Alleged killer husband Brendan Banfield had special triple-glazed soundproof windows installed in his house to muffle the screams of his wife and a stranger while they were murdered, the jury at his trial in Virginia heard Thursday.
A window factory salesman testified that he had spoken with former IRS agent Banfield about the windows when they were installed, not long before he is alleged to have murdered Christine Banfield and Joseph Ryan at the house in a leafy Washington, DC, suburb.
He described them as “30% better in energy savings and noise level” in his testimony during the trial for Banfield, who is accused of masterminding a twisted double-murder rape plot so he could be with his Brazilian au pair, with whom he was having an affair.
“When someone goes to a triple pane, that’s another level. And that is a type of level where they’re trying to do more than just protect the house from the sun,” the salesman added.
Earlier this week, Banfield’s au pair, Peres Magalhaes, testified that the married father had the home’s windows replaced so neighbors wouldn’t hear screams during the murders.
Magalhaes claimed Banfield had her test out the windows by screaming to see if she could be heard from outside.
