While I do not doubt that both TM and LP do WANT to find Caylee, the two men and their motives are very different. TM is searching with the blessing and request of LE and is using the information and facts that they have willingly supplied him in order to determine WHERE to search. LP is using hunches that are in NO WAY based in fact or on LE information. He jumps from one hunch to the next minute by minute.
Since LP has NOT been approved or sanctioned by LE, he is very much in danger of jeopardizing the case against Casey. Any type of evidence that he might locate or find would never hold up in court because he has made it clear that he is determined to condemn Casey. Tim has been adamant that all searchers be instructed on procedures, that they do not speak with media, and that they may not make calls or take photos of the search. LP has allowed and encouraged photographers, television and print media and untrained lookiloos being in the middle of everything that he does.
One man is in this to find a child and to find and preserve correctly any evidence which might be around. The other is in it to find Caylee and then do every talk show interview that he can get his face into.
Tim is needed and wanted elsewhere. He is wise enough to realize that no one single missing person is more important than another. If he can go to North Carolina and perhaps find two or three or four, it would be unconscionable to waste his time, money and resources in Florida on a hopeless search. Caylee or her body could be anywhere, there is no area to which it can be narrowed down to search any further.
Tim is as disappointed as anyone could ever be to leave without finding this child. However, he is also wise and experienced and needed elsewhere. If he says that he has searched all areas requested by LE in this case, there is nothing more for him to do. It is impossible to search hundreds of square miles of scrub areas when there is NO indication that Casey or anyone else who had Caylee was ever there.
