Horse soring is the practice of applying caustic chemicals directly to the horses' legs and then tightly wrapping them with plastic wrap and duct tape to cook the harsh substances into the flesh. Then metal chains are placed around the sensitive area, causing excruciating pain with every step. Pain-inducing shoeing methods and barbaric devices are also commonplace soring techniques.
On the day of the raid on Wheelon's barn, it looked like a medieval torture chamber. The walls were lined with heavy logging chains and weighted shoes known as stacks. A shelf was packed with blistering agents, ranging from mustard oil, cinnamon oil and WD-40, to multiple unmarked substances, including one unlabeled jar containing a chemical mixture described by a stable hand as "tea, a powerful concoction of 10 cubic centimeters of cinnamon oil and approximately 200 cubic centimeters of kerosene."
