For the second time in six years, Robbie and Julie Dunn have found one of their horses shot dead at their Panhandle ranch. The Dunns said someone shot their 28-year-old gelding Boss in the side of the head with a small-caliber weapon the morning of Nov. 18. The bullet did not kill the horse for hours, and its suffering and collapse were captured on surveillance video. Julie Dunn said she found Boss lying on his side dead near the barn at their ranch on Old Church Road when she went to feed him and his five stablemates that afternoon.
