At least 19 children and two teachers are dead after a shooting at Robb Elementary School in Uvalde, Texas, on Tuesday, according to the Texas Department of Public Safety.

 

The 18-year-old suspect, a student at Uvalde High School, is also dead, Gov. Greg Abbott said.

 

Abbott said the suspect "shot and killed horrifically and incomprehensibly" more than a dozen students and a teacher.

 

The suspect also allegedly shot and killed his grandmother at a separate scene before entering the school and again opening fire. He then crashed his car outside the elementary school, according to multiple law enforcement officials.

The shooter was identified by law enforcement sources and the governor as Salvador Ramos.

Authorities have recovered an AR-15-style rifle and numerous magazines, multiple law enforcement sources told ABC News.

The suspect, who was wearing body armor, was immediately engaged outside the building as he approached the school by a Uvalde Independent School District police officer, who was shot by the suspect, the sources said.

The students shot were mainly third- and fourth-graders, and one teacher, according to the sources.

U.S. Border Patrol Agents responded to a law enforcement request for assistance, and Uvalde ISD officers and Border Patrol Tactical Unit agents traded fire with the suspect inside the building.

 

Two responding police officers were among those injured, Abbott said. They are expected to survive, he said. One of the Border Patrol agents sustained injuries while trying to protect students and is at the hospital recovering, Del Rio Sector Chief Jason D. Owens told ABC News.

 

"When parents drop their kids off at school, they have every expectation to know that they're going to be able to pick their child up when that school day ends. And there are families who are in mourning right now," Abbott said. "The state of Texas is in mourning with them for the reality that these parents are not going to be able to pick up their children."

 

Uvalde Memorial Hospital had said 15 students were being treated in the hospital's emergency department in the wake of the incident. Two patients were transferred to San Antonio for treatment, while a third was pending transfer, the hospital said. A 45-year-old was also hospitalized after getting grazed by a bullet, the hospital said.

 

University Health in San Antonio said it had two patients from the shooting incident -- a 66-year-old woman and a 10-year-old girl -- both in critical condition.

Two adult victims of the shooting, both in critical condition, are also being treated at Brooke Army Medical Center in San Antonio, according to an Army official.

 

A number of the shooting victims are children of Customs and Border Patrol agents, law enforcement sources told ABC News.

Uvalde Mayor Don McLaughlin did not confirm casualties, but told ABC News in a text message that "this is a very bad situation." He said the office is trying to contact parents before releasing
