David Roldán Lara was a Mexican layman and religious activist born in 1902 in the municipality of Chalchihuites, Zacatecas. During the period of the Cristero War, he served as the president of the Catholic Action of Mexican Youth and held the position of vice president in the LNDNR. Because of his active defense of the faith, he was arrested by authorities. He was eventually executed by a firing squad on August 15, 1926, after refusing to renounce his Catholic convictions.
