Jurors in Fairfax, Virginia have begun deliberations in the trial of Brendan Banfield, a former IRS law enforcement officer accused of conspiring with the family's Brazilian au pair, Juliana Magalhães, to kill his wife Christine and frame a stranger, Joe Ryan, for the murder.
Why it matters
This high-profile case has captivated the community, raising questions about the breakdown of trust within families, the abuse of power, and the lengths some will go to cover up their crimes. The outcome will have significant implications for those involved and could set precedents around domestic violence, infidelity, and the credibility of witness testimony.
The details
Prosecutors allege that Banfield and Magalhães, with whom he was having an affair, plotted for months to get rid of his wife. They claim the pair created a fake social media account in Christine Banfield's name on a fetish platform to lure Ryan to their home, where he was shot and stabbed in an attempt to make it look like he had attacked Christine. Banfield denies the plot, testifying that he shot Ryan to stop him from killing his wife, and claiming he and Christine each had affairs during their marriage.
- Jurors began deliberating on Friday, January 30, 2026.
- The alleged murders took place on February 24, 2023.
- Magalhães pleaded guilty to a lesser charge of manslaughter in 2024.
