Nanny accomplice in suburban double murder seen in police footage after killings

A man named Joe Ryan was also killed as part of the alleged scheme after prosecutors say he was contacted on a sexual fetish website and lured to the Banfields' home with the promise of sex.

Banfield faces a potential life prison sentence for the alleged crimes, while Magalhães faces a maximum sentence of 10 years for the manslaughter charge, according to FOX 5.

When police responded to a 911 call from the Banfield residence Feb. 24, 2023, they found Christine with stab wounds to the neck and Ryan with fatal gunshot wounds in the upstairs bedroom of the home. Authorities took Christine to the hospital, where she was later pronounced dead.

Officials recovered a knife and two guns from the house.

It remains unclear exactly what transpired inside the home that Friday morning, but Magalhães and Brendan apparently both admitted to shooting Ryan while the man was holding a knife to Christine.

Viviane Magalhães, Juliana's stepmother, told The Associated Press she hopes her stepdaughter can return home to Brazil soon.

"We still can't figure this out. I believe she was fooled by this guy. He brainwashed her," Viviane Magalhães told the AP in Portuguese, referring to Banfield. "She was never a gold digger in Brazil. For many years, she dated a man who was as humble as she was. We could never think of her living a situation like this."

Banfield is no longer employed by the IRS.
