The wild horses that have been targeted recently by an unknown gunman have lived and grazed freely for a long time. Ben Clary, Parks Superintendent at the Ozark National Scenic Riverways, says they started as just a few domesticated horses that were either released or got loose in the 1930’s. Since then, their numbers have grown to about thirty. Clary says they roam in small herds of 5-15 horses, monitored only by a group called the Wild Horse League. No suspects have been identified in last month’s shootings in Shannon County that left six of the horses dead.
