19 students, 2 adults killed in Texas school shooting

At least 19 students and two adults were killed at an elementary school in the U.S. state of Texas after an 18-year-old gunman opened fire, Texas State Senator Roland Gutierrez said Tuesday.

"I can't imagine what it would mean to send your child off to school in the morning and not have them return. It's devastating," Gutierrez told CNN.

The shooting happened at Robb Elementary School in Uvalde, Texas, about 83 miles (133 kilometers) west of San Antonio.

"He shot and killed horrifically, incomprehensibly 14 students and killed a teacher," said Texas Gov. Greg Abbott at an earlier news conference.

"It is believed that he abandoned his vehicle and entered into the Robb Elementary School in Uvalde with a handgun and he may have also had a rifle," continued Abbott.

The shooter was identified as Salvador Romas from Uvalde and was believed to have been shot and killed by police who exchanged gunfire. Before the carnage at the school, the shooter wounded his grandmother.

"Mr. Romas the shooter…he himself is deceased," said Abbott.

The Uvalde Consolidated Independent School District issued a statement on Twitter immediately after the shooting took place at about noon local time.

"There is an active shooter at Robb Elementary. Law enforcement is on site. Your cooperation is needed at this time by not visiting the campus," said the statement.

"Our hearts keep getting broken. Every time a tragedy like this happens, our hearts break and our broken hearts are nothing compared to the broken hearts of those families," said Vice President Kamala Harris in an address in Washington, D.C.

Following the shooting, President Joe Biden ordered that the U.S. flag be flown at half-staff at the White House and on all public buildings and at all military posts and naval stations.
