Uvalde Consolidated Independent School District police Chief Pete Arredondo said there also were multiple injuries from a “mass casualty incident” at Robb Elementary in Uvalde. The gunman is believed to have acted alone and is dead, he said.

The suspected shooter is from Uvalde, Abbott said. He was identified as Salvador Ramos, according to officials.

“It’s 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, but that is not yet confirmed according to my most recent report. He shot and killed, horrifically, incomprehensively, fourteen students and killed a teacher,” he said.

The setting of an elementary school called to mind the Sandy Hook shooting in Connecticut in 2012 that left 26 people dead, including 20 children between 6 and 7 years old.

Meanwhile, law enforcement personnel stand outside Robb Elementary School following the shooting.
