In the aftermath of the mass shooting event in Uvalde, Texas, Sen. Sue Rezin (R-Morris) expressed grief.

“My words cannot express the utter shock and sorrow I felt when learning about yesterday’s shooting at Robb Elementary School in Uvalde, Texas,” Rezin wrote on Facebook. “I’m absolutely heartbroken for (the) loss of so many innocent young lives to such a senseless act of violence.”

The Texas Tribune has an timeline of what was known as of May 27 and notes that the individual who perpetrated this mass shooting had asked a family member to get him a gun before he turned 18 and she refused. 

The timeline moves to March 1-3, where he sends private messages via social media about buying a gun. He later posted a “10 More Days” note on Instagram, and purchased two AR-15 rifles and ammunition, between May 16 and May 20.

The shooting occurred on May 24.

Salvador Ramos, 18, used his two legally purchased AR-15-style semi-automatic rifles to kill 19 children and two teachers.

“I had an uneasy feeling sometimes, like ‘what are you up to?’” Adriana Reyes, Ramos’ mother, told ABC News’ chief national correspondent Matt Gutman in an interview at her home. “He can be aggressive... If he really got mad.”

ABC News reported on May 31 that the Uvalde School School District and Uvalde police are no longer cooperating in a state probe of the incident. The center of the probe is law enforcement’s response after officers waited nearly an hour before entering the school.

Uvalde authorities confirmed it took an hour after Ramos entered the building before police killed him.

“It’s all over the world,” resident Donald Limon, 64, said to the Texas Tribune of public reaction to how the incident was handled. “Everybody knows, everybody’s saying the same thing: ‘Why were they standing outside?’ ‘Why didn’t they go in?’”

Nineteen children and two teachers died at Robb Elementary School in Uvalde, Texas, on May 24. NBC News profiled each of the victims.
