For the 12 years of his life, the Emperor roamed Exmoor in southwest England, a wild swathe of heath and woodland that has drawn hunters for 1,000 years.

He is reported to have been shot two weeks ago near a main road linking the towns of Barnstaple and Tiverton. Local people were speculating furiously Tuesday about the identity and nationality of the hunter: was it an American, a European, or a wealthy Briton who saw the picture and decided he wanted those magnificent antlers on his wall?
