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 on Tuesday, 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, 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.
Alithia Ramirez, 10
ABC News learned that Alithia Ramirez was one of the students killed.
“She was a very talented little girl,” Rosa Maria Ramirez, the grandmother of Alithia, told ABC News. “She loved to draw.”
Uziyah Garcia died in the shooting, his family confirmed to ABC News.
His grandfather, Manny Renfro, described Uziyah to The Associated Press as "the sweetest little boy that I've ever known."
"I'm not just saying that because he was my grandkid," said Renfro, who last saw his grandson when he visited San Angelo during spring break.

Makenna Lee Elrod was one of the students killed Tuesday, her aunt, Allison McCullough, confirmed to ABC News.

"Her smile would light up a room," she said. Makenna loved to write notes to her family and leave them in hidden places to be found later, her aunt said. Makenna was a natural leader and loved school. She loved going to the ranch with her dad to feed animals and ride on the ranger.

Jacklyn's father, Jacinto Cazares, told ABC News his daughter "had the biggest heart."
"My little girl was full of life and touched so many people," he said. "Jackie was the one that would go out of her way to help anyone. It gives me some comfort, that she would be the little cracker that would have done something to help her classmates in that very scary scenario."

His grandmother, Amelia Sandoval, told ABC News Tuesday night that Xavier was the "life of the party" and loved to dance and play baseball. He had just made the honor roll.
"You send your kids to school thinking they are coming home," Sandoval said, her voice choking up. "And then they're not."
"We loved him very much and he will be greatly missed," she said.
Eva Mireles, a fourth-grade teacher at the elementary school, was killed in the shooting, her aunt, Lydia Martinez Delgado, confirmed to ABC News. She had been a teacher in the school district for approximately 17 years, Delgado said.
"I'm furious that these shooting continue. These children are innocent. Rifles should not be easily available to all," Delgado said. "This is my hometown, a small community of less than 20,000. I never imagined this would happen to especially to loved ones."
"All we can do is pray hard for our country, state, schools and especially the families of all," she said.
Amber Ybarra, the cousin of Mireles' husband, called the teacher a "hero" and an "amazing mom."
"She was just very adventurous and courageous and vivacious and could light up a room," Ybarra told ABC News. "She's going to be missed."

Irma and Joe Garcia were about to celebrate their 25th wedding anniversary, their family said. The two had known each other since eighth grade and have four children together.
