It'd be a good way to devalue farms if you were, say, looking to buy them.

I can't imagine who else could benefit from something like this; a motive.

...not that I'm a detective or anything, but I did solve Murder on the Orient Express last night as soon as I saw the body with multiple, random stab wounds. So now I'm offering my opinion on everything, bolstered by my recent success.

I'd be looking into farmers with questionable histories.
