I've read some of David Paulides books about missing people, plus I've been here on Websleuths for years, and one thing that is factual is that when a child or anyone is attacked by a wild animal, there's going to be some kind of evidence somewhere. Blood, bloody clothing, shoes, something. Animals are not "neat" when they bury a body.
In the case of Rainn they found no blood or evidence, but that was because she was alive after all! And I did not think that was possible - but just as Paulides says - police should look outside the 2-mile limit of where they think a toddler can go. Sometimes they just give up too soon. Rainn was found in sight of the road, I believe. Just incredible.
Here in TN there have been bear attacks on small children. There was one about 10 years back when a bear attacked a family of three on a trail in early spring just as the hungry bears came out of hibernation. The kids had been eating hamburgers and there was almost no one else at this campground. But that does remind me of Deorr who may have wandered or fallen down near the creek.

The mother fought the bear and saved the little boy, but the little girl ran away. Later the body of the little girl was discovered and authorities said she was killed by a bear. There was evidence around, and blood, and torn clothing, and the body was there - apparently not eaten. Immediately they tracked a bear, set traps, caught a bear. But they ended up killing the wrong bear.
It took them days to find the bear that actually killed her, even though they started looking right away.

So my point is that even if they had some cougar scat or bear scat right away, or if someone saw a wild animal right beside the campground, it might not prove anything without DNA, or blood, or clothing, or shoes, or something. There's no evidence of any kind of attack that we know of.
This case is strange, and I don't know what is going on. If the FBI has something to prove it's an animal attack, I would really like to hear what that is.
