Brazilian au pair Juliana Peres Magalhães was sentenced to 10 years in prison with 2 years of probation for her role in a 2023 double murder plot in northern Virginia. Magalhães pleaded guilty to manslaughter for going along with former IRS agent Brendan Banfield in the killings of his wife Christine Banfield and Joseph Ryan, who was lured to the Banfield home under a false social media profile.

Why it matters

The case highlights the dangers of online deception and the tragic consequences that can result when individuals become consumed by an illicit affair. It also raises questions about the role of accomplices in violent crimes and how the justice system should weigh their culpability.

The details

According to prosecutors, Magalhães and Banfield created a fake social media profile posing as Christine Banfield to lure Ryan, a 39-year-old stranger, to the Banfield home. Once there, Ryan was stabbed to death. Magalhães and Banfield then each fired a shot, killing Ryan. Magalhães later turned on Banfield, testifying against him in exchange for a plea deal that reduced her charge to manslaughter.

  • On February 24, 2023, the murders of Christine Banfield and Joseph Ryan took place inside the Banfield home.
  • In October 2023, Magalhães was charged with the second-degree murder of Ryan.
  • In 2024, Magalhães pleaded guilty to manslaughter.
  • On February 13, 2026, Magalhães was sentenced to 10 years in prison with 2 years of probation.
  • Banfield's sentencing hearing is set for May 8, 2026.
