Remember the NUT in Home Depot....remember the cliche about dragging a 100 bill thru a trailer park...HELL think we have NUTS NOW!!!!
Bet ya dollars to donut holes...this NUT is a "loner" who will be later described as "a quiet guy, kind of stayed to himself"... serial killers do BLEND in...remember Gacy...hell Jimmy Carter's wife had a pic taken with him...he was very involved in polictics...HELL his wife lived in the same house with DEAD people buried under the HOUSE!!!!
Throwing gobs of money out into the public arena is only gonna make a ka-gilion nuts come forward...hell I suspect with the FReepers alone the FBI has "enough help"! LOL!!!
You forgot the "nice", "polite", "well mannered" and "I can't BELIVE..."part...as well as might be added part to this case IF and that's BIG IF it's ever solved: "well dressed" and maybe "attractive".
