@crmnallyobsessed: Former IRS agent Brendan Banfield took the stand in his murder trial on Wednesday, admitting to past affairs but denying he plotted to kill his wife with their au pair, Juliana Peres Magalhães. Prosecutors say Banfield and Magalhães used a fake online profile to lure another man to their home in February 2023, where they staged a double murder of the unsuspecting man, Joseph Ryan, and Banfield's wife, Christine. Peres Magalhães has already pleaded guilty to manslaughter and testified against Banfield, saying he killed both Ryan and his wife. Brendan Banfield will continue testifying on Thursday.
