Workers were herding horses into a makeshift chute being used to guide the animals into a horse trailer. Two of the workers were trying to close the chute by pivoting one of the metal panels across the entrance while the other attempted to keep the animals from escaping. One horse slipped through a gap as one of the metal fence panels was being dragged into position. A second horse tried to leap the dragged panel, which broke when the horse hit it. The broken panel knocked a worker to the ground and the horse rolled on top of him. He died from serious head injuries. The government’s preliminary findings indicate the direct cause of this incident was that the metal fence panels in the chute weren’t capable of withstanding the force applied against them.
