At 11:48 a.m. on May 24, Rubin Ruiz, an officer with the Uvalde school district police department, arrived in the hallway of the Robb Elementary School and informed officers on the scene that his wife, Eva Mireles, had called and told him she had been shot in her classroom at the school. Ruiz, who was armed, apparently told the officers he was there to enter the classroom and attempt to save his wife’s life.
