Eight students and two teachers were killed when a gunman opened fire at a high school outside Houston on Friday morning, becoming the latest casualties in a wave of deadly school shootings in the United States in recent years.
Dimitrios Pagourtzis, a 17-year-old student at Santa Fe High School, is being held on two charges: Aggravated assault to a public servant and capital murder, which means he could face the death penalty.
Among the fatalities at Santa Fe High School were a Pakistani exchange student and a substitute teacher trying to make ends meet for her family.
These are their stories.
Stone, 17, was among a group of students who blocked the door to try to prevent the gunman from entering their art classroom, Abel San Miguel, who was in the class, told The Associated Press. The shooter fired his shotgun through the door, however, striking Stone in the chest, he said.
Stone was outgoing, "really funny" and had a lot of friends, according to Branden Auzston, a 17-year-old junior at Santa Fe High.
His mother, Nicole Auzston, described Stone as a part of her family.
"We would have done anything for him," she said. "He's just a great kid."
A 17-year-old Pakistani with a bright smile, Sheikh was proud to be studying in the United States as an exchange student. The experience was organized through YES, a program funded by the US State Department, according to a Facebook post by the Pakistan Association of Greater Houston.
Surrounded by mourning friends and family at his home in Karachi on Saturday, Abdul Aziz Sheikh fought back tears as he relived his frantic efforts to check whether his daughter was safe half a world away. She wasn't returning his calls and neither were her friends. He eventually learned from the exchange program that she was among the dead.
"We are still in a state of denial. We can't believe it. It's like a nightmare," he told The Associated Press.
He said his daughter was a hard-working and accomplished student who aspired to work in civil service, hoping one day to join Pakistan's Foreign Office.
Tisdale was a substitute teacher at Santa Fe High School. She took on a second job as a server at a local restaurant after she became her family's sole income earner when her husband was diagnosed with an incurable lung disease, her brother-in-law John Tisdale posted on Facebook. The Tisdales have four children.
Christian 'Riley' Garcia
Garcia was remembered on Facebook by the Crosby Church pastor who baptised him years earlier. A photograph of Garcia, 15, taken just days before the shooting, shows him wearing sunglasses, a baseball cap and a slight smile that reveals braces on his teeth.
"Here is Riley about ten days ago writing scripture on the door frame of what was to be his new bedroom," Pastor Keenan Smith wrote. "Riley you are greatly loved and greatly missed."
After a desperate search for her missing daughter, US Army veteran Rhonda Hart posted to Facebook that Vaughan had been shot dead in her first-period art class.
"Folks - call your damn senators. Call your congressmen. We need GUN CONTROL. WE NEED TO PROTECT OUR KIDS. #Kimberlyjessica," Ms Hart wrote in a Facebook post.
My niece Shana Fisher still hasn’t been found. She was in the art room and some classmates have said she was shot in the leg. Still no confirmation on where she is. Please keep praying! pic.twitter.com/9vQzNAmMxP— Candi ♡ (@candithurman) May 18, 2018
Just one week after she celebrated her 16th birthday, Fisher, 16, was killed when the gunman opened fire on the art class, her aunt wrote on Twitter. "She should be getting her first car, not a funeral," tweeted @candithurman.
Her mother, Sadie Rodriguez, described her as "shy and sweet" with a passion for video games.
Aaron Kyle McLeod
McLeod, a freshman who went by Kyle, could always be counted on to make light of any situation, said close friend Kali Reeves, who added she wouldn't have been surprised if the 15-year-old "made a joke about getting shot" if he were still alive.
Reeves, 15, said she knew McLeod for years and became close friends with him in the eighth grade. She said he always had a smile on his face and loved to hang out with his friends.
"He was never one to be a sad or down person, he always had to joke or laugh about things," she said. "He was just outgoing and super sweet. He definitely didn't deserve this."
The other victims were named as Glenda Perkins, the second teacher to die, Angelique Ramirez and Jared Black.
