Banfield’s account in Fairfax County courtroom
Brendan Banfield, a defendant in an aggravated murder trial in northern Virginia, testified Thursday that prosecutors misstated how his wife, Christine Banfield, died in 2023. In his account to the jury, he said he did not fatally stab his wife, and that instead he shot Joseph Ryan, who Banfield said was holding a knife while standing over Christine Banfield.
Banfield described fear he said he felt when he saw the knife and blood in the bedroom. “I don’t know that I’ve ever been more panicked in my life,” he testified. He told the court that he hoped to de-escalate, and that he did not want to shoot Ryan, saying he wanted Ryan to let Christine Banfield go.
Banfield said he fired a single shot at Ryan, and he also testified that Banfield’s romantic partner and the family’s au pair, Juliana Peres Magalhães, shot Ryan moments later.
Prosecutors’ theory and Magalhães’ testimony
Banfield’s statements came as Fairfax County prosecutors have advanced a different theory of the killings. Prosecutors have said Banfield stabbed his wife and lured Ryan to the house as a way to frame him. Magalhães, who has testified in the case, said she and Banfield created an account in Christine Banfield’s name on a social media platform for people interested in sexual fetishes.
The AP report said that Ryan then connected with that account and planned to meet for a sexual encounter involving a knife on the day of the killings.
Cross-examination centers on the relationship
Banfield’s attorney, John Carroll, focused on Magalhães’ motives, and the AP report said Carroll scrutinized notes and communications connected to her testimony. The prosecutor, Chief Deputy Commonwealth’s Attorney Jenna Sands, also questioned Banfield’s statements about his feelings and his relationship with Magalhães.
Sands presented letters and messages Banfield sent to Magalhães before and after the killings, which included discussion of baby names and messages about love. In court, Sands asked whether the “very strong feelings” Banfield described about a life together existed when his wife was alive, and whether those feelings motivated him to kill Christine Banfield.
Banfield said in response that he and Magalhães “weren’t even together when Christine died,” acknowledging what the report described as a volatile affair. Sands later asked whether Banfield needed to kill his wife to get her back, and Banfield replied, “Definitely not.”
Defense challenges the investigation’s “two theories”
Banfield’s testimony followed defense efforts to challenge how investigators handled the case. The AP report said Banfield’s attorney argued the county forced a theory early and ignored evidence that undermined it.
During testimony described as part of the defense case, homicide detective Leah Smith said the defense presented evidence about the investigation, including testimony that officials told investigators there were two theories and that they needed to get behind the right one. The AP report said Smith testified that a supervisor told her and other investigators that early in the incident there were two theories and that the team needed to follow the correct one.
Defense witnesses and evidence also included testimony from Brendan Miller, described as a digital forensics examiner at the department. Miller concluded, the AP report said, that there was no indication that Christine Banfield lost control of her devices before the slayings.
Video and the morning timeline Banfield described
The AP report said jurors watched a video showing Banfield learning of his wife’s death. After the video was shown, Banfield took the stand and described in detail what he said he had done earlier that morning.
Banfield testified that he woke up, took a shower, and said goodbye to Christine Banfield before leaving his home extra early for what he said was an important work meeting with other agents and his manager. He told the jury the meeting was important to his work, the AP report said, because he had been told success in the case could lead to promotion to a senior special agent.
Testimony after that, the AP report said, included his boss testifying that there was no such meeting on the calendar.
