Brendan Banfield, the Virginia man convicted in the killings of his wife, Christine Banfield, and a stranger, Joseph Ryan, in an elaborate double murder plot, was sentenced to life in prison Friday.⁠ ⁠ Prosecutors say Banfield was having an affair with the family's Brazilian au pair. She pleaded guilty to manslaughter and testified against her former boss-turned-lover, saying they posed as Christine online and lured Ryan to the home, making him think he was going there to carry out a consensual rape fantasy.⁠ ⁠ #TheAuPairAffair #BrendanBanfield #Herndon #FairfaxCountycourt
