Prosecutors say a Virginia man, having an affair with his family’s Brazilian au pair, used an elaborate scheme to lure an unsuspecting man to the house as part of a plan to kill his wife. Brendan Banfield is charged with aggravated murder in the February 2023 killings of Christine Banfield and the second man. Brendan Banfield has said he and the au pair found the man stabbing Christine and shot him. Some media have dubbed the case the “au pair affair." The au pair, Juliana Peres Magalhães, pleaded guilty to manslaughter in 2024. Banfield’s attorney says he is innocent. He says detectives who disagreed with the theory that the pair lured Ryan to the house were transferred.
