UVALDE, Texas – Former Texas congressman Beto O’Rourke was shouted down as he interrupted a news conference Wednesday in which Gov. Greg Abbott revealed the gunman in a school shooting posted on social media about his intentions minutes before the deadly rampage.  

The attack Tuesday at Robb Elementary School left 19 children and two teachers dead.

The shooter posted on Facebook about 30 minutes before the attack that he was going to shoot his grandmother, then that he had shot the woman, and finally that he was going to shoot up an elementary school, Abbott said.

After Abbott emphasized the need for mental health services and said of the victims’ families, “what they need now more than ever is our love,” O’Rourke, a Texas gubernatorial candidate, approached the stage with what appeared to be admonitions about the need for gun control legislation.

O’Rourke, who was the U.S. Representative for the El Paso area when a gunman killed 23 people during a 2019 mall shooting in that city, was escorted away.

The massacre took place in once fourth-grade classroom and was the state’s deadliest school shooting in modern history and the nation’s third mass shooting within weeks.

Authorities identified the gunman as Salvador Ramos, 18, but revealed no motive. Ramos had hinted of an attack on social media, according to state Sen. Roland Gutierrez, who said he had been briefed by state police. He said the gunman “suggested the kids should watch out” and that he had bought two assault weapons after turning 18.

Horror, death in one classroom

The killer entered the classroom, locked the door and started shooting, Olivarez told CNN. Officers arriving on the scene began breaking windows around the school trying to evacuate children and teachers. Olivarez said a tactical team forced its way into the classroom and faced gunfire but was “able to shoot and kill that suspect.’’

What do we know about the gunman? 

Texas Gov. Greg Abbott Texas mourns another mass shooting

In the last five years, Texas has been the scene of mass shootings that killed more than 85 people. Worshippers during a Sunday sermon, shoppers at a Walmart, students on a high school campus and drivers on a highway have been the targets. The state’s conservative, Republican-controlled government is unlikely to restrict gun access despite the carnage. Last year, gun laws were actually loosened after a gunman at a Walmart in El Paso killed 23 people in a racist 2019 attack that targeted Hispanics.

“I can’t wrap my head around it,” said Democratic state Sen. Roland Gutierrez,  whose district includes Uvalde. “It’s disturbing to me as a policymaker that we have been able to do little other than create greater access to these militarized weapons to just about anyone who would want them.”
