All 19 children killed during the Texas elementary school shooting were all from the same fourth-grade class.
A spokesperson for the Texas Department of Public Safety Lt. Christopher Olivarez revealed to CNN that the 21 victims were shot from one room at Robb Elementary in Uvalde.
"Just goes to show you the complete evil from this shooter," he said.
The first officers called to the scene could not enter the classroom and were met with bullets as they attempted to break in.

Olivarez said the officers went around breaking windows to evacuate children and staff from other parts of the building.
He said: "It's a small classroom, you can have anywhere from 25 to 30 students in there, plus there were two teachers in there.
"So don't have exact number of how many students were in that classroom, but it could vary.
“It was a classroom setting, a typical classroom setting where you have mass groups of children inside that classroom all together, with nowhere to go.”

NBC News reports officials confirmed that prior to the shooting, the gunman, 18-year-old Salvador Rolando Ramos, wrote in a Facebook message 15 minutes before: “I’m going to shoot an elementary school.”
Ramos also sent another message revealing his plans to shoot his grandmother and then one more message confirming he had done it.
Communications Director at Meta Andy Stone shared on Twitter that the social media giant is cooperating with law enforcement as they continue to investigate.

He wrote: “The messages Gov. Abbott described were private one-to-one text messages that were discovered after the terrible tragedy occurred. We are closely cooperating with law enforcement in their ongoing investigation.”
Ramo’s grandmother, who is alive after the attack, is also being interviewed by law enforcement.
Since the tragedy, calls to enforce stricter gun laws have continued to grow.
Connecticut's Senator Chris Murphy, formerly a representative from a district that included Sandy Hook Elementary School, gave a powerful speech to the Senate floor yesterday (May 25), demanding gun law reform.
He said: "Find a path forward here. Work with us to find a way to pass laws that make this less likely. I understand my Republican colleagues may not agree to everything I support, but there is a common denominator we can find.”

While speaking at the White House, President Joe Biden also put pressure on Congress to change the country’s gun laws.
He said: "I am sick and tired of it. We have to act. Don't tell me we can't have an impact on this carnage."
