The illegal killing of an elk west of Hot Springs has Game, Fish and Parks conservation officers looking for the person responsible. Officer D.J. Schroeder says a landowner along U.S. Highway 18 found the carcass late last week. Authorities determined it had been shot with a high-caliber rifle. Schroeder says authorities are pursuing a couple of leads and also asking the public for help. People with information might be eligible for a reward.
