Virginia prosecutors are pointing to blood-splatter analysis as one key piece of evidence that led to the arrest of a former IRS employee in connection with the 2023 murders of his wife and an unknown man in the idyllic Washington, D.C., suburb of Herndon, according to local reports.
Brendan Banfield, a husband and the father of a then-4-year-old daughter, and his family’s then-22-year-old Brazilian au pair, Juliana Peres Magalhaes, are accused of killing Christine Banfield — Brendan’s wife and Fairfax County NICU employee — and Joseph Ryan, the 38-year-old man who showed up at the Banfields’ home armed with a knife, in Herndon, Virginia, in February 2023.
Ryan’s connection to the family or their au pair remains unclear.
Fairfax Commonwealth’s Deputy Attorney Eric Clingan told a courtroom on Sept. 27 that after investigators spent a year of reviewing “two definitive reports from expert forensic investigators,” prosecutors determined they had enough evidence to prove their theory that Ryan and Christine’s bodies were moved after death. Ryan’s arms were moved and had Christine’s blood on them, according to the Associated Press.

“On Feb. 24, 2023, I stood in the middle of a cul-de-sac street in Fairfax County and described the deaths of two persons inside of a residential home. Now, 570 days later, we know the deaths of Joseph Ryan and Christine Banfield are, in fact, murders,” Fairfax County Police Department Chief Kevin Davis said during a September press conference.

Christine Banfield was stabbed to death in the bedroom of her Fairfax County, Va., home.
When police initially responded to a 911 call from the residence that day, 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, Davis said.
Officials recovered a knife and two firearms from the scene.

“We know Brendan Banfield and Juliana Magalhaes were involved in a romantic relationship at the time of the murders,” Davis said during the September press conference. “I will not describe our victim, Joseph Ryan’s, involvement with anyone in the case at the moment because this investigation continues,” Davis said.
Fairfax County police initially responded to the double homicide in the 13200 block of Stable Brook Way in Herndon, Va., on Feb. 24, 2023.
On Feb. 24, 2023, Magalhaes told police she left the Banfields’ home in the 13200 block of Stable Brook Way in Herndon to take their young daughter to the National Zoo. She told authorities that she had begun driving but realized she had forgotten the lunches she packed for their excursion inside the house, so she turned around and noticed an unfamiliar car in the driveway.

She then reportedly called Brendan, a former criminal investigative agent for the IRS who had at that point left for work, and told him about the unknown car in their driveway. The pair decided to meet at the Banfields’ home and walk inside together, as the Washington Post reported.
Initially, Magalhaes told police that when she and Brendan walked inside, they saw an unknown man, Ryan, holding Christine at knifepoint. She allegedly described him as an intruder. Ryan was apparently fully clothed while Christine was naked in the main bedroom of the house.

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

Prosecutors allege that a computer at the Banfield home was tied to an account on a sexual fetish website, the Post reported.

While the account on that computer appeared to show a photo of Christine in a bathing suit, it is unclear exactly who was communicating on the account. The profile also apparently did not display “one iota of evidence that she was into knife play, binding, BDSM,” Clingan previously said in court, according to the Post.
Ryan, the man who reportedly held Christine at knifepoint, also apparently had an account on the website and had been communicating with whoever was accessing the site from the Banfield computer.
A framed photo of Brendan Banfield and Juliana Magalhaes, as well as lingerie, were found in the room where the double homicide occurred, according to prosecutors.
Authorities arrested Magalhaes in October 2023 after she moved in to the Banfields’ main bedroom and placed a framed photo of herself with Brendan on a nightstand beside the bed. A grand jury indicted the 23-year-old in April, and her trial is scheduled to take place in November.
Magalhaes’ attorney, Ryan Campbell, did not respond to an inquiry from Fox News Digital. Brendan is no longer employed by the IRS, the agency confirmed.

A fatal collision between a motorcycle and a pickup truck on Thursday evening has claimed a life and prompted a significant road closure in South Reno.
The Nevada Highway Patrol (NHP) responded to reports of the crash at approximately 5:29 p.m. on February 26. The incident occurred on northbound South Virginia Street, just north of Damonte Ranch Parkway.
According to the Nevada State Police, the rider of the motorcycle, an adult male, was pronounced dead at the scene by emergency medical personnel. The driver of the pickup truck remained on-site, though no further details regarding other injuries or the cause of the crash have been released. Northbound South Virginia Street: Completely shut down from Damonte Ranch Parkway to Bishop Manogue Drive.
Southbound South Virginia Street: Open, but expect “rubbernecking” delays as drivers pass the emergency vehicles. Officials expect the northbound lanes to remain closed until at least 11:30 p.m. as the NHP Highway Patrol Division completes their investigation.

HAMPTON ROADS— A proposed initiative known as The Guardian Network seeks to strengthen coordination and public access to verified information when children, seniors, and vulnerable adults go missing in Virginia.
The effort is being led by Commonwealth Attorney Krystyn Reid, with support from Sen. Danny Diggs through a budget amendment to SB30. If the amendment passes, development would move forward through the Virginia State Police.
Reid said the idea grew from her years of public service.
“The difference between politics and public service is simple,” Reid said. “One is what you say. The other is what you do.”

Reid began her career representing domestic violence survivors and said she witnessed firsthand how quickly families can be thrown into crisis.
“When someone does not make it home, that is a family’s worst moment,” Reid said. “The Guardian Network comes from a belief that we can strengthen coordination in those first critical hours and better protect vulnerable communities.”
The network is designed to complement existing alert systems such as AMBER, Silver, Ashanti and CODI alerts. Participation would be voluntary for both families and the public.
“It does not replace them. It reinforces them,” Reid said. “What we lack is one centralized, accessible place to see verified information. This is about coordination and clarity.”
Currently, information can be fragmented, she said, making it harder for families and communities to respond effectively.

“Families in crisis should not have to search multiple platforms,” Reid said. “Public safety requires structure. Our response should be organized and accessible.”
The United Way of the Virginia Peninsula has expressed support for the initiative, citing its alignment with the organization’s mission to improve lives by advancing education, financial stability and health.
“Children are the highest age demographic experiencing eviction and homelessness, which creates unique vulnerabilities including separation, exploitation and trafficking,” said Charvalla West of United Way of the Virginia Peninsula. “Seniors face increasing isolation, housing instability and caregiver strain in what many describe as the ‘Silver Tsunami’ of a rapidly aging population.”
She said the organization supports The Guardian Network because it strengthens coordination during the most critical moments when vulnerable individuals go missing.
“The Guardian Network aligns directly with our work to stabilize families and protect vulnerable communities,” West said. “When vulnerabilities are reduced, safety increases.”

United Way collaborates with certified partner agencies across the Virginia Peninsula that focus on homelessness prevention, youth development, domestic violence response, aging services and housing repair. Those organizations would continue serving in their core roles, providing safe housing, trauma-informed care, mentorship, caregiver support and case management, while the network enhances coordination and awareness.
“The Guardian Network enhances coordination and awareness, while nonprofits provide the direct relational support that protects individuals before, during and after crisis events,” West said.
The concept also includes a second phase of development that would establish a standing advisory committee composed of survivors, impacted family members, nonprofit leaders, victim advocates and public safety professionals. A third phase would focus on identifying and allocating resources to support coordinated response efforts in collaboration with law enforcement, including ensuring necessary logistical supplies are available during active situations.
The immediate focus is Virginia. If successful, supporters say the model could be scalable to other states seeking to strengthen coordination in missing-person cases.
Reid said the goal is clear.

“A stronger safety net. Better coordination. And helping bring loved ones home,” she said. “Everyone deserves to come home.”
