Scooby doo-ish = Going to take a stoner and his giant talking dog and a gay and a lesbian friend and a floozy to figure this out with the info given, By posting the pic and showing the sheriff of the "samsquantch man", as he has been dubbed in various NDA circles my sources have confirmed, you have done almost all you can do short of posting it in the paper.
I'm guessing what some may say is the suspect part as follows(me it seems legit enough or I don't really care that much if you are trollin, i just know ndbowhunter had a similar deal happen last year and nothing ever really got resolved, but he had shit stolen as well)
So a few days after you get the pic which you said were taken on Monday 23rd, after season on your neighbors camera. You post this the 28th, saying this guy trespassed on your property too, then within 2 days of it being posted the camera is gone? You said this guy trespassed across your land and onto your neighbors. Without knowing how you know this for sure makes people wonder. Anyways obviously there is a way to drive to this spot if your neighbor got a 70's camper down there. So the chance that this guy drove there is possible atv,utv,truck whatever. You or your neighbor don't know the guy so he is trespassing no doubt there, since season is over even if he is pursuing wounded game after season(deer) it is a trespassing charge.
The fact this guy is wearing snow camo when there is no snow plus a blaze orange scarf tells me he isn't trying to be overly sneaky, that and it is definitely light out when he is there and he doesn't have a weapon and he is burning heaters as he walks makes me think he isn't hunting or a shitty hunter/trespasser/poacher. Nothing has been stolen besides this camera as of right now? And it wasn't stolen until after it was posted on NDA right? So either the guy is sub_elect in a samsquantch outfit and he seen his mug on NDA and went back in there and stole it and destroyed evidence or it was the hotel desk clerk the whole time as wags stated.....
Basically it is a shitty deal and someone is trespassing but other than the picture you really don't have anything else besides the fact the camera is gone now. The former FBO sleuths like more, is that picture bigger than what you posted I mean most trail cam pics I've seen have a wider view than that maybe get the original sent to sheriff and they can use what they got to zoom in on the reflection in the window of the camper to see if the white truck is there or something. I don't think anyone is straight up calling you a "toby" yet I just think a couple of people are confused on what is going on in this whole Scooby doo episode.
