Summary
Iris Dalley-Graff, Forensics Analyst, took the stand in the murder trial of Brendan Banfield, the former IRS agent charged with four counts of aggravated murder in the deaths of his wife Christine Banfield and Joseph Ryan. Prosecutors allege Banfield and the family's au pair, Juliana Peres Magalhães, lured Ryan to their Herndon home through a fetish website and staged the killings as a home invasion.
The defense argues digital forensics contradict the catfishing theory and that investigators who disagreed were reassigned. Banfield faces life without parole if convicted. The four-week trial continues in Fairfax County.
