The Clue is in two places. In the infamous PM'S that were sent to Det. Duffus and one BIG clue left at the scene where Caylee's remains were found.
I have been hinting on here and elsewhere for months what one clue was and everybody was so intent on what has been alleged that I have said, that they, in their bias missed the clue that was right in front of them.
The first big clue is in the PM.
THIS IS A CLOSE UP OF THE USERNAME OF THE PERSON ON THE "OTHER END" OF THE CONVERSATION:
NOW, IN THE NEXT SHOT PAY ATTENTION TO THE LETTERS UNDERLINED IN RED:
NOW TAKE A LOOK AND SEE IF YOU NOTICE INTERESTING IN THE NEXT TWO IMAGES
THIS FIRST PHOTO WAS TAKEN ABOUT 100 FEET FROM WHERE CAYLEE WAS FOUND. 
THIS SECOND SHOT SHOWS MORE OF THE FENCE ALONG WITH SOME OF THE MATERIALS FROM THE CAYLEE MEMORIAL. FROM WHAT I HAD LEARNED ON THE DAY THIS PHOTO WAS TAKEN, THOSE LETTERS APPEARED SOMETIME SHORTLY AFTER CAYLEE WAS FOUND, A COUPLE OF WEEKS EARLIER.
NOW SEE IF YOU NOTICE SOMETHING INTERESTING ABOUT THIS IMAGE AND THOSE ABOVE.
STILL STUMPED?
Check out the various blogs, stream and youtube sites of the username above. You will find this fellow is one for pranks and a bit of off beat " humor. The kind of prankster alleged to have impersonated IRS agents and FBI agents along with other interesting "characters."
He has even been alleged to have made what are known as "soundboard" calls and other "prank calls" broadcasting these calls live on his USTREAM.TV stream site as well as uploading them onto his youtube.com site and other sites he had set up.
Let us examine the Username above this way:
Short (S)T
Bus (B)
Dude(D)
The username is written in a way as to "hide" what could be his "monogram" that he most commonly uses IE:
SBD.
Now one of three things are possible here:
A: Mr. Short Bus Dude of Clearwater, Florida, either by himself or in partnership with one or more persons "created or partook in the famous PM.
B: Someone ELSE used the username in such a way as to implicate an innocent SBD in the PM hoax.
C: Or it was just a remarkable coincidence.
I really, really doubt it was C.
Now this would be nicely cleared up if Det. Duffus would at least PRETEND to know what the hell he was doing and at least TALK to Mr. Short Bus Dude, along with the brain dead individual who sent HIM (and not to law enforcement by the way) the PM's to be certain that someone WHO MAY HAVE SOMETHING TO DO WITH THE FATE OF CAYLEE does not go scott free while Casey Anthony winds up assuming room temp and pushing dasies some years or so down the road courtesy the State of Florida.
