IRS Agent Sentenced to Life for Double Murder Plot with Family's Au Pair

A Washington-area court has imposed a life sentence without possibility of parole on Brendan Banfield, an armed agent with the Internal Revenue Service, for carrying out a double killing that he planned together with his family's live-in nanny.

Banfield and his spouse Christine appeared to lead an unremarkable suburban existence in Herndon, Virginia, where they resided with their four-year-old daughter. That facade shattered in February 2023, when law enforcement responded to a call at their residence and discovered Christine dead from stab wounds and a second man, Joseph Ryan, shot to death in the master bedroom.

The emergency call came from Banfield himself and the family's Brazilian au pair, Juliana Peres Magalhães. Their initial account claimed they had walked in on Ryan assaulting Christine with a blade, prompting both Banfield and Magalhães to open fire on the intruder. The couple's young child was inside the house during the killings.

At first glance, the incident looked like a botched fetish encounter gone wrong. Investigators were told Christine had met Ryan through an adult dating platform and invited him to the home, where the liaison allegedly turned violent, with Banfield intervening to protect his wife.

However, detectives soon uncovered irregularities. Friends of Ryan maintained that while he enjoyed rougher intimate encounters, he always sought mutual consent. More troublingly, evidence began pointing to a relationship between Banfield and the au pair. After the deaths, he moved Magalhães into the house — the pair claimed they had only grown close following the traumatic events.

Further suspicious details emerged: Banfield and Magalhães had visited a shooting range together before the killings; he had replaced the bedroom windows with soundproofed versions; and the photograph allegedly used to create Christine's dating profile had been sent exclusively to Banfield, yet turned up in Magalhães's email correspondence.

Magalhães was arrested first and pleaded guilty to Ryan's slaying, receiving a ten-year term. She later negotiated a cooperation agreement, revealing that she and Banfield had meticulously planned Christine's murder step by step. Their scheme involved luring an unsuspecting man to the scene so the killing could be pinned on him, clearing the way for Banfield and Magalhães to be together.

Based on her testimony, authorities charged Banfield with two counts of homicide. The investigation confirmed Magalhães's version: Banfield stabbed his wife, they then shot Ryan, and staged the bedroom to resemble a violent sexual encounter that had spiraled out of control. Banfield maintained his innocence throughout but admitted to the affair with the nanny.

Judge Penney Azcarate handed down the final verdict this week, ordering Banfield to spend the remainder of his days behind bars with no prospect of release. In her remarks from the bench, she described the defendant's conduct as reflecting something far more profound than anger or impulse — "evil" — and stated she felt no hesitation in imposing the maximum punishment.
