Summary
Brendan Miller, Detective with the Fairfax Co. Police Department, testified today in the Brendan Banfield murder trial. Banfield, a former IRS agent, is charged with four counts of aggravated murder in the February 2023 deaths of his wife Christine Banfield and Joseph Ryan at their Herndon, Virginia home.
Prosecutors allege Banfield plotted the killings with the family's Brazilian au pair, Juliana Peres Magalhães, with whom he was having an affair. Magalhães has pleaded guilty to manslaughter and is expected to testify against Banfield. The defense maintains digital evidence does not support the state's catfishing theory.
