Brendan Banfield Faces Sentencing in Fairfax County Friday
Brendan Banfield is set to be formally sentenced on Friday, June 5, in Fairfax County after his convictions in the deaths of Christine Banfield and Joseph Ryan. A judge denied a motion on Thursday to dismiss his conviction, and Banfield will face a mandatory life sentence.
Fairfax County Court
The sentencing follows a case that began in August 2022 and moved through a February 2023 investigation. Banfield was convicted in the deaths of his wife and Joseph Ryan, and the court date now puts the penalty phase in front of the same county court that handled the case.
For Christine Banfield’s family, the hearing is the point at which the verdict turns into sentence. For Banfield, it means the court is set to impose the life term tied to the convictions already returned against him.
August 2022 Affair
Court filings show Banfield began an affair with the family’s au pair, Juliana Peres Magalhaes, in August 2022. In the fall of 2022, filings say he expressed a desire to be “rid of” Christine Banfield, then made a fake account on a fetish website and began communicating with Ryan.
Banfield posed as his wife on that site to lure Ryan to the home, then told Peres Magalhaes to use Telegram just days before the murders to confirm consent and meetup details. By January 2023, he had purchased a gun and given it to her, and prosecutors said he trained her at a gun range in the months before the killings.
Reston Home On Feb. 24
The killings took place on Feb. 24, 2023, at the Banfield home in Reston, in the 13200 block of Stable Brook Way. Banfield convinced Ryan that he was meeting Christine Banfield for a consensual sexual encounter, turned off his wife’s phone and left it in a kitchen drawer, and waited at a nearby McDonald’s so he could return quickly.
When Ryan entered the home, Peres Magalhaes made calls to both Christine and Brendan Banfield’s phones. Banfield later returned with Peres Magalhaes and his then 4-year-old daughter, left the child downstairs, went upstairs, announced himself as a police officer, and shot Ryan in the head with his service-issued firearm. Peres Magalhaes then made a brief 911 call and ended it at Banfield’s direction before Banfield stabbed his wife to death. When Ryan showed signs of movement, Peres Magalhaes shot him again.
Peres Magalhaes Arrested
Police arrested Peres Magalhaes in October 2023. During police interviews, she admitted to shooting Ryan, and later gave a detailed account that investigators said was corroborated by physical and digital evidence.
That evidence now sits behind Friday’s sentencing, after a denied bid to throw out the conviction. The court has already cleared the challenge, and the remaining step is the punishment the judge will impose under the mandatory life sentence.
