What we know about the victims of the Texas school shooting in Uvalde so far

A fourth-grade teacher, several sets of cousins and a 10-year-old boy whose family called him "the life of the party" were among those killed in a mass shooting at a Texas elementary school, ABC News has learned.

At least 19 children and two teachers were killed after a gunman opened fire at Robb Elementary School in Uvalde, west of San Antonio, on May 24, according to the Texas Department of Public Safety.

The alleged gunman -- identified by officials as 18-year-old Salvador Ramos, a student at Uvalde High School -- is dead, authorities said.

"When parents drop their kids off at school, they have every expectation to know that they're going to be able to pick their child up when that school day ends. And there are families who are in mourning right now," Gov. Greg Abbott told reporters.

Here's what we know about the victims so far.

Layla Salazar, 11

Layla Salazar was among the victims in the shooting, her father, Vincent Salazar, told The Associated Press.

He would play "Sweet Child O' Mine" by Guns N' Roses as he drove her to school each morning and Layla would sing along.

"She was so happy," he said. "She was so free of life. She was sweet."

Tess Mata, 10

The family of Tess Mata confirmed to ABC News that the 10-year-old was killed in the shooting.

With every school shooting that plagued the country, the family never thought it could happen in their small town.

"Every time we would see another mass shooting on the news we would say, 'that won’t happen here,'" Tess' mother, Veronica Mata, told ABC News. "That could never happen here. Not in Uvalde."

Veronica Mata said now her daughter is gone and she "will never get to hold her again."
