The violent act shook a nation still reeling from a mass shooting just 10 days ago. Parents in Uvalde, Texas, waited late into Tuesday night at a civic center to learn whether their children had survived, some having given DNA to help authorities identify victims, they told CNN.

Now, the city about 90 miles west of San Antonio and just east of the US-Mexican border finds itself on the long list of American communities devastated by mass shootings.

LIVE UPDATES: Deadly shooting at Texas elementary school

The 18-year-old gunman, who was killed by law enforcement, is believed to have shot his grandmother before driving to Robb Elementary to carry out to attack, according to the Texas Department of Public Safety. She was at a hospital in critical condition Tuesday evening.

The shooter crashed his vehicle near the school, then got out with a rifle and a backpack, DPS spokesperson Sgt. Erick Estrada said. As he tried to enter the school, the gunman was engaged by school district police officers but got into the building and opened fire, Estrada told CNN.

So far, two 10-year-olds and a fourth-grade teacher have been identified publicly by relatives as among the dead.

Tuesday’s massacre is the second-deadliest school shooting since 2012, when 26 children and adults were killed at Sandy Hook Elementary School. It is at least the 30th shooting at a K-12 school in 2022, according to a CNN tally.
