Former Tax Investigator and Nanny Hatched Murder Plot Using Fake Online Identity
A federal agent and his household employee created a bogus dating profile to trick a man into their Virginia residence, then killed both the stranger and the agent's spouse while staging a break-in.
Former Tax Investigator and Nanny Hatched Murder Plot Using Fake Online Identity
A onetime IRS enforcement officer and the family's live-in caregiver crafted an internet deception to draw an unwitting visitor into their dwelling, then slaughtered both the guest and the officer's partner while fabricating a tale of a home invasion.
The scheme erupted into violence on February 24, 2023, inside a Fairfax County, Virginia property. Brendan Banfield, who had spent years probing financial crimes for the federal revenue service, placed an emergency call that afternoon. He informed the operator that an unknown assailant had breached his residence and attacked his wife, prompting him to open fire. Officers responding to the address found 39-year-old Joe Ryan lifeless from bullet wounds. Christine Banfield, a healthcare worker and mother, had been gravely wounded and succumbed after transport to a hospital.
For months, the household's Brazilian nanny, Juliana Peres Magalhaes, reinforced Banfield's account. Recordings from officer-worn cameras showed the young woman telling authorities she observed a knife-wielding stranger assault Christine before Banfield discharged his weapon. She described a chaotic scene of shouted commands and rapid movement.
Digital forensic work eventually shattered that narrative. Investigators traced communications on an adults-only social platform between Ryan and a user calling herself "Anastasia9." The exchanges, which appeared to come from Christine, proposed enacting an aggressive fantasy scenario inside the master bedroom. Ryan's relatives said he was drawn to imaginative intimacy but always insisted on mutual agreement; they rejected any suggestion he would force himself on anyone. Christine's circle similarly insisted the online persona bore no resemblance to the woman they knew.
Detectives also noticed photographs circulating on social networks depicting Banfield and Magalhaes in close physical proximity, including one shot of the pair sharing a bathtub. Following Christine's demise, the caregiver had shifted her belongings into the couple's sleeping quarters and hung her wardrobe where Christine's had been.
Prosecutors pieced together a theory: Banfield and Magalhaes had invented the "Anastasia9" character to hook Ryan. Once he arrived expecting a consensual encounter, the pair intended to murder Christine and cast Ryan as a violent intruder who died during a struggle. The trap would eliminate a wife Banfield no longer wanted and leave him free to continue his relationship with the nanny.
Magalhaes eventually reversed course. She entered a guilty plea to manslaughter carrying a ten-year prison term and became the prosecution's central witness. On the stand, she recalled questioning Banfield about simply divorcing Christine. She testified he rejected the idea because he refused to split custody of their child, remarking that things would be simpler "if she was not in the picture."
Banfield testified in his own defense, calling the accusation irrational and denying any scheme existed to remove his wife. The jury disagreed. They returned a guilty verdict, and the judge imposed a life sentence for the two killings.
At sentencing, Christine's sister delivered an emotional statement about the pain of losing a sibling after nearly four decades of love. Ryan's mother, Deirdre Fisher, also spoke, predicting Banfield would spend his remaining years contemplating his crimes and would be remembered only as a killer.
The case is examined in an A&E documentary series installment titled "Sex, Lies and Murder," as detailed by Law & Crime.
