Ex-IRS Agent Convicted of Murdering Wife and Stranger

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.
