The suspect also allegedly shot his grandmother before entering the school and again opening fire, Abbott said. He did not say anything further about her condition.

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.

“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.”

Two responding police officers were among those injured, Abbott said. They are expected to survive, he said.

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 any information.

Earlier, the Uvalde Consolidated Independent School District had said a shooter was located at Robb Elementary School and asked people to stay away from the area.

“There is an active shooter at Robb Elementary,” the school district said on Twitter. “Law enforcement is on site. Your cooperation is needed at this time by not visiting the campus. As soon as more information is gathered it will be shared.”

A school official initially told ABC News that the shooting took place off campus, and that Robb Elementary School was under lockdown.

The shooting occurred shortly after 11:30 a.m. local time, police said.

The school, which has students in the second, third and fourth grades, informed parents shortly after 2 p.m. that students had been transported to the Sgt. Willie Deleon Civic Center, the reunification site, and could be picked up.

Parent Ryan Ramirez told San Antonio ABC affiliate KSAT he had gone to the civic center and the elementary school trying to find his fourth grade daughter in the wake of the shooting.

“[I’m] just confused and worried. I’m trying to find out where my baby’s at,” he told the station.
