No, the stock options as bonuses have to be publicly reported. It maybe obscure to the average citizen, but that kind of stuff is standard news fodder for stock analysts and could have been reported any number of trade publications.
It it was not a secret or private information. Did the stock value even flucuate between the 1st and 4th quarters of 96 that would have substantially changed it's rounded out value of $118,000?
I don't think the writer of the note pulled the number out of a hat, but I also don't think it indicates Ramsey involvement either. Only that the note writer/killer had been studying their family and may have used the number to indicate exactly that.
The killer may not have been somebody the Ramseys knew, but it most certainly was somebody who had gotten to know them.
Sure, if you want to think a pedo who wanted to kidnap or molest or kill JonBenet stopped first to look up on Edgar the insider postings, go right ahead.
I just think that's bull. Several adults in that household had a pretty good idea what the round number was.
