I am a late comer to this forum, didn't start reading till August, didn't join till September - the amount of work you all have put into this case is amazing.
I don't know what more you can do at this point. You have sifted through documents, pings, text messages, photos, etc. I think you have been as thorough as you can with the evidence and info that you have access to. I don't know what could be missing. I don't think you are missing anything - I don't think Casey will say a word until she is cornered (found guilty) and then she will come up with another story that she hopes will give her a lighter sentence, but might lead to the recovery of Caylee. I don't think the people on this web site missed a thing! You all have done the best you can with the resources you have been given. You should all be proud of the work you did - and as I said in another thread, sometimes as much as we hope for it, there isn't an answer.
