What has been less forthcoming are explanations of how a shooter was able to remain in the school for nearly an hour before he was killed by law enforcement.
Investigators are still working to piece together a timeline to explain how an 18-year-old gunman was able to walk up to Robb Elementary School with a rifle, enter without being stopped through an unlocked door, barricade himself inside a classroom and open fire on a class filled with children.
A scene of chaos and confusion began to form outside the school as news of the attack spread on Tuesday.
On father said he asked law enforcement to give him their gear.
“I told one of the officers myself, if they didn’t want to go in there, let me borrow his gun and a vest and I’ll go in there myself to handle it, and they told me no,” the father told CNN. His son survived.
Several videos captured the frantic scene as parents pleaded with officers to go inside or allow them to go in themselves. The video shows officers holding parents behind the yellow tape of a police line, refusing to let them enter as crying and screaming can be heard in the background.
After about an hour, a US Border Patrol tactical team forced its way into the classroom and fatally shot the gunman, Escalon said.
Days after the confrontation, grief-stricken community members are still frustrated about the delay.
“We deserve to know what happened. These parents deserve to know what happened,” Democratic State Sen. Ronald Gutierrez, whose district includes Uvalde, told CNN, adding “I know there was a failure here.”
“At the end of the day, we have to find out for the future, so that this never happens again, what kind of failures happened. And I feel in this situation, standing back was not the thing to do,” he said.
What we know and don’t know about the shooting timeline
After shooting his grandmother in her home, Ramos drove to Robb Elementary, where he crashed his truck in a nearby ditch, Texas Department of Public Safety Sgt. Erick Estrada said. It’s unclear why he crashed.
The shooter fired at two witnesses across the street before walking toward the school and shooting at the building, according to Escalon.
There were no officers outside the school to stop Ramos when he arrived, Escalon said, contradicting earlier information from authorities that said he was “engaged” by a school resource officer before he entered the school.
That earlier information was “not accurate,” Escalon said Thursday. The shooter “walked in unobstructed initially,” he said.
Then, Ramos got into the building through an apparently unlocked door at 11:40 a.m., Escalon said.
The door he entered through is normally locked, “unless you are leaving to go home on the school bus,” former principal Ross McGlothlin told CNN.
Inside the school, the shooter barricaded himself inside two adjoining classrooms and fired more than 25 times, Escalon said.
At 11:44 a.m., law enforcement arrived and entered the school. Three law officers went in the same door the shooter used and four came in through a different entrance, DPS spokesperson Chris Olivarez told CNN. When they went to confront the shooter, he fired at them and they took cover.
Two responding officers received non-life-threatening gunshot wounds, according to Uvalde Police Chief Daniel Rodriguez.
“It is important for our community to know that our officers responded within minutes” alongside school resource officers, he said.
Officers then called for additional tactical teams and resources such as body armor while they worked to evacuate teachers and students, Escalon said. About an hour later, he said, a US border patrol tactical team was able to enter and kill Ramos.
When asked for more details at a news conference about what exactly responding officers were doing in the hour-long period, Escalon declined to provide further information.
Grieving community reckons with aftermath
In the days following Tuesday’s massacre, the residents of Uvalde are still saturated in grief. For some, the devastating news continued to come as community members learned the husband of one of the victims had also died Thursday morning.
Edward Timothy Silva, a second grader who was in the school, told CNN he recalls hiding behind desks in the dark as he heard loud noises in the distance.
“He was asking me does he have to go to school next year,” his mother Amberlynn Diaz said. “And I just don’t want him to be afraid of school. I want him to continue learning and not be scared of going back to school. I want him to have a normal life again.”
