Police interviewing Au pair in love triangle double homicide

A Virginia au pair pleaded guilty Tuesday to manslaughter in connection to the 2023 murders of her employer's wife and another man.

Juliana Peres Magalhaes' employer, Brendan Banfield, was charged with murder last month in the case -- a year after Magalhaes was arrested and charged.

Prosecutors said Magalhaes and Banfield began an extramarital affair in August 2022, and by the fall of that year, Banfield expressed his desire to "be rid of" his wife, Christine Banfield, according to the plea agreement obtained by ABC News.
