This is so devastating to hear.
I was closing up for the night to settle down to watch the A's miracle run and checked each thread I had open before closing it. I was so far behind in reading on this one, I just thought to check the last page and found I just missed the report by the Sheriff about the body being found. How was his demeanor when he made the announcement?
I agree that this is probably Jessica. Men combing the fields, FBI there with lights set up. If it was a grown person, I believe they would have said that. It's been five days with cold weather so there should be more evidence than if it were in the heat of summer.
Only other possibility is another child with no clothes or distinguishing marks to identify by. Maybe body was decomposed which could also mean another child.
That abandoned mining shack sure did remind me of the hog/cattle sale building pictures posted earlier. That poster was on the right track of abandoned or empty buildings. I tried to search to find the poster's name but couldn't find it. Now that I think further didn't someone also mention mining shacks or tunnels.
At this time though, we don't know if she was anywhere near the shack. The pictures look like the search is being conducted closer to the road. The grass was so high I wonder if you could tell from the road that someone had walked through it leaving a trail?
Also another note someone earlier wondered why they were checking the wide open places instead of wooded areas. Coincidence?
I too would be interested in how she was located, when and by whom.
