Last year, seven horses laden with 971 pounds of marijuana were discovered by Border Patrol agents in the Patagonia Mountains in southern Arizona. The human smugglers had fled.
“I’d get angry when I’d see the condition these horses were in,” Mr. Cowan said. “The smugglers would buy them or steal them on the Mexican side and then work them almost to death. They have horrible sores that can take months to heal up.”
