Prosecutors say Brendan Banfield concocted an elaborate scheme to kill his wife, Christine Banfield, and another man, Joseph Ryan, in their family home in February 2023. When the incident first unfolded February 24, 2023, the au pair, Juliana Peres Magalhães, and Banfield called 911 to report the incident from the scene. They told investigators Peres Magalhães saw Ryan enter the house early that morning and called Brendan Banfield, who rushed home to investigate. Banfield’s defense attorney has accused prosecutors of offering Peres Magalhães a way out of prison in exchange for a false story to pin the murders on Banfield. The defense called a digital forensics expert witness who told the jury that, based on his analysis, digital data from devices belonging to Christine Banfield, Brendan Banfield and Peres Magalhães does not support prosecutors’ catfishing theory.
