A search for a herd of missing horses in the Ozark Scenic Riverways area of Shannon County has failed to find them. Park spokesman Ben Clary says the search began after three of the horses were shot to death earlier this month. Clary thinks the horses might have joined other herds in the area, or might be scattered into areas that haven’t been checked yet. The county sheriff has gone up in a highway patrol helicopter looking for the surviving animals but hasn’t found anything. He says there are no suspects in the shootings.
