Cayuga,here in Michigan,it is illegal to put your tag on a deer you did not shoot/kill.Also it is illegal to trespass on private property to track/recover a deer you have shot.Unless the land owner gives you permission to recover the deer,you are out of luck.However if you know the deer is dead,the land owner cannot claim the deer as his since he is not allowed to put his tag on a deer he did not kill.Calling the DNR and proving you killed the deer would be hard.Best case scenario would be the DNR would claim the deer and donate it to the food bank.
