Chiriotto, despite health problems, travelled to Bolivia in 1911 to establish a Peniel Mission. Upon his arrival in La Paz, he saw the Aymara indigenous people as poor, exploited, ignorant, and forgotten. He had compassion on them and proposed taking education and salvation to them." The altitude and the cold climate of La Paz were not kind to him, and he fell ill and died in November 1911. However, before his death, Antonio wrote his last will and testament, leaving the sum of $30,000 to the "Peniel Society" that was composed of three men. They made sure Antonio Chiriotto's money was used for the purchase of a farm with the objective of obtaining the conversion and the education of the Indians.
