According to the New York Times, several Uvalde police officers, including the school district police chief, became aware that there were injured people inside the school and that they needed to get them to the hospital.
It's not clear when Uvalde Consolidated Independent School District Chief Pete Arredondo learned of injuries, but a man believed to be him said "we think there are some injuries in there" a few minutes before authorities took out the shooter.
The officer who told other officers his wife had been shot called to say she had been shot.
A team of Border Patrol agents shot and killed the shooter after he fired on the classrooms.
According to documents reviewed by the Times, Arredondo held off on ordering officers to break into the shooter's location because he was concerned about the safety of the officers.
The "hellfire" device was found in one of the classrooms, but it doesn't seem to have been used.
It's not clear if the agents who killed the shooter were aware of Arredondo's order to enter the classrooms.
According to a transcript of body camera footage reviewed by the Times, Arredondo said, "People are going to ask why we're taking so long."
Arredondo tried to talk to the shooter through closed classroom doors after learning of his name.
The police response to the Uvalde shooting is being reviewed by the Justice Department. The narrative of a swift and heroic response that figures like Gov. Greg Abbott trumpeted was shaped by the differing accounts of the police. A student in one of the classrooms begged the police to intervene before the shooter was killed.
Uvalde police were aware of injuries inside and were waiting to confront the gunman.
The student led the police on a chase as they waited for tactical units to arrive on the scene.
The police response to the Texas school shooting will be reviewed by the Department of Justice.
Here's everything that turned out to be false.
