"Any local land surveyors you know that could make an obvious show of checking some property boundaries. Ag company rep
looking over your property, maybe a real estate person...???
Group of conspicuous guys doing fence work unknown to him just to get other people on his camera that he doesn't know.
Basically give him doubt about who called him in."
This is a good suggestion here.
Getting a few other people on camera,, surveying the area for whatever reasons can create a bit of confusion as to who might have turned him in. HOWEVER,, it may be a bit "suspicious" if strangers appear shortly after the initial discovery.
It would be even better if the "strangers" were seen, and at the same time,, they get on the cell phone & call the local LEO's & whomever they can. WITHOUT leaving the area. That way,, the LEO's can arrive, and start an investigation.
But before "strangers" try & go out there,, you need some time to elapse,, to where you become less of a suspect to this FELON, so he may not think you were the one to initiate the investigation.
I FULLY understand the pause of action for the potential fear of this FELON doing his arson thing to you, or your family. Having had a felon commit arson upon my family in 1978,, (burning down my Dad & Mom's business,) makes me just as cautious. The LEO's in our case were never able to actually catch the thugs who did this,, but we all had enough circumstantial evidence to know who was responsible. I was in the Army when the fire happened,, and upon my return in late 1979,, it took me a few years to get some direct info that pretty much proved to me who was responsible.
Caution is a good thing right now for this situation.
