Virginia Man Faces Trial for Alleged Double Homicide Involving Wife and Au Pair

Brendan Banfield, a former IRS agent, is scheduled to stand trial starting January 13, 2026, in Fairfax County Circuit Court, facing charges related to the deaths of his wife, Christine Banfield, and Joseph Ryan. The trial, presided over by Chief Judge Penney S. Azcarate, is expected to last approximately four weeks.

Prosecutors allege that Banfield conspired with the family's au pair, Juliana Peres Magalhães, to orchestrate the killings. The plan reportedly involved luring Ryan to the Banfield residence under false pretenses to frame him for Christine's death, while making Ryan's own death appear as self-defense. Peres Magalhães, who was initially charged with murder, pleaded guilty to involuntary manslaughter in October 2024 and has agreed to cooperate with the prosecution.

The case has experienced multiple delays, with the trial date being postponed from October 2025 to January 2026 to allow the defense more time to review evidence. In December 2024, Banfield was additionally indicted on charges of felony child abuse and neglect, as his then 4-year-old daughter was present in the home during the incident.

In July 2025, Judge Azcarate ruled that a recorded interview with Banfield's daughter could not be used as evidence in the trial, citing legal statutes regarding the admissibility of such interviews. The trial is set to commence with jury selection on January 13, 2026, and will be open to media coverage, including still photos and video recordings.
