AUSTIN, Texas (WTVO) — A Texas lawmaker revealed in an emotional hearing this week that the Uvalde school shooter — who killed 19 children and 2 teachers — wrote “LOL” on a whiteboard in his victim’s blood.

Rep. Joe Moody (D-El Paso) made the revelation during a hearing with the victim’s families, eliciting gasps and sobs from family members, according to NBC News.

“The attacker scooped up the blood of his victims and smeared it into his disgusting message,” Moody said. “What he wrote in innocent blood next to that was the phrase ‘LOL’.”

The hearing to raise the purchase age for semiautomatic rifles adjourned — shortly after 3 a.m. Wednesday — without a vote.

The result was the end, in the middle of the night, of what may wind up as the only debate in the Texas Capitol this year over a raft of stricter gun proposals filed following the shooting last May.

Other than the late-night hearing, Republican leaders in Texas have not announced any other intention to consider or vote on proposed gun measures before the session ends next month.

As the drumbeat of mass shootings marches on in the U.S., the emotional hearing underlined mounting frustration over gun violence. Gun supporters also stayed late, including a National Rifle Association lobbyist and a man who legally wore a holstered handgun, as well as others who offered sympathies to Uvalde families before urging lawmakers to reject what they called an infringement of their rights.

The hearing went over the grim scene investigators found in the fourth-grade classroom at Robb Elementary after police finally confronted the gunman after 77 minutes, including descriptions that Uvalde families had not previously heard. Many in the room cried.

The string of recent mass shootings has reenergized gun control advocates nationwide, but in Texas, their prospects remain bleak. Republican Gov. Greg Abbott has waved aside talk of raising the age to purchase AR-15-like rifles as unconstitutional and earlier this year made no mention of Uvalde while laying out the priorities of his third term.

The office of Republican state Rep. Ryan Guillen, chairman of the House Select Community Safety Committee, did not immediately respond to a message Wednesday about whether he intends to hold a vote on the gun control bills.

A shooting that killed four young people at a Sweet Sixteen birthday party in Alabama last weekend was the 16th mass killing of the year in the United States. A 17th took place in Maine on Tuesday. A total of 88 people have died in the killings so far in 2023.

A mass killing is defined as when four or more people were slain, other than the perpetrator, according to a database maintained by The Associated Press and USA Today in partnership with Northeastern University.

Before the Kentucky shooting, a gunman in Nashville, Tennessee, last month killed three children and three adults at a private elementary school. Republican Gov. Bill Lee responded by signing an executive order strengthening background checks for gun purchases.

On Wednesday, Washington state’s Democratic-controlled Legislature passed a bill to ban dozens of types of semiautomatic rifles, with Gov. Jay Inslee expected to sign it into law. In Colorado, lawmakers debated a slew of aggressive gun control bills, though a sweeping ban on semiautomatic firearms faced much stiffer odds.

Mata-Rubio is among a group of several Uvalde parents who have been outspoken in their demands for tougher gun laws since the shooting. Before urging the committee to vote to raise the purchase age, she shared the alternative scenarios she still asks herself: What if Lexi had stayed home that week with a stomach bug? What if she had picked her up from school early that day?

She scolded lawmakers for making her wait more than 12 hours at the Capitol to testify. “Did you think we would go home?” she said.

For years in Texas, Republicans have waved aside efforts to tighten gun laws after mass shootings, and even expanded gun rights after the 2019 racist attack on a Walmart in El Paso. Rather than have debates on gun bills this session, Republicans have instead pushed forward proposals to increase mental health services and increase school security.

“Tess didn’t have a choice in life and death,” said Veronica Mata, referring to her 10-year-old daughter who was killed in the Uvalde classroom. “But you as lawmakers have a choice in what her life will be remembered for.”
