Mr. Mike you live 30-40 minutes from any response time, thats if anyone is freed up on calls, including ambulance. You moved there to have your piece of heaven, to hunt. you gotta think . . . they live there to pull the $h1t they're doing and no cops around (whens the last time you seen a patrol unit?
going to the residence . . . your stepping in his kill zone, his domain, and if he's an Alpha person you're not going to make a scrape in his yard- deer talk
I'd play to his ego, be dumb, let him know you're dumb, step up your surveillance double or triple cameras, hidden. don't say a word even to the wife,family or neighbors. The first time was food, a needy person maybe? this time they mocked you and took your camera (evidence) . . . in time you'll get him . . . its an all different type of hunt now.
I deal with this on a day to day basis, this is how i make a living.
