'I Wanted Him to Let Her Go': Brendan Banfield Testifies Amid Competing Theories over Who Killed His Wife

In a tense Virginia courtroom, Brendan Banfield told jurors he was acting out of panic and fear, not premeditation, when he fired a gun on the day his wife was killed. The former IRS law enforcement officer testified that he did not stab his wife, Christine Banfield, but instead shot another man he believed was attacking her, insisting prosecutors have built the case on the wrong theory.

Banfield's testimony came as Fairfax County prosecutors continue to argue that he orchestrated his wife's death and attempted to frame the man who was also killed that day. The conflicting accounts place Banfield's credibility at the centre of one of the most closely watched murder trials in the region.

Banfield Describes a Scene of Panic and Bloodshed

Taking the stand, Banfield described returning home to what he said was a violent confrontation in his bedroom involving his wife, blood and a knife. As reported by AP News, he told the court he saw Joseph Ryan standing over Christine Banfield while holding a knife.

'I don't know that I've ever been more panicked in my life,' Banfield testified. 'I was hoping to de-escalate the situation. I did not want to shoot him. I wanted him to let her go.'

Banfield said he fired a single shot at Ryan in an effort to stop the attack. Moments later, he testified, the family's au pair also fired at Ryan.

Prosecution Alleges a Staged Killing

Prosecutors have laid out a sharply different version of events. They allege that Banfield fatally stabbed his wife himself and then lured Ryan to the home as part of a plan to frame him for the killing.

Central to the prosecution's case is evidence that Banfield and the au pair created a social media account in Christine Banfield's name on a platform catering to sexual fetishes. According to testimony, Ryan connected with that account and arranged to meet for a sexual encounter involving a knife on the day of the killings.

Affair and Au Pair's Role Under Scrutiny

The au pair, Juliana Peres Magalhães, has admitted to shooting Ryan and has pleaded guilty to manslaughter. Prosecutors have highlighted her romantic relationship with Banfield, which began months before Christine Banfield's death and continued afterwards.

In court, Chief Deputy Commonwealth's Attorney Jenna Sands presented letters and messages exchanged between Banfield and Magalhães, including discussions about love and future children. Cited by WIVB, Sands questioned Banfield about whether those feelings existed while his wife was alive and whether they provided a motive for murder.

'Definitely not,' Banfield replied, denying that the relationship motivated the killing. He acknowledged the affair but described it as volatile and said it did not begin in earnest until after his wife's death.

Defence Challenges Investigation and Witness Motives

Banfield's defence has sought to undermine both the prosecution's theory and the credibility of its witnesses. His attorney questioned Magalhães' motives, pointing to notes she wrote in jail about negotiating payments with true-crime authors and producers after her guilty plea.

The defence has also challenged the police investigation itself. A homicide detective testified that investigators were told early on that there were two possible theories in the case and that they needed to support the correct one. Defence lawyers argue this led police to focus too narrowly on Banfield as a suspect.

Digital Evidence and Timeline Disputes

A digital forensics examiner testified there was no indication that Christine Banfield lost control of her devices before the killings, a finding the defence says weakens the catfishing narrative.

Jurors were also shown video of Banfield being informed of his wife's death, in which he appears visibly distraught. However, prosecutors later questioned Banfield's account of leaving home early for an important work meeting on the morning of the killings. His supervisor testified that no such meeting was scheduled, adding another point of contention as the trial continues.
