I had initially thought it was in the bag as well, but a report today said that the parents found the bag and “another object” while the notebook and backpack were found elsewhere by the police. The bag was also ripped open at the bottom, so no longer waterproof in the slightest.
I can accept that the area had flooding at times, but his things were there, so he got there when it wasn’t flooded - either a month ago or just recently. They started looking for him within a week, so would it have already been underwater by then? It just strikes me as odd that the parents directed them to various trails with no luck, but this one - which couldn’t have been underwater when Brian was there - is the one they neglected to thoroughly search. I mean maybe it really did flood that fast. It’s just weird, especially since they did have dive teams, and again I question how a notebook could remain intact underwater for a month.
