So sorry for your loss! The trail camera will be interesting; you will probably be amazed at who's visiting, especially at night.
Your run isn't secure enough for night time, especially. I hope your coop is safe so the birds can be inside while you improve your security. Hardware cloth over every opening, a hardware cloth skirt around the base unless it's all concrete, and good complicated door latches. Weasels, rats, and raccoon arms can all get through cyclone fencing, but it's useful for other critters.
Your current varmit will return! Live traps baited with cat food, or chicken, or for raccoons, peanut butter or marshmallows, may get something. Weight the trap down with a concrete block so it can't be moved or tipped over. Only trap if you will shoot the trapped varmit!
