FAIRFAX COUNTY, Va. (7News) — The prosecution has called all of their witnesses in the Reston au pair double murder case, and now Brendan Banfield's lawyer will call his witnesses to try and offer alternate theories to everything the jury has heard so far as we enter the second week of the trial.

Banfield is accused of shooting and killing Joe Ryan, before stabbing his wife, Christine Banfield, to death. Prosecutors said Banfield was having an affair with the family's au pair, Juliana Peres Magalhaes, and he orchestrated the complex double murder scheme so he could run off with her. The plan allegedly revolved around creating a fake profile on a fetish website so they could lure a man and make it look like Brendan Banfield tried stopping a home invasion-in-progress.

On Tuesday, prosecutors called their final two witnesses.

The majority of the day was spent on listening to testimony from a blood stain pattern expert.

For the first time in the trial, prosecutors showed people in the public seating area crime scene pictures with Joe Ryan still there. Until that point, they only showed the public seating area pictures of the scene after Ryan's body had been removed. One woman sitting in the victims' family seating area dropped her head and closed her eyes to avoid seeing these images.

Over the course of several hours, Iris Dalley Graff walked the jury through the gruesome crime scene pictures showing the blood-soaked scene.

Specifically, she testified the blood from some of Joe Ryan's wounds flowed in multiple different directions, suggesting he was moved after being shot.

Dalley Graff also said Christine's blood appears to have been intentionally spilled onto Ryan's hands and pants, instead of naturally pouring out of a wound.

"There are several blood stains on the right leg. In particular, there’s a stain parallel of somewhat parallel transfers that are finger-like in shape," Dalley Graff said. "Some surface wet with blood was in contact with the hand, so that blood transferred from the wet, bloody surface to the hand."

This testimony seems to support earlier testimony by Peres Magalhaes.

The au pair said Brendan Banfield moved Joe Ryan's body to get Christine Banfield's blood on him after killing them both, to make it look like Mr. Ryan murdered Mrs. Banfield.

During the last few minutes of the day, the prosecution then called Gary Benson to the stand.

Benson is Christine Banfield's father, and he testified his daughter dealt with a medical condition that made her bleed and bruise more easily all her life.

The trial continues Wednesday at 10 a.m., with Brendan Banfield's lawyer expected to call his first witness.

TUESDAY'S TESTIMONY

Just before 10:20 a.m., Iris Dalley Graff of Graff Investigative and Forensic Training was called to the stand as an expert in bloodstain pattern analysis. Banfield's defense raised multiple objections during the testimony of a key witness. The defense argued that the prosecution's line of questioning was leading, potentially influencing the witness's responses.

Dalley Graff was tasked with analyzing crime scene photos from the Banfields’ main bedroom, focusing specifically on the flow of blood. Technical difficulty with the court's computers and printer prompted a 15-minute recess around 11:00 a.m.

When the court came back in session, Dalley Graff started analysing photos of Joseph Ryan's body, the stranger that Banfield alleged lured to his home with a fake dating profile under his wife's name.

Dalley Graff pointed out a blood stain on Ryan's hand, which she explained was transferred from "some object wet with blood." Last week, the prosecution laid out a theory in which Ryan's body was transferred. Dalley Graff's testimony was interrupted a number of times due to the defense's objections of relevancy and leading the witness.

The court was on recess until 1:45 p.m., after which the defense began to cross-examine Dalley Graff.

Court is in recess until 3:30 p.m.

Christine Banfield's father, Gary Benson, takes the stand at 3:30 p.m.

Banfield described Christine dealt with frequent nosebleeds in her childhood but it was unclear what the medical diagnosis was. The defense team asked Benson about Christine wearing helmets in outdoor activities and playing sports in childhood and into adulthood.

The state rests for the afternoon. Jury was released at 3:45 p.m.

TRIAL RECAP

The first week of the trial for Brendan Banfield went by quickly, with prosecutors going through five witnesses on the first day before putting his alleged affair partner and accomplice, Juliana Peres Magalhaes, on the stand.

Peres Magalhaes, the Banfield's au pair, painted a picture across two days about her alleged affair with Banfield, and what he told her before they allegedly killed Brendan's wife, Christine, and another man they lured to the house with a fake online dating profile.

She also meticulously went through the steps they allegedly took leading up to the killings.

The trial is expected to last up to four weeks, though the judge has remarked it has moved more quickly than anticipated.

The alleged partner takes the stand

Juliana Peres Magalhaes, the family's au pair with whom Banfield was having an affair at the time of the alleged double murder, has admitted to her role in the killings and is cooperating with authorities as part of a plea agreement.

She claimed Banfield told her of his plans to kill Christine, got her to learn how to shoot a gun, and told her where to park on the day of the planned killings.

During her testimony, she said Brendan Banfield created the FetLife profile on Christine Banfield's computer, and he only used it when she was home because he was anticipating detectives investigating her death would be able to see where her cell phone was pinging. She also said they stopped communicating with other users on the website who wanted to meet in person before coming to the house.

Eventually, Peres Magalhaes said Brendan Banfield settled on Joe Ryan because he agreed to come to the house with a knife and ropes, thinking he was taking part in consensual sexual roleplay.

Banfield's defense argued Peres Magalhaes is an unreliable witness because she could not remember certain details and dates, though he admitted to the affair.

The credibility challenge came to a crescendo when Banfield's lawyer had the former au pair read letters she wrote in jail.

Many of those letter point to her emotional state and desperation in the days and months leading up to her agreeing to a plea deal, which requires her to testify against Mr. Banfield in exchange for a lesser charge.

However, attention quickly turned to one letter she wrote to her family, in which she claimed Netflix offered her $10,000 for exclusive rights to her story, but she wants to negotiate for more money.

"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 of it. We deserve something," Peres Magalhaes said.

Banfield's lawyer asked her why she deserved something after shooting and killing someone, and she clarified she meant her family needs money for what she had put them through.

Detectives and other county officials on the stand

Officers who responded to the scene took the witness stand early on, alongside a Fairfax County 9-1-1 official and the county's medical examiner, in order to outline what police came across at the Banfield home on the 13200 block of Stable Brook Way in February of 2023.

After Peres Magalhaes spoke, more detectives provided a look into the home immediately after the murders and in the months since.

Fairfax County Police Officer Kenner Fortner took pictures of the vehicles at the home the day of the alleged double murder, the drawer of the bar cart in the kitchen where Christine Banfield's phone was located, as well as portions of the bedroom away from the blood-stained scene.

On the day of the alleged murders, Fortner took photographs of the guest bedroom where Peres Magalhaes was living. The closet was full of her clothes, including lingerie.

Fortner returned to the Banfield home eight months later to execute a warrant. He took pictures of the primary bedroom where Brendan Banfield slept, where you could see Peres Magalhaes' clothes in the shared closet.

Additionally, pictures of Brendan and Christine Banfield were replaced by pictures of Brendan Banfield and Peres Magalhaes, on the bedside table next to the area where Christine Banfield was murdered less than a year earlier.

Detective Terry Leach, the lead crime scene detective, showed crime scene photos so gruesome that they were not shown to the courtroom as a whole. People sitting in the public seating area of the court were able to see some of the crime scene photographs showing blood stains on the carpet and clothes, as well as the gun and knife used.

Leach then showed surveillance video that provided insight into the timeline of events before the alleged double murder.

During her testimony, Peres Magalhaes said Brendan Banfield planned to wait at a nearby McDonald's until she called him to say Ryan had arrived at the house.

The surveillance video at the fast food restaurant showed Banfield ordering food through the drive-thru, then parking his car.

He then could be seen on camera walking inside and entering the bathroom.

About eight minutes later, at 7:37 a.m., he could be seen leaving the bathroom with his phone to his ear, walking to his car, and driving away.

Leach then showed call logs for both Banfield's and Peres Magalhaes' phones, showing the au pair called him at the time he was walking out of the McDonald's bathroom.

Peres Magalhaes also testified on Tuesday that the plan was for both of them to also call Christine Banfield, to make it look like they were trying to alert her, even though her phone was turned off and hidden in the kitchen while she was asleep in the bedroom.

The call logs also confirmed that Brendan Banfield and Peres Magalhaes made outgoing calls to Christine.
