Sources close to the situation tell us Simpson and the FindToto.com people have exhausted every possible resource to find Jessica's precious Daisy -- last spotted in the grasp of a wild coyote.
We're told Simpson's camp used tracking dogs, scoured neighborhoods, put up posters, power-dialed neighbors and did everything else they could to find a clue ... but came up short.

Jessica still has hope ... but that hope seems to be fading pretty quickly.
