Missy, do we know that it didn't show up on his computer? Also, you make a good point, but I'm not sure the prosecution would necessarily think of showing that history. The QB accounts, from what I can remember, weren't linked to the bank. I would have to say, he'd had to have gone online and looked it up. Unless, maybe he received a bank statement in the mail?
I do think that the most likely way he would have accessed his banking information, from what we know about the McStays, would have been online. I do think you could have done it on a phone back in 2010, although I'm sure it would have been more cumbersome than the computer. I'd bet computer, and if there's no evidence of it on that, I'd like to know when bank statements were mailed out.
And: I apologize in advance if none of this makes sense. So tired here, but appreciative for all the amazing posts!
