RE: lost a deer this morning
If you decide to go after the animal . . . PLEASE do not go alone. Others with you could be the wisest thing you could do. More individuals that witness and support your ethics takes it out of the "He Said-S[H]he Said." One or more additional whitness' would be priceless.
If the land orwner takes the deer . . . I would think he could be charged with illegal posession . . . unless he can get a tag.
