When the dog left the log that bridges the creek (see latest KIC video) I think she would have gone back towards the campsite.
Now there is an unwatched child and a dog not tied up.
Maybe the child and dog are playing and she runs off and he follows?
ft he walks downhill but not into the trees he would come to the ford.
200 yards that's all.
No mention is made of the dog being at the camp when VK/JA return but there is very little reference to the dog at all.
It would be helpful to know which way GGP's chair was facing & exactly what he was doing during the "unwatched" period.
I wonder why didn't the parent(s) first go down to the creek where IR was fishing when Deorr was first known to be missing?
