The school district police chief who was one of the first officers to arrive at Robb Elementary School in Uvalde, Texas, didn't have a police radio with him when responding to the incident, according to a report.

Uvalde Consolidated Independent School District Police Department Chief Pete Arredondo didn't have a police radio with him when responding to a shooting at the elementary school which left 19 children and two adults dead on May 24, according to a report from the New York Times.

Arredondo's lack of an available police radio could have slowed law enforcement's response to the shooting, according to the report.

Arredondo used a cell phone to call a police landline, informing them of the active shooter situation.

Inside the elementary school, the on-scene commander was convinced that the threat to children had ended and believed they were dealing with a barricaded subject, which was not the case.

During a press conference on Friday, Texas Department of Public Safety Director Steven McCraw said that the on-scene commander at Robb Elementary School during the mass shooting "was convinced at the time that there was no more threat to the children," adding that it was believed that the situation went from an active shooter to a barricaded subject.

"The on-scene commander considered a barricaded subject and that there was time and there were no children at risk. Obviously, you know, based on the information we have, there were children in that classroom that were at risk, and it was, in fact, still an active shooter situation and not a barricaded subject," McCraw said.

"Go in there! Go in there!" one woman yelled at police officers, according to Juan Carranza, 24.

Cazares suggested at one point that a group of people "rush in because the cops aren’t doing anything like they are supposed to. More could have been done. They were unprepared."
