The resolution honors the life and contributions of Cacique Jose Sierra Sr., who passed away on August 16, 2025. Born in 1943, Sierra dedicated his life to serving the Tigua people of the Ysleta del Sur Pueblo tribe in El Paso, holding various leadership roles including governor, sheriff, tribal judge, and ultimately cacique, the highest spiritual authority within the tribe. His efforts were instrumental in establishing significant community resources such as the YDSP Cultural Center, a health care clinic, and securing federal recognition for the tribe, which included a landmark U.S. Supreme Court ruling affirming their gaming rights. Additionally, he played a vital role in the repatriation of sacred artifacts from the Netherlands.

Beyond his tribal leadership, Sierra had a successful career as a location scout for the El Paso Convention and Visitors Bureau, where he showcased the region's landscapes in film and interacted with notable figures. He is remembered for his deep commitment to his family, including his wife Irma, their five children, and a growing lineage of grandchildren and great-grandchildren. The resolution expresses condolences to his family and acknowledges the lasting legacy of wisdom, generosity, and strength that Cacique Jose Sierra Sr. leaves behind in the Ysleta del Sur Pueblo tribe.
