The Uvalde school police department has been suspended after a wave of outrage over the hiring of a former state trooper who was part of the hesitant law enforcement response during the May shooting at Robb Elementary School.

Texas Department of Public Safety troopers will instead provide coverage to the school district, district officials announced Friday.

“As a result of recent developments, Lt. Miguel Hernandez and Ken Mueller have been place on administrative leave, and the District has made the decision to suspend all activities of the Uvalde CISD Police Department for a period of time,” a statement from the district said.

Hernandez was acting district police chief. Mueller was director of student services and plans to retire. Officers still employed will fill other roles in the district, officials said.

This decision come just days after a CNN investigation revealed that a former Texas Department of Public Safety trooper Crimson Elizondo — who is under investigation for a delayed response to the Robb Elementary School shooting on May 24 — was hired as a Uvalde school district police officer just months after the shooting that left 19 children and two teachers dead. She was fired less than a day later following a whirlwind of criticism and anger from parents, district officials confirmed Thursday.

CNN reported that Elizondo had responded to the shooting within the first two minutes of the gunman entering the school and was among the 91 DPS officers who waited in the hallway for 77 minutes before confronting the shooter, while children inside the classroom frantically called 911 for help.

Elizondo was recorded on the day of the shooting telling fellow officers “If my son had been in there, I would not have been outside. I promise you that.”

The school district police department issued a statement Thursday, per FOX 29, explaining that Elizondo’s comments led to her firing.

Brett Cross, whose 10-year-old son Uziyah Garcia was among the victims, had been protesting outside the Uvalde school administration building for the past two weeks, demanding accountability.

“We did it!” Cross tweeted.
