About The Au Pair Affair Murder Trial Of Brendan Banfield
A pediatric nurse stabbed to death. A stranger shot twice by two different guns. A 4-year-old waiting in the basement to go to the zoo. And a husband who says he's innocent.
The Au Pair Affair Murder Trial of Brendan Banfield is your complete source for daily coverage, analysis, and breakdown of one of the most anticipated murder trials of 2026.
On February 24, 2023, Christine Banfield and Joseph Ryan were found dead inside the Banfield home in Herndon, Virginia. Prosecutors allege Brendan Banfield — an IRS criminal investigator — and the family's Brazilian au pair, Juliana Peres Magalhaes, were having an affair and conspired to murder his wife. The alleged weapon? A fake profile on FetLife, a sexual fetish website, used to lure Ryan to the house as an unwitting patsy in a staged home invasion.
But this case is far from simple.
The prosecution's own digital forensics expert concluded Christine Banfield — not her husband — appeared to be controlling the FetLife account. His findings were peer-reviewed and confirmed. Then he was transferred out of the unit. The lead homicide detective who disagreed with command staff's theory was moved off the case. The lead prosecutor was removed after being cited for drinking at 8 a.m.
Now the state's entire case rests on Juliana Peres Magalhaes — who changed her story after a year in jail and took a plea deal that lets her walk free if she testifies against Banfield. She wrote to her mother from jail: "I'm heartbroken for doing this to Brendan... I want to be with you again."

Did Brendan Banfield orchestrate an elaborate murder plot with his young mistress? Or did investigators lock onto a theory before the evidence supported it — and punish anyone who disagreed?

Is There Any Way Brendan Banfield Gets Out of Prison?
It started with fake online profiles impersonating his wife and ended with a judge telling Brendan Banfield his crimes reflect evil. The au pair affair case is over. Banfield received life without the possibility of parole in Fairfax County court, plus consecutive sentences for child endangerment and a firearm charge. Every sentence runs back to back. He is never getting out.
The former IRS law enforcement officer was convicted of two counts of aggravated murder for the February 24, 2023, killings of his wife Christine and a stranger, Joseph Ryan, inside the family home in Herndon, Virginia. Banfield and the family’s Brazilian au pair, Juliana Peres Magalhães, devised the scheme so Banfield could avoid a divorce and custody fight. He catfished Ryan through a dating website, lured him to the house under false pretenses, shot him with his government-issued firearm, and stabbed Christine seven times in the neck. Their four-year-old daughter was in the basement. Magalhães eventually flipped, testified against him at trial, and was sentenced to ten years for her role.
At sentencing, Judge Penney Azcarate called the scheme unfathomable. Christine’s sister said Banfield’s actions were about power, not love. Ryan’s mother described her son as someone who fought for underdogs and lived a life of meaning. Banfield’s response was to proclaim his innocence, blame the system, and announce he loved Christine despite the affairs. His defense attorney has already declined to represent him on appeal. Azcarate appointed a new appellate lawyer. Banfield has thirty days to file, but the evidence against him was direct, the jury was decisive, and every legal argument his team raised has already been rejected.

Juliana Magalhães Sentenced: 10 Years In Banfield Case — "May It Weigh Heavily On Your Soul"
She told the truth. She still got the maximum.
Juliana Peres Magalhães stood before Judge Penney Azcarate on Friday expecting to walk out of the Fairfax County courthouse and begin deportation proceedings to Brazil. The prosecution had recommended time served — roughly two years — in exchange for her cooperation in convicting Brendan Banfield of aggravated murder.
Instead, she got ten years.
"You do not deserve anything other than incarceration and a life of reflection on what you have done," Azcarate told her. "May it weigh heavily on your soul."
The judge called this "the most serious manslaughter scenario this court has ever seen" and rejected any notion that Juliana was merely a young woman swept up in her employer's manipulation. She detailed the weeks Juliana spent messaging Joe Ryan, knowing she was bringing him to his death. The moment she hung up after Christine Banfield begged her to call 911. And the kill shot she fired into Ryan as he lay moaning on the floor.
"At any point for at least the month prior — or that day — you could have stopped this. The plan did not work without your full involvement."
The victim impact statements were devastating. Joe Ryan's mother, Deirdre Fisher, appeared via video from Florida, describing how she still hasn't taken down her Christmas tree since her son's murder. "I say good morning to him each day when I turn on the tree's lights," she said, "and I tell him I love him each night when I turn off the lights."
Juliana sobbed through her allocution, asking for forgiveness. The judge wasn't moved.
This is the final chapter for Juliana Peres Magalhães in an American courtroom. Brendan Banfield's sentencing comes May 8. The Au Pair Affair ends here.

Juliana Magalhães Sentenced: 10 Years — Judge Rejects Time Served Deal
She told the truth. She still got 10 years.
Juliana Peres Magalhães stood before Judge Penney Azcarate today expecting to walk out of the Fairfax County courthouse and begin the process of deportation to Brazil. That's what the prosecution recommended — time served, approximately two years, in exchange for her cooperation in convicting Brendan Banfield of aggravated murder.
Instead, she received a 10-year sentence.
Judge Azcarate's ruling defied expectations and rejected the plea agreement that brought Magalhães to the witness stand in the first place. Her testimony was devastating to Banfield's defense — she detailed how they created the fake fetish profile in Christine Banfield's name, how they lured Joseph Ryan to the house, how they moved the couple's 4-year-old child to the basement before entering the bedroom, and how she fired the shot that killed Ryan while Banfield stabbed his wife.
But cooperation isn't absolution.
The victim impact statements landed hard. Deirdre Fisher, Joe Ryan's mother, addressed the woman who pulled the trigger on her son. The Banfield family spoke to the complexity of Juliana's situation — acknowledging she was young, foreign, and manipulated — while making clear that none of that erases her choices.
Magalhães told the court: "I know my remorse cannot bring you peace. I pray for forgiveness, and I have never forgave myself."
This episode contains the full sentencing audio from today's hearing — the victim statements, Juliana's words to the court, and Judge Azcarate's decision. This is the final chapter for Juliana Peres Magalhães in an American courtroom. The Au Pair Affair ends here.
