Au Pair Affair Turns Deadly: Brendan Banfield Allegedly Plotted Wife's Murder Using Fetish Website

She moved to America for a fresh start. She ended up helping cover up a double murder — according to prosecutors.
Juliana Peres Magalhães was a 22-year-old Brazilian au pair living with the Banfield family in Herndon, Virginia. She cared for their four-year-old daughter. She became part of their home. And prosecutors say she became romantically involved with Brendan Banfield — a federal IRS agent — months before his wife Christine was stabbed to death in their master bedroom.
On February 24, 2023, Christine Banfield and a man named Joseph Ryan were both killed inside the Banfield home. Brendan and Juliana initially told police Ryan was an intruder who attacked Christine with a knife. They claimed they shot him in self-defense.
But prosecutors allege the entire thing was staged. They say Brendan created a fake profile on FetLife — a fetish dating site — using Christine's photo to lure Ryan to the house. Ryan thought he was meeting a woman for consensual role-play. Instead, according to prosecutors, he was set up to take the fall for a murder Brendan allegedly committed himself.
Juliana has since pleaded guilty to manslaughter and is cooperating with prosecutors. She says Brendan gave her a gun that morning and told her to shoot Ryan if he was still moving. The defense says her testimony is unreliable — the word of a woman trying to avoid prison.
Brendan Banfield's trial is set for January 2026. He faces life in prison. The only witness talking is the one who already cut a deal.
