, known only as Juanito, was caught heading back to Sonora with a load of stolen silver bullion, so Poston had him executed as an example to other thieving employees. The silver was never recovered and was reportedly buried by Juanito somewhere near the mine. Juanito's death only made the matter worse. Within the next few nights, Mexicans stole "''whatever they could''" and took the property to Sonora, where several Mexican outlaws heard the story of the buried treasure. The outlaws immediately headed into Arizona for the mine. Once there they won the support of the Mexican employees and destroyed the mine in hopes of finding the silver. After failing to find it they tortured and murdered John Poston and two German miners. As of 2023, nobody has ever found the treasure. When the massacre was over, the outlaws left for Mexico and the mine was rebuilt. By 1864 a walled stone
