I think some of you are making too much out of the 'more bones' statement. WESH2 reported in their 'trail of bones' video that bones were found outside of the bag area, and there was speculation as to why that happened. I feel that all it means is that the searchers have found bones in addition to the ones they found this weekend. They are searching the area inch by inch, it is only logical that they will continue to find bones in an ever widening area because the bag obviously broke or was torn open at some point.
I did not see any report of a full skeleton being found - LE has been very careful to use the term 'remains'. We have to be VERY careful about believing everything we hear on the news, reporters get things wrong all the time. Sometimes they misquote people, sometimes they hear things and misinterpert them, and sometimes they just flat out report it wrong!
I am 99% confident that there is only one set of human remains at the site. There may be animal bones in and around the area, but I think when it becomes official, it will be only Caylee's remains that have been recovered. Hats off to all the people who are working so hard down there at the crime scene - you have my deepest respect and admiration for what you are doing.
