Watch: Reporter Confronts TX Official on What Law Enforcement Was Doing for 1 Hour During Shooting

Texas authorities are providing new details about the timeline of the shooting in an elementary school in Uvalde.

But an hour gap between when the shooter entered the school and when he was killed is raising questions.

On Thursday, Victor Escalon, a regional director for the Texas Department of Public Safety, told reporters that the 18-year-old suspect entered Robb Elementary School at 11:40 a.m.

Escalon proceeded to recount the steps taken by the shooter as he made his way through the school.

“Officers are there. They receive gunfire. They don’t make entry initially because of the gunfire they are receiving. But we have officers calling for additional resources, everybody that’s in the area: tactical teams, we need equipment, we need specialty equipment, we need body armor, we need precision riflemen, negotiators,” he continued.

Finally, Escalon said, “During this time that they’re making those calls to bring in help to solve this problem and stop it immediately, they’re also evacuating…students, teachers. There’s a lot going on…Approximately an hour later, U.S. Border Patrol tactical teams arrive. They make entry, shoot and kill the suspect.”

However, the mention of that hour between when the shooter entered the school and Border Patrol agents’ arrival raised some questions.

CNN’s Shimon Prokupecz asked, “What were the officers doing between 11:44 and 12:44? You guys have said he was barricaded. Can you explain to us how he was barricaded and why you guys did not breach that door?

“I have taken all your questions into consideration,” Escalon responded.

Prokupecz pressed, “We’ve been given a lot of bad information, so why don’t you clear all of this up and explain to us how it is that your officers were in there for an hour…but yet no one was able to get inside that room?”
