Uvalde Texas school shooting: Teacher killed at Robb Elementary School identified as Eva Mireles; what we know about victims

UVALDE, Texas — Fourth-grade teacher Eva Mireles was killed along with at least 19 children in a shooting at an elementary school in Uvalde, Texas. The shooter’s grandmother was also killed before the Robb Elementary School attack.

Mireles worked in the Uvalde Consolidated Independent School District for 17 years, her aunt, Lydia Martinez Delgado, said in a statement.

“I’m furious that these shootings continue. these children are innocent. Rifles should not be easily available to all. This is my hometown, a small community of less than 20,000. I never imagined this would happen to especially loved ones … All we can do is pray hard for our country, state, schools, and especially the families of all,” her aunt, Lydia Martinez Delgado, said in a statement.

She was a mother and wife who loved running and hiking, according to Robb Elementary School’s website.

Xavier Lopez, 10, was identified by family as one of the 19 children killed in the school. He was in fourth grade.

His cousin said just hours before the shooting his mother had attended her son’s awards ceremony, not knowing it would be the last time she was seeing him.

Sources tell ABC News the death toll is expected to rise.

Uvalde Memorial Hospital had said 15 Robb Elementary School students were being treated in the hospital’s emergency department in the wake of the incident. Two patients were transferred to San Antonio for treatment, while a third was pending transfer, the hospital said. A 45-year-old was also hospitalized after getting grazed by a bullet, the hospital said.

Authorities have not released the names of the deceased.

“It’s pretty sad what this world’s coming to,” Elrod said.
