Speculation ahead ...
If DeOrr was abducted, knowing the *correct* time of arrival could help bring in tips. If someone saw something hinky or strange on Thursday evening, they might blow it off since as far as anyone knew, the family wasn't even there until Friday. So clearly, according to this imaginary witness of mine, there could be no connection between weirdo creepy stalker person and that little boy who went missing Friday. No, DeOrr wasn't taken on Thursday, but that doesn't mean a predator wasn't lurking somewhere that evening or doing something strange.
I don't think it matters what DK and JM were off doing (fishing, finding minnows, exploring, whatever), and I don't think it matters all that much whether GGPA sneezed or closed his eyes or fell asleep in the grand scheme of things. The parents weren't there with DeOrr for a brief period, and GGPa wasn't watching him for whatever reason, and that's what we need to know as far as that goes (moo). But it absolutely does matter -- imo -- when they arrived and it absolutely did matter -- imo -- to the public if LE wanted tips from the public.
That's a lot of speculation and what-ifs. And tbh, I think that stranger abduction is about the least likely scenario -- but on this point, I believe very much that their time of arrival should have been corrected immediately. I can't help but wonder why LE didn't do that. By their own admission, they are not ruling out a stranger abduction, so why not correct the timeline and maybe get more tips? *
*Although as I say that, I wonder if it had something to do with them being snowed under a blizzard of nonsensical tips ...
