

So those are just deep. Look, people are into their thing. They do their thing and knock yourself out for them. I think it's fair to say, generally speaking, most people can't relate to something like this and wanting something like this. But, hey, this guy Joseph Ryan, Joe Ryan we've been hearing a lot about, had nothing to do with any of these people, wasn't connected to the family in any way. He answered an ad on a website and ends up dead. And a part of the scheme, as they say now ropes a big part of this, which is what's an interesting factor here, according to the au pair who has testified, is that it took them a little while to find a taker.

[A]

Yes. Because we are learning about how these fetish websites, or even just the fetish lifestyle works, but there is safety and trust involved. Obviously, if you're asking someone to violently do something to you to satisfy sexual needs, most people have understandings that they meet in person first, they establish trust, basically connect and say, even over coffee or a drink, yeah, here's what I want.

[B]

It sounds crazy, but it was explained to us by an attorney who has dealt with a bunch of these cases in her defense attorney career. She said there's a code to this, there are rules to this that people in that community respect.

[A]

Yes. So unfortunately for Joseph Ryan, according to prosecutors, he agreed to, to. To participate in this sexual fantasy without meeting in person. Because every other person, according to the au pair's testimony, who they tried to reach out to, they were basically going on email and trying to set up this scenario. And several people said, we, I'd like to meet in person first. And then they're like, on to the next, onto the next, onto the next, until they found Joe Ryan who said he would do this. And the plan was, according to, according to Juliana, that they found out or they knew when his wife Christine was off work. She's a ER nurse. I mean, she's an intensive care pediatric nurse. And so she obviously works crazy long hours. And so there are days where when she's off, she sleeps late into the morning, understand, she does overnight shifts. So they knew when she was going to be asleep. They left the door unlocked. They had this whole plan. The little girl, the four year old, was in the basement with an iPad. And the plan was that when Joe Ryan was doing what he thought he came here, that was mutually agreed upon to do. Brendan would walk in and shoot Joe Ryan and tell authorities he was stabbing my wife to death. I broke in and found this man attacking my wife and I shot him. And then he, according to the au pair, stabs his wife with the knife that Joe Ryan brought in his sexual fantasy, role playing and make it look like Joe Ryan actually killed his wife. And that was the plan?

[B]

Yeah, I mean, it's. You would think, or they thought it was a good plan. Brendan Banfield comes in, saves the day, tries to save his wife, kills an intruder. That intruder, unfortunately, sadly, had already killed the wife. And that was supposed to be the story.

[A]

And that was the 911 call. That is what they actually said happened to authorities, but it was months later. They actually ended up arresting the au pair for her role. And she. It took her almost a year, but she ended up finally admitting that she did fire the fatal shot, they believe, into Joe Ryan, and therefore she was charged with murder. And the defense's point is the prosecution flipped her to make up this story and to give her this story and feed this story to jurors to. To ultimately get the person they wanted, which was Brendan Bamfield. He's been charged with a double homicide and endangerment to his daughter because this all happened while she was in the home. So he is looking at life behind bars and he is now fighting for his life in this murder trial. But the au pair's testimony, and she took the stand last week is the foundation. And it might be if. If the jurors don't believe the au pair, the prosecution doesn't have a case. Her testimony is the key to prosecutors winning this case.

[B]

And let's be clear here, and we put ourselves as we watch these, in the position of the jurors as journalists, but also of the jurors and in this case sitting in there, it's hard to imagine how she came across that cross that. Well, to a lot of the jurors, it wasn't. It was more. It wasn't necessarily the story versus her demeanor, how she reacted, how she came off in a lot of what she doing, being combative with the defense attorney at times, you know, she didn't seem like she had remorse. She didn't seem like she took responsibility for her own role. In a way, it she, if they believe every word out of her mouth is still a tough messenger to get it from.

[A]

Absolutely. She couldn't remember several key details when she went under cross examination. She couldn't remember who set up the FetLife account, her or Brendan. She couldn't remember who emailed some of those potential sexual fantasy partners. So there were a lot of problems for her when it came to. To remembering key details. So if you want to be believed, and the jurors want to believe you know, what happened and what you're saying happened was true. To be missing major details like that is questionable. But perhaps one of her biggest problems was when the defense attorney had Juliana read letters that she wrote to Brendan and Brendan's mom when she was in prison for nearly a year. She was depressed, she was suicidal. She was professing her forever love to Brendan.

[B]

And.

[A]

And then we saw the letters that she wrote her family about a Netflix offer being offered $10,000.

[B]

Two different women in these letters.

[A]

Yes.

[B]

Once she got the deal, she became a different person based on those letters, in her own words. And again, she sounded like she was really spiraling downward for months and months and months to the point she was talking about taking her own life.

[A]

She was desperate.

[B]

And then all of a sudden, she's talking about, I want to. I don't want to accept the Netflix deal. I want to negotiate. I can get other offers, other places. And her tone, her demeanor, everything about her changed. And the argument from the defense is that, yeah, she got a sweet deal. This is it. Not true, Robes. It's the understanding that she fired the fatal blow into Joseph. Absolutely, Ryan. So the woman that did that is going to get to go home free.

[A]

Yeah.

[B]

So the jury is looking at that and going to have to consider how much to. How much weight to give her testimony, when, I mean, it's clear she has a lot of incentive to say whatever they want her to say.

[A]

Absolutely. I actually wrote the quote down when she talked or what. She had to read the letter she wrote her family about this Netflix deal. So she had to read this with jurors listening. I'm going to sit down, talking with them, negotiating. I want a higher amount, especially since my whole life will be exposed to everyone, and they're going to be making a lot of money off it. We deserve something. And the defense attorney really honed in on. You deserve something. Didn't you just admit to shooting and killing a man? But you deserve something. That was a. Maybe it wasn't a Perry Mason moment, but it was a big moment for the defense.

[B]

Well, there's. You're always watching. Try. And that's a lot of blood evidence. There's a lot of DNA stuff to go over. There's a lot of crime scene stuff, a lot of investigators up there, detectives and whatnot. Yeah. And so you're waiting on a moment that was one of the more dramatic ones. And it's not one that he had planned, because, of course, they have their list of questions, but he honed in on the word deserve. Because when you hear that, you, you all, we all kind of go, wait a minute, what? And he said it as plain like he was thrown off by her. What? He said, you shot a guy like.

[A]

Girl, you deserve jail time.

[B]

He said he absolutely incredulous. You shot somebody. Why do you deserve.

[A]

Yeah, you don't deserve thousands of dollars.

[B]

That was a moment. That was a moment that the jury will remember.

[A]

I agree. I agree. So when we come back, we're going to tell you how the prosecution rested their case this week and what the defense has in store for the jury. Welcome back everyone, to Amy and TJ presents where we are going over the very latest in the au pair affair murders trial. This week, the prosecution ran, rested its case. Of course, its case is almost entirely built around the au pairs testimony and whether or not the jury is going to believe her version of events. But they did promise some blood evidence that they said would connect Brendan Banfield to killing his wife. And we did hear from this bloodstain expert who said, and this does match the au pair's testimony, that after the killings, she says that Brendan adjusted the bodies to make it look like Joe Ryan stabbed his wife, Christine. And so this bloodstained expert said that Joe Ryan's wounds flowed like the blood flowed in multiple directions, which would suggest he was moved after he was shot. And then she said that Christine's blood appears to have been intentionally spilled onto Ryan's hands and pants instead of naturally coming out of a wound. She was describing how blood acts. You said you found that testimony fascinating.

[B]

Well, I. We watch a lot of true crime and how many times we hear that phrase blood spatter and it splattered and his blood spatter. Right. There's different words. So much of these crimes have to do with blood and how it behaves. She just, I thought was very good. Initially, I was sitting there as a student wanting to take notes as she explained how blood behaves. I found that very interesting. And she was better. We've heard a lot of blood experts. She spoke in a way that spoke to me.

[A]

We understood it, AKA we understood it. Which is not always the case when you're listening to people who are scientists. Like when you start having scientists describe DNA and exclusions, I start to glaze over. Exactly. So she actually made blood evidence interesting. The prosecution rested. The last of their 18 witnesses that they've called over these last nearly two weeks was Christine Banfield's father. I, I wasn't really sure why this was important.

[B]

What they got out of him.

[A]

But they, he testified to Christine's medical condition that makes her bleed and bruise more easily. So I, I don't know what the jurors got out of it. You hear Christine's father is testifying and it, I don't know, it didn't land maybe the way it wasn't up there very long either. He wasn't. He wasn't. And so, yes, the defense now begins its case. And look, their main goal was, and this mostly happened during cross examination, was to debunk this catfishing narrative that he was with the au pair in planning all of this. And her version events, they're trying to say is the prosecution's version events that they handed to her, she studied it and then she regurgitated it when she got up on the witness stand. But look, the other big thing they have is the digital forensics. And their is a member within the police department who has said he is a digital forensics expert, that the evidence does not prove that someone other than Christine the wife logged into that FetLife account. And he had his findings peer reviewed by a team at the University of Alabama who agreed with him that you cannot say that Christine herself didn't set up this FetLife account. And that is damning to the prosecution.

[B]

Oh, if they believe she did it, then the story's over, the trial is over, the outcome is assured. Because if the whole thing is that he set this up to kill her and you're telling me he didn't set up the account itself, then there is no rest of the story.

[A]

There's reasonable doubt as to what exactly happened in that bedroom and why it happened and how it happened. And this is about who you believe. But also, and this is, was. This was the opening statement of Brendan Banfield's defense attorney. He said, in the world of digital forensics, there is a saying, digital forensics doesn't lie. People lie. And there's going to be plenty to see. You're going to see manipulation within the police department. So that is going to be explosive testimony. And the defense is putting on a defense. And we will be watching. Want to let you all know too. We sat down with Alison Treason, criminal defense attorney Alison Treason. So if you've been a fan of this feed in this podcast, you will know that name because she has helped us and walked us through a couple of these trials we've been watching. She has some very, very interesting takes on what we've seen in this au pair affair murders trial. She's really into this one. So look for that. That episode will post shortly after this one, so please, please, please check that out. But in the meantime, thank you so much for listening to us. I'm Amy Robach alongside my partner, TJ Holmes. Talk to you soon. This is an iHeart podcast. Guaranteed Human.
