Prosecutors claim that a double homicide at a Virginia home is linked to a fetish plot, an affair, and a gun range.

An alleged affair and a fetish website connection were revealed this week in the case of a Virginia au pair who prosecutors say was involved in a double homicide at the home where she worked.

Prosecutors also said at a probable cause hearing on Monday that Juliana Peres Magalhaes and Brendan Banfield visited a gun range together before his wife, Christine Banfield, was killed during a double homicide at their home in February 2023.

Brendan and Peres Magalhaes have said Christine was killed by a stranger named Joseph Ryan, whom they shot after Ryan stabbed Christine.

It’s part of a bizarre story that led to a murder case against Peres Magalhaes, which a judge ruled on Monday can proceed to a grand jury this month, NBC Washington reported.

Brendan and Peres Magalhaes purchased the Glock used to shoot Ryan on a trip to a shooting range on Jan. 28 of last year, weeks before the incident, WTOP reported. 

In court, Commonwealth Assistant Attorney Eric Clingan said the gun was used to “eliminate the only existing witness,” according to the station. 

Gill previously questioned why Brendan only shot Ryan after he stabbed his wife several times and has questioned whether Peres Magalhaes really shot the man at Brendan’s behest, the Washington Post reported. 

Ryan Campbell, the nanny’s lawyer, said in December that his client acted in self-defense, according to the newspaper: 

“He had just stabbed Christine Banfield,” Campbell said. “It seems perfectly reasonable that a second shot would be fired to make sure that he’s not a threat to Brendan or Christine or Juliana.”

Campbell could not immediately be reached for comment.

Brendan invoked his Fifth Amendment right when questioned on the stand at Monday’s hearing, WTOP reported. To date, according to the outlet, he has yet to speak with authorities about the fatal events of Feb. 24 last year.

Brendan had no comment outside court on Monday, NBC Washington reported.
