Just days before the academic year was supposed to end and summer break was to start, teachers and students at Robb Elementary were attacked in their own school. They died in their classroom, unable to escape the gunman.
Two teachers and 19 students were killed at the elementary school in Uvalde, Texas, making it the second-deadliest school shooting in U.S. history. At least four others were injured.
Here's what we know about the victims who died:

Describing his daughter as being full of life and love, he added, "It hurts us to our souls."
Makenna Elrod, 10
Brandon Elrod spent hours looking for his daughter after the shooting, and when he wasn't able to locate her in the rendezvous point or local hospitals, he wanted to get in touch with the nearest funeral home.
"I don't know what this world's coming to," Elrod said in a brief interview with ABC News.
Jose Flores Jr., 10
"He was always full of energy," his father, Jose Flores Sr., told CNN. "Ready to play till the night."

"Our Ellie was a doll and was the happiest ever," Garcia wrote. "I was gonna DJ for her at her party like she wanted me too!!! Mom and Dad love you never forget that and please try to stay by our side Amor!!!!"
Irma Garcia, fourth-grade teacher, 48
Garcia taught at Robb Elementary for more than 20 years, spending her entire career at the school.
"I love to BBQ with my husband, listen to music, and take country cruises to Concan," she said, referring to the popular summer getaway area that's about 20 miles north of Uvalde, along the Frio River.
For the past five years, Garcia had been a co-teacher at Robb, working alongside Eva Mireles, the other teacher who died in the shooting.
She had four children – two daughters and two sons – according to her bio on the school website. Garcia and her husband, Joe, were married for 24 years, she said on the site. A family member says that Joe had a fatal heart attack on Thursday, two days after his wife's death, the Associated Press reports.
Uziyah Garcia, 8
Manny Renfro told the Associated Press that his grandson was "the sweetest little boy that I've ever known."
He last came to visit during spring break.
"We started throwing the football together and I was teaching him pass patterns. Such a fast little boy and he could catch a ball so good," Renfro said.
"There were certain plays that I would call that he would remember and he would do it exactly like we practiced."
Amerie Jo Garza, 9
"You did not deserve this my sweet baby girl," her mother, Kimberly Garcia, wrote on Facebook. "Mommy loves you, mommy can't sleep without you."
Her father, Angel Garza, wrote, "My little love is now flying high with the angels above. Please don't take a second for granted. Hug your family. Tell them you love them. I love you Amerie jo."
Berlinda Irene Arreola told The Daily Beast that her granddaughter — who leaves behind a 3-year-old brother — was fatally wounded while trying to call 911.
"So the gunman went in and he told the children 'You're going to die.' And she had her phone and she called 911," she said. "And instead of grabbing it and breaking it or taking it from her, he shot her. She was sitting right next to her best friend. Her best friend was covered in her blood."
Jayce Carmelo Luevanos
Luevanos loved to make people laugh, his grandmother, Linda Gonzales, told the Daily Beast.
His cousin, Jailah Silguero, was also killed in the shooting.
"They were just so sweet," Gonzales added. "They were sweet kids and lovable. What can you say about little innocent kids?"
Xavier Lopez, 10
Lopez's mother, Felicha Martinez, confirmed to The Washington Post that her son was among those killed in Tuesday's attack. (The family has also created a verified GoFundMe for funeral expenses).
She said he loved dancing and sports, and that his favorite school subject was art. He was a bright light for their family with a smile that could cheer anyone up, she added.
Lopez received a certificate at his school's honor roll ceremony just hours before the shooting. Martinez said she told him she loved him and hugged him goodbye, not imagining that would be the last time she saw him.
"He really couldn't wait to go to middle school," she said.
His cousin, Lisa Garza, asked for prayers on Facebook. "My little cousin lost his life today to this senseless act of a shooter at his school," she said.
Tess Marie Mata, 10
"My hope was that she was lost or hiding somewhere in the school," her older sister Faith told The Washington Post. They didn't find out the truth until late the night of the shooting. She told The Post that Tess had been saving money for a family trip to Disney World next year.

Eva Mireles, fourth-grade teacher, 44
Mireles was remembered in a Facebook post by her daughter, Adalynn Ruiz, as "the half that makes me whole."
"My best friend, my twin was taken from me," Ruiz said. "Thank you for loving me in the best ways and for raising me to become so strong. Everyone who knows you knows how outgoing and funny you were and I will miss your laugh forever."
In a bio on Robb Elementary's website, Mireles said she had a "supportive, fun, and loving family" that included three "furry friends." She said she enjoyed running and hiking "and now you just might see me riding a bike!!"
Mireles co-taught with Irma Garcia, who also died in the shooting.
