Summary

On Feb. 24, 2023, police were called to the Banfield family home for a stabbing and a shooting around 8 a.m. Brendan Banfield, an IRS special agent, told police he shot a man who had stabbed his wife, Christine Banfield. Police find Christine Banfield, nude and stabbed multiple times, in an upstairs bedroom. Nearby, they find a man named Joseph Ryan shot multiple times. Inside the house at the time of the shooting: Brendan Banfield, along with the family's au pair, then-22-year-old Juliana Peres Magalhaes, and the Banfields' then-4-year-old daughter. Joseph Scott Morgan and Dave Mack go behind the headlines to find out what really happened in a home that left a 37-year-old mother dead, a 39-year-old male stranger dead, an IRS Special agent Brendan Banfield charged with murder, a four-year-old little girl who will be raised by someone other than her mother, and the Au Pair who moved into the master bedroom, then copped a plea deal to testify for the state.
