If you saw my desk this morning before I did some filing, anyone could have walked in and known just has much money was in the stock market, bank account, and a recent refund without doing too much looking.
I suspect his desk looked like mine and the perp saw the amount of bonus and used that in the note paper from the top of the desk. I have a yellow pad next to my keyboard I keep notes on and sometimes it is white.
The Ramsey's did not write the note according to the handwriting experts that were on-- John Ramsey was completely ruled out and her score was so hire to not have been admissable in court. They did say the paper came from the desk which led me to believe the amount of the bonus could have also on top of the desk.
Seems logical.
then why wouldn't John Ramsey have told the police that? he could simply have shown them he had a letter or tax form on his desk, that showed the amount of the bonus - eliminating one of the strange issues surrounding this case regarding how the killer knew how much to ask for in the ransom note.
