Antonio de la Maza was one of the conspirators in the assassination of Rafael Trujillo. He used Juan Tomas Diaz's shotgun to shoot Trujillo while he was driving at night to see his wife. De la Maza was killed shortly after coming out of hiding, just a few days after the assassination.

De la Maza's brother Octavio had been killed by Trujillo's henchmen in the context of the Galindez case.
