A Virginia jury has convicted Brendan Banfield, a 40-year-old former IRS law enforcement officer, on two counts of aggravated murder for the deaths of his wife, Christine Banfield, and Joseph Ryan in Herndon, Virginia, on February 24, 2023. Banfield was also found guilty of using a firearm during a felony and child endangerment. Sentencing is scheduled for May 8, with a mandatory life sentence without parole for the murder convictions.

Key Details from Testimony and Evidence
Banfield's Testimony
Banfield maintained his innocence throughout the trial. He acknowledged the affair with Magalhães but described it as casual and stated he had no intention of ending his marriage. He testified that both he and his wife had affairs during their nearly 20-year relationship but chose to remain together after couples therapy.
Banfield stated he returned home after receiving a call from Magalhães, entered the bedroom, and found Ryan attacking his wife. He testified that he announced himself as a police officer, saw Ryan make a "downward stabbing stroke," and then fired his gun. He stated he was attending to his wife when Magalhães retrieved a firearm from his safe and fired a second shot.
Magalhães' Testimony
Magalhães testified in accordance with the prosecution's theory. She stated that Banfield wanted to marry her, have children with her, and needed to "get rid of" his wife. She claimed Banfield did not want a divorce for financial reasons and to seek custody of their daughter.
According to Magalhães, she and Banfield impersonated Christine Banfield on FetLife.com to lure Ryan to the house. She testified that Banfield shot Ryan in the head, then stabbed his wife. She stated she then shot Ryan in the chest after seeing him still moving. Magalhães testified that Banfield staged the crime scene by applying his wife's blood to Ryan's body to make it appear as though Ryan had attacked Christine.
Prosecution's Case
Prosecutors presented evidence including blood patterns, statements from Banfield's testimony, and Magalhães' account. Lead prosecutor Jenna Sands alleged that Banfield and Magalhães created a plan involving BDSM role play, trips to a gun range, and false 911 calls. Sands stated that Banfield stabbed his wife multiple times before Magalhães contacted emergency services.
Prosecutors noted that DNA analysis of the knife used in Christine Banfield's stabbing found only DNA from Christine and Ryan, not Brendan Banfield.
Defense's Case
Defense attorney John Carroll argued that the investigation was flawed and that evidence was manipulated. He asserted that Magalhães maintained her innocence for a year before changing her account, suggesting her arrest was intended to secure her testimony against Banfield.
A digital forensics examiner testified that Christine Banfield maintained control of her devices prior to her death, which the defense argued did not support the prosecution's catfishing theory. During cross-examination, the expert conceded he could not identify a time when Banfield and Magalhães' devices were away from the home while accounts linked to the fetish website were active on Christine's devices.
The defense also presented evidence that Banfield's DNA was not found on the murder weapon and questioned the lack of corroborating evidence for the catfishing scheme. Banfield testified he did not know his wife's laptop password and never accessed her devices without her permission.
Additional Context

- Joseph Ryan's mother, Deidre Fisher, stated in court that her son's life was "used and thrown away."
- Prior to the trial, Magalhães had conversations with a media company regarding selling her story for a documentary, according to court filings.
