There's the driver lying about it saying it was discussed on Thursday until the police showed the driver he had to have known by at least that Wednesday. Also there's knowing how banks work, which I as an ex-banker (BOA no less) can speak from personal experience just how things were handled on the mortgage side with anti-money laundering training as AML gets beat into all BOA's employees heads even if you're not in the consumer or commercial bank side of things. The BOA training is actually specific on reporting unusual transactions plus withdrawing over certain amounts automatically requires government forms to be filled out by the bank. The branch manager could have turned on a dime for this unusual and federally mandated reportable request and operated counter to BOA policies and just instantly started shaking the money tree as soon as the doors opened, but if that branch manager handed over $40K in cash in only about an hour, they're probably an ex-branch manager now.
Driver (W1) got a text on Wednesday which he didn't tell police about during the first interview. Presumably it was after 6 pm (although affidavit doesn't say that). Bank would already be closed.
