".....just biding their time till that inheritance came in."
I confess that I haven't read all the transcripts - I don't have time - however, it sounds like the prosecution may be a bit disjointed in their presentation. They hinted at a financial motive but it would seem like there would have to be more evidence (business statements, credit card bills, checking/savings accounts, etc.) Surely we'll hear more later. I don't understand why they wouldn't just present this all of this together.
Yes, they are disjointed. And the fact that each witness must be cross-examined makes it even more disjointed--but that's just how the game is played.
Here's hoping that they tie together all the finances info when they get to their closing arguments.
