On the morning of February 24th, 2023, police in Fairfax County, Virginia responded to a home in Herndon after receiving a call about a stabbing and a shooting. When officers arrived at the residence, they stumbled upon a horrific scene in the master bedroom. Joseph Ryan (pictured top right) was found deceased from multiple gunshots in the corner of the room. Christine Banfield (pictured top left) was in bed, suffering from multiple stab wounds.
Joseph was pronounced dead on the scene, while Christine was transferred to a nearby hospital. Unfortunately, she succumbed to her injuries shortly thereafter. Detectives were subsequently tasked with investigating what could have led to such a violent scene in this quiet Herndon neighborhood.
It was soon learned that the home where this event took place belonged to Christine Banfield and her husband, Brendan Banfield (pictured bottom left). The couple lived there with their daughter, who was four years old at the time, and their au pair, Juliana Peres Magalhães (pictured bottom right).
Per the initial narrative provided by Brendan and Juliana, the morning of February 24th was supposed to be a normal day. Juliana had plans to take the Banfield's daughter to the zoo in Washington, DC. Christine, who worked as a nurse, had the day off and planned to sleep in. Juliana told police that, shortly after leaving the house with the Banfield's daughter, she realized she forgot their lunches and turned around to go back and retrieve them.
Upon their return to the house, Juliana noticed a "strange vehicle" in the driveway. She called Brendan, who was picking up breakfast at a nearby McDonald's. Brendan raced home and instructed Juliana to bring his daughter into the home's basement. Juliana complied, then both she and Brendan ran upstairs into the master bedroom.
Both Brendan and Juliana said that they saw a man, later identified as Joseph Ryan, standing over Christine with a knife. Brendan reportedly drew a gun and ordered Joseph to drop the knife. According to Brendan and Juliana, Joseph did not comply and instead began stabbing Christine. Brendan then shot Joseph, causing him to collapse in the corner of the bedroom.
Brendan then said he began to provide aid to his wife while also calling 911. A short time later, Brendan noticed that Joseph was still alive. He said that he was afraid Joseph would get up and continue attacking, so he ordered Juliana to shoot Joseph again. Juliana followed Brendan's orders and delivered the final shots that ended Joseph's life.
The story that Brendan and Juliana told made it appear as if they were forced to act in self-defense after encountering a home intruder who had attacked Christine with a knife. However, as detectives continued to investigate, they learned that Brendan and Juliana were far from innocent victims who happened to stumble upon a violent scene.
