Virginia Au Pair’s Jailhouse Letters Unveil Turmoil in Love Triangle Murder Trial

15 January 2026 U.S. News

HERNDON, Va. — In a gripping courtroom drama unfolding in Fairfax County Circuit Court, Juliana Peres Magalhães, the au pair at the center of a deadly love triangle, took the stand to read emotional jailhouse letters professing her love for Brendan Banfield. Banfield, a wealthy Virginia man, faces charges of aggravated murder in connection with the 2023 killings of his wife, Christine Banfield, and Joseph Ryan at their family home in the affluent suburb of Herndon.

Magalhães, who pleaded guilty to manslaughter in October 2024 for her role in the case, has become a pivotal witness in the trial. Her testimony on January 14 revealed the tangled web of emotions and loyalties that led to the fatal events. She explained that accepting the plea deal was the “right thing to do,” signaling a complex acknowledgment of her involvement.

During her second day on the stand, Magalhães read aloud a series of letters she wrote from jail, in which she expressed deep feelings for Banfield, painting a portrait of conflicted loyalties amid a volatile love triangle. The letters provide insight into the personal dynamics that prosecutors argue culminated in the brutal double homicide.

The trial has captivated the local community and drawn attention to the darker undercurrents that can exist behind the façade of an affluent suburban family. Brendan Banfield is accused of orchestrating the murders of his wife and Ryan, a close acquaintance, in a case that prosecutors describe as a tragic outcome of jealousy and betrayal.

Magalhães’s testimony is a key component of the prosecution’s case, as she not only reveals the emotional entanglements but also details her involvement in the events surrounding the killings. Her decision to plead guilty to manslaughter, a lesser charge, contrasts with Banfield’s aggravated murder charges, setting the stage for a dramatic courtroom confrontation.

The case has been closely followed by legal experts and the public alike, highlighting the challenges of navigating complicated relationships and the consequences of violent acts. The Fairfax County Circuit Court proceedings are expected to continue drawing significant attention as the prosecution and defense present their evidence.
