Police knew children were alive in the room with Texas gunman

This includes the police narrative of how the gunman entered the building, and what police knew when about the fatalities and injuries in the classroom.

Law enforcement officials originally stated that a teacher had left open the door that 18-year-old gunman Salvador Ramos entered the school through, having propped it open with a rock. The teacher had actually closed the door after seeing Ramos scale the school’s fence.

Though the door was closed, it did not lock, the San Antonio Express-News reports.

Speaking for his client, lawyer Don Flanary said that the unnamed teacher’s story nearly matches up with the timeline set forth by Steve McCraw, director of the Texas Department of Public Safety, but that he wanted to set the story straight that the teacher had not left the door open.

McCraw had said during a Friday press conference that the door "wasn’t supposed to be propped open, it was supposed to be locked. And certainly the teacher that went back for her cellphone propped it open again. So that was an access point that the subject used."

Flanary said though that "she saw the wreck," meaning when the shooter crashed his truck near the school. "She ran back inside to get her phone to report the accident. She came back out while on the phone with 911. The men at the funeral home yelled, 'He has a gun!' She saw him jump the fence, and he had a gun, so she ran back inside."

The teacher had gone outside to carry food from a car to a classroom shortly before the shooting began.

"She kicked the rock away when she went back in. She remembers pulling the door closed while telling 911 that he was shooting. She thought the door would lock because that door is always supposed to be locked," Flannery added.

Flanary noted that the teacher remembered pulling and holding onto the horizontal push bar attached to the door, while she was on the phone with 911.

On Tuesday, DPS spokesman Travis Considine confirmed part of Flanary’s account

"We did verify she closed the door," Considine said. "The door did not lock. We know that much, and now investigators are looking into why it did not lock."

An unnamed source who was not authorized to speak to the media said that investigators are trying to determine whether the lock was not functioning, or if someone had unlocked the door earlier in the day.

During the attack, Ramos killed 19 children, 2 teachers, and injured 17 others. He was inside the building for over an our before Border Patrol tactical officers broke in and fatally shot him.

Video streamed through FaceBook Live on the day of the shooting, obtained by ABC News, revealed that a Border Patrol agents were speaking with a child inside the building who had been shot.

"Are you injured?" The agent asked the child.

"I got shot," the kid responded.

The call contradicts the original claims and actions from the police department. McCraw said on Friday that police waited to enter the building because the incident commander had considered Ramos a "a barricaded subject, and that there was time, and there were no more children at risk," the Daily Mail reported.

During the Friday press conference, McCraw detailed the calls made by children inside the building, including one girl who called 911 three times, updating dispatch on the number of students still alive in the room.

After coming under fire for waiting so long to engage with the gunman, McCraw said that it was "a wrong decision."

"There was no excuse for that," he added.
