A Virginia jury has convicted former IRS law enforcement officer Brendan Banfield of aggravated murder for the 2023 deaths of his wife, Christina Banfield, and another man, Joseph Ryan.
Banfield, aged 40, was found guilty in Fairfax County for fatally shooting his 37-year-old wife and 38-year-old Ryan. Prosecutors argued that he deceitfully lured them to a home in Herndon, claiming it was safe. The jury spent much of Monday deliberating before reaching a verdict on January 30.
In addition to the murder charges, Banfield was also found guilty of using a firearm during the crime and for endangering his then-4-year-old daughter by leaving her in the basement while the violence transpired upstairs.
The jury took about nine hours to come to its decision, which included seven women and five men. Testimony presented by prosecutors indicated that Banfield had plotted the murders with Juliana Perez Magalhães, a 25-year-old Brazilian au pair with whom he had an affair.
It was revealed that the two had created a fake online profile, pretending to be Christina, to trick Ryan into coming over for what was purported to be a consensual encounter that had a darker intention. Ryan arrived, armed with a knife, unaware of the trap that had been set for him. He engaged with Christina, who worked as a pediatric ICU nurse, and had a background in dealing with sensitive cases.
Magalhães testified that she was waiting outside and contacted Banfield to falsely report an intruder, urging him to return home. Once inside, Banfield shot Ryan, claiming it was to protect his wife, and then stabbed Christina multiple times to stage the scene and frame Ryan for murder, according to prosecutors. Magalhães said she witnessed the stabbing and later assisted in calling for help.
While testifying, Banfield admitted to shooting Ryan but insisted that he acted in self-defense, stating that he believed Ryan was attacking Christina. His attorney argued that Magalhães had concocted the entire story to save herself and pointed out that a plea deal she had accepted led to her own sentencing.
Prosecutors maintained that various forms of evidence, including digital data and forensic analysis, indicated Banfield’s motive for wanting to remain with the au pair, rather than divorce his wife. “He was in love with Juliana,” prosecutor Jenna Sands noted to the jury, suggesting that Banfield had to eliminate his wife to be with her.
In her closing statements, Sands argued that the jury had a wealth of evidence to consider, beyond just Magalhães’ testimony. This included expert analyses showing that blood on Ryan’s hands seemed to have dripped from an elevated position, implying the scene was staged.
Banfield now faces a potential life sentence without the possibility of parole. His sentencing is set for May 8.
Magalhães will be sentenced following Banfield’s trial.
