I'm sensing that like the OP, not many of the posters read the title commitment, the attachments, or listened when the lawyer explained them at closing. OP has most of his answers to his questions in the closing packet he got, so I would suggest starting his research there. I see hunting, fishing, and recreation rights (which would include trapping) reserved in rural lands fairly frequently so the kid may have rights the OP can't do anything about even though he now owns the land. I would start by finding out if anyone reserved rights, and that would dictate my course from there. Those closing documents will then help him with boundaries, easements versus right of ways. Once he knows what's going on, then can call the authorities if he needs help. Taking and discarding evidence is not something I'd recommend to anyone no matter how in the "right" they are.
