Brendan Banfield found guilty of orchestrating double murder plot involving Brazilian au pair
A former IRS law enforcement officer has been found guilty of one of Virginia's most shocking crimes: a carefully orchestrated double murder plot designed to kill his wife and frame an innocent stranger.
Brendan Banfield, who spent years enforcing federal tax law as an IRS special agent, was convicted on Monday, February 3, 2026, of two counts of aggravated murder, one count of using a firearm during a felony, and one count of child endangerment. The verdict came nearly three years after the fatal incident on February 24, 2023.
Prosecutors presented evidence that Banfield's crimes were motivated by an extramarital affair with Juliana Magalhães, a Brazilian au pair employed by his family. The conspiracy allegedly centered on eliminating his wife, Christine Banfield, while simultaneously murdering Joseph Ryan, a stranger who Banfield apparently intended to use as a scapegoat to deflect suspicion from himself.

The case exposed a carefully laid plan that unraveled through investigation and testimony. The evidence presented to jurors detailed how Banfield leveraged his knowledge of law enforcement tactics—gained through his career with the IRS—to attempt what he believed would be an unsolvable crime.
Juliana Magalhães, the au pair at the center of the alleged affair, accepted responsibility for her role in the conspiracy. She pleaded guilty to manslaughter and is expected to receive time served as her sentence. Following her release, Magalhães is expected to be deported to her native Brazil.
The conviction carries severe consequences for Banfield. He is expected to spend the remainder of his life in prison, with no possibility of release. The sentence reflects the gravity of the two murders and the circumstances surrounding his calculated attempt to orchestrate them.
The case drew significant media attention, partly because of Banfield's position within federal law enforcement. An IRS special agent—someone trained to investigate financial crimes and entrusted with investigative authority—stood accused of committing murders that shocked the community and raised questions about how such a person could plan such violence.
Victims Christine Banfield and Joseph Ryan cannot speak to the impact of these crimes, but their deaths sent shockwaves through Virginia and beyond. The case also highlighted the vulnerability of the au pair system, where live-in employees can become entangled in family dynamics with potentially tragic consequences.
The conviction of Brendan Banfield marks the end of the trial phase in a case that captured national attention. It serves as a stark reminder that positions of trust and authority offer no immunity from criminal prosecution, and that meticulous planning does not guarantee success in evading justice.
