But Banfield testified he and Magalhães did not plot to kill his wife and another man in the months that followed, despite what prosecutors suggest. “That is absolutely crazy.”Banfield is charged with aggravated murder in the killings of his wife and Joe Ryan. Earlier in January, Magalhães testified that she and Banfield had created an account in Christine Banfield’s name on a social media platform for people interested in sexual fetishes. His testimony comes as John Carroll, Banfield’s attorney, spent much of the trial scrutinizing Magalhães' motives in the case. The former au pair was initially charged with second-degree murder in Ryan’s killing, but has since pleaded guilty to a downgraded manslaughter charge.
