BREAKING NEWS!!! 15 Killed, Including 14 Children, in Texas Elementary School Shooting

Fifteen people were killed — 14 students and a teacher — during a shooting Tuesday at an elementary school in Uvalde, Texas, Gov. Greg Abbott announced.

According to Abbott, the shooter, identified as Salvador Romas, is dead. It is believed the shooter, who opened fire at Robb Elementary School, was killed by police.

Police said at a Tuesday press conference they believe the suspect acted alone. The children killed were in the third, fourth and fifth grades, police said.

At 12:17 p.m. CT, the Uvalde Consolidated Independent School District tweeted about the active shooter at the school. Later, police in Uvalde, a small city of about 16,000 residents about 80 miles west of San Antonio, announced on Facebook that the shooter was in custody.

"He shot and killed — horrifically, incomprehensibly — 14 students and killed a teacher. [The shooter], he himself is deceased," Abbott said. "And it is believed that responding officers killed him."

Abbott also said the shooter shot his own grandmother, but did not give an update on her condition.

According to Abbott, the shooter had a handgun and possibly a rifle.

Congressman Tony Gonzales, who represents the area, said in a statement, "I am heartbroken for our South Texas community. It is devastating when our innocent children become the victims of senseless violence. We are devastated."

The Newtown Action Alliance, a gun violence prevention organization launched after the 2012 Sandy Hook Elementary School mass shooting in Connecticut, in which 26 innocent people were killed, issued a statement on Twitter saying, "We are devastated. Our hearts are breaking for Robb Elementary & Uvalde families & community. We are angry. These shootings are preventable but those whose stood with the NRA after Sandy Hook nearly 10 years ago did absolutely nothing to prevent these tragedies. We need change."

White House Press Secretary Karine Jean-Pierre said President Biden will speak later this evening.

"His prayers are with the families impacted by this awful event," Jean-Pierre tweeted.

The mass shooting comes less than two weeks after an alleged white supremacist killed 10 people inside a grocery store in Buffalo, N.Y. Authorities have said the Buffalo shooting was a hate crime in which the suspect targeted Black people.
