I'm thinking you should have let the camera get his picture, then at least you would have some evidence. As they say a piture is worth a thousand words. I hate to say it but there is a good chance your stuff may not be there, they know where it is now. they will most likely come back at night and get it when no one is around. I've had more stuff stolen off of my private property than I have hunting public land. I've left hang on stands in the trees for a couple of seasons on public land before. It got so bad on my private place that I wouldn't leave them there over the weekend.

Good Luck.

As a side note, I always carry a sidearm when in the woods, unless it is during bow only season. Not only do you have to worry about whackos but depending on where you live, some of the wildlife is not very friendly.
