The quiet, tree-lined streets of Herndon, Virginia, are rarely associated with tales of “rape fantasy” plots, catfishing, and double homicide. However, as jury selection begins this week in January 2026, the trial of Brendan Banfield and the role of Juliana Peres Magalhães are set to expose a narrative so salacious and calculated it feels like the script of a dark psychological thriller.
At the heart of the case is a former IRS agent, his family’s Brazilian au pair, and a web of lies that resulted in the deaths of two people: Christine Banfield, a 37-year-old mother and nurse, and Joseph Ryan, a 39-year-old stranger who thought he was showing up for a consensual sexual encounter.
A “Heroic” Husband’s Story Unravels
On the morning of February 24, 2023, Brendan Banfield placed a frantic 911 call. He told dispatchers that an intruder had entered his home and stabbed his wife. He claimed that, in an act of desperate self-defense, he had shot the man to save her.
When Fairfax County police arrived, they found a gruesome scene in the master bedroom. Christine Banfield was clinging to life with multiple stab wounds; she later died at a hospital. Joseph Ryan lay dead on the floor from gunshot wounds.
Initially, the story seemed straightforward. But as investigators dug deeper, the “heroic husband” narrative began to rot. There was no sign of forced entry, and Ryan had no known connection to the Banfields. How did he get there, and why?
The Au Pair and the Bedside Photo
The first crack in the facade appeared during a search of the home. In the very bedroom where Christine had been killed, police found a framed photograph on the bedside table. It wasn’t a picture of Brendan and his wife; it was a photo of Brendan smiling alongside Juliana Peres Magalhães, the family’s 23-year-old au pair.
Detectives soon discovered that Banfield and Peres Magalhães had been embroiled in a passionate extramarital affair since late 2022. Prosecutors now allege that the duo didn’t just want to be together—they wanted Christine out of the picture without the mess of a divorce, and they were willing to orchestrate a double murder to achieve it.
The FetLife “Death Trap”
The most disturbing aspect of the prosecution’s case involves FetLife, a social networking site for the BDSM community. Prosecutors allege that Brendan Banfield created a fake profile to “catfish” Joseph Ryan.
Through these messages, Ryan was reportedly lured to the home under the impression that he was participating in a pre-arranged “rape fantasy” role-play with a willing woman. He was allegedly told that the woman would “resist” and that it was all part of the game.
According to court records, Banfield directed Juliana Peres Magalhães to call Ryan to confirm the details. While Ryan entered the home believing he was entering a consensual sexual encounter, Banfield was reportedly waiting at a nearby McDonald’s. Once Ryan was upstairs, Banfield returned, burst into the room with his service weapon, and shot Ryan in the head. In the ensuing chaos, prosecutors say Banfield stabbed his own wife, while the au pair fired the final, fatal shots into Ryan.
The Star Witness: A Plea for Justice
The tide turned significantly in late 2024 when Juliana Peres Magalhães pleaded guilty to involuntary manslaughter. As part of her plea deal, she has agreed to testify against Banfield.
She is expected to detail how Banfield “masterminded” the plot, taught her how to use a firearm at a local gun range, and coached her on what to say to 911 dispatchers. For the prosecution, her testimony is the “smoking gun” that links the affair to the cold-blooded execution of two people.
What’s at Stake
Brendan Banfield faces charges of aggravated murder, firearm offenses, and felony child abuse (as the couple’s 4-year-old daughter was in the house during the killings). If convicted, he faces life in prison. His defense is expected to paint the au pair as a manipulative liar who is pinning the blame on Banfield to secure her own freedom.
As the four-week trial commences, Northern Virginia waits to see if justice will finally be served for Christine Banfield and Joseph Ryan.
Protecting Your Home and Family: Insurance Tips for 2026
While this case is an extreme outlier, it serves as a sobering reminder of how quickly a home can become a center of legal and personal turmoil. Here are a few essential insurance tips to ensure your family is protected:
- Review Your Personal Liability Coverage: Most homeowners policies include liability insurance. In the event of an injury or death on your property, this covers legal fees and settlements. Ensure your limits are adequate for your total assets.
- Invest in an Umbrella Policy: For high-net-worth individuals or those with significant assets, an umbrella policy provides extra liability coverage (usually starting at $1 million) beyond your standard home and auto policies.
- Life Insurance and Estate Planning: Tragedies happen. Ensure your life insurance policy is up to date and that you have a clear will or trust in place to protect your children’s future.
- Understand “Crime Scene Clean-up” Coverage: Many people don’t realize that standard homeowners insurance often covers the professional cleaning required after a traumatic event in the home. Check your “additional coverages” section for peace of mind.
