Live updates: Defense grills investigators on ‘catfish theory' in Banfield trial

What to Know

  • Brendan Banfield, a former IRS officer, is accused of killing his wife, Christine Banfield, and a stranger, Joseph Ryan, at the Banfields’ home in Fairfax County, Virginia.
  • Prosecutors say the killings were part of a calculated plan so Brendan could get Christine out of the picture and start a new life with his family’s au pair, Juliana Peres Magalhães.
  • Peres Magalhães pleaded guilty to manslaughter for her role and agreed to cooperate with investigators. She said Brendan created a fake profile for Christine on a sex fetish website to lure a stranger to the home and pin his wife’s murder on him.
  • The defense has argued the digital forensic evidence doesn’t back up the au pair’s claims and that investigators pursued their “catfish theory” without proof. But a detective who investigated the digital evidence said that although the “zeroes and ones” don’t change, he had to take the au pair’s story into account.
  • That same detective testified yesterday that he was re-assigned against his will. “It was related to my work in the Banfield case,” he said.
  • Brendan has pleaded not guilty to all charges.
