What does the law say about this?
I had a friend with a similar experience; he was hunting property adjacent to a forest preserve and was not allowed by the Forest Preserve police to pursue a deer he wounded and ran into the preserves. The police threatened to throw him in jail if he pursued the deer. I have no validation but that is what he told me.
Unfortunately the law is on the property owner's side; not the hunter...If a deer crosses into private property before expiring the landowner must give permission (if he knows that you are going "sneaking" over to get your deer).
I know, the law bites; but what can you do? Not even a CPO can give you permission over a landowner for the purposes of tracking a deer.
