A Virginia man has been sentenced to life in prison without the possibility of parole after being convicted of orchestrating a double-murder plot involving the family's Brazilian au pair, a scheme prosecutors said was designed to eliminate his wife and clear the way for a future with his lover.
Brendan Banfield, a former Internal Revenue Service law enforcement officer, received the mandatory life sentence Friday in Fairfax County Circuit Court after being found guilty of aggravated murder in the deaths of his wife, Christine Banfield, and Joseph Ryan. The killings occurred on Feb. 24, 2023, at the family's home in Herndon, Virginia, according to court proceedings reported by The Associated Press.
Judge Penney Azcarate described Banfield's actions as calculated and cruel while handing down the sentence. In addition to life imprisonment, Banfield was sentenced to five years for child endangerment and three years on a firearms conviction. The child endangerment charge stemmed from the fact that the Banfields' 4-year-old daughter was inside the home during the killings, according to the news agency.
"The disregard of the life of your wife, someone you supposedly loved, is almost unfathomable," Azcarate said during the hearing. The judge also criticized Banfield for the impact of his actions on the couple's daughter, saying he had taken everything from her.
Prosecutors argued that Banfield carried out the plot with Juliana Peres Magalhães, a Brazilian au pair who began working for the family in 2021 and later entered into a relationship with him. During the trial, Magalhães testified that Banfield had spoken about marrying her and starting a family together but first needed to "get rid of" his wife. She told jurors that Banfield wanted to avoid divorce because of financial concerns and because he hoped to retain custody of his daughter, according to testimony cited by The Washington Post.
The case centered on an elaborate plan to lure Joseph Ryan, a man with no prior connection to the Banfield family, to the house under false pretenses. Prosecutors said Banfield and Magalhães created online messages while posing as Christine Banfield on a fetish website. The messages invited Ryan to the residence for what he believed was a consensual sexual encounter involving role-playing and a knife, according to evidence presented at trial and reported by NBC Washington.
Investigators said Magalhães waited outside the home with the couple's daughter while Ryan entered the house. She then contacted Banfield, who had been waiting nearby. Prosecutors told jurors that Banfield entered the residence and shot Ryan before stabbing Christine Banfield with the knife Ryan had brought to the meeting. Magalhães later testified that she fired an additional shot at Ryan after noticing he was still moving.
Banfield initially told police that he had arrived home to find Ryan attacking his wife and claimed he acted in self-defense. Prosecutors argued the scene had been deliberately staged to support that version of events. After hearing weeks of testimony, jurors rejected Banfield's account and convicted him of murder and related charges in February.
During Friday's sentencing hearing, Banfield continued to maintain his innocence. He argued that there had been disagreements among investigators regarding the prosecution's theory and suggested it would have been impossible for him to send some of the online messages used to lure Ryan to the home. Judge Azcarate rejected those arguments and cited Banfield's lack of remorse as one reason she had no hesitation in imposing the life sentence.
The hearing included emotional victim impact statements from relatives of both victims. Christine Banfield's sister, Danielle Hocker, described her sibling as kind, dependable and selfless, recalling a childhood spent together and the lasting void left by her death. Joseph Ryan's mother, Deidre Fisher, told the court that her son was known for helping others and frequently adopted elderly shelter dogs that many people overlooked, according to The AP report.
Ryan's aunt, Sangeeta Ryan, said Banfield had not only taken two lives but had also attempted to distort the truth about who the victims were. Family members from both sides urged the court to impose the maximum sentence available under Virginia law.
Magalhães pleaded guilty to manslaughter after agreeing to cooperate with prosecutors and testify against Banfield. Following his conviction, she was sentenced to 10 years in prison.
The case drew widespread attention because of the relationship between Banfield and the family's au pair, prompting some media outlets to label it the "au pair affair" case. Prosecutors maintained throughout the proceedings that Ryan was an innocent victim manipulated into becoming part of a murder plot whose true target was Christine Banfield.
