During the shooting on Tuesday, police circled Robb Elementary School in Uvalde, Texas, breaking windows in an effort to evacuate children and staff, Texas Department of Public Safety spokesperson Chris Olivarez told CNN.
Officers eventually breached the classroom and killed the gunman, identified as 18-year-old Salvador Ramos.
Ramos began his rampage by shooting his grandmother at the home where he lived with his grandparents. He then drove to the nearby school where he crashed his car and entered the building wearing tactical gear and carrying a rifle, authorities said.
