BANFIELD TRIAL DAY 7: Daughter Asked Au Pair "Can I Call You Mommy?" Hours After Mother's Death — Detective Reveals Pressure From Supervisors

Two bombshells dropped on Day 7 of the Brendan Banfield double murder trial in Fairfax County, Virginia.

First, the defense landed a significant blow. Homicide Detective Leah Smith testified that leadership pushed the catfishing theory before evidence supported it. According to Smith, she was told: "There are two theories and you need to get behind the right one." Defense attorney John Carroll revealed a forensic analyst was removed from the case after theorizing that Christine Banfield — not Brendan — was communicating with Joseph Ryan on the fetish website FetLife. The defense argues investigators had tunnel vision from the start.
