An entire school district police force in Texas has been suspended for their failed response to the Uvalde school shooting that left 19 children and two teachers dead.
Salvador Ramos, 18, went on a bloody rampage at Robb Elementary School in Uvalde after first shooting his own grandmother at a house on May 24.
Questions have been asked of the police response to the Uvalde shooting, as armed police waited 58 minutes before entering the classroom where the massacre took place.
There has also been outrage at the length of time it took for police to challenge Ramos, who they eventually shot dead.
In a statement on Friday, the Uvalde Consolidated Independent School District wrote: "Recent developments have uncovered additional concerns with department operations.
"As a result of the developments, Lt Miguel Hernandez and Ken Mueller have been placed on administrative leave.
"The District has made the decision to suspend all activities of the Uvalde CISD Police Department for a period of time.
"Officers currently employed will fill other roles in the district. Ken Mueller has elected to retire."
It is not clear how long the department suspension will last.
The school district said it requested additional officers from the Texas Department of Public Safety to provide campus security.
Two officers, Lieutenant Miguel Hernandez and Ken Mueller, were placed on administrative leave.
The news of the suspension comes one day after a Uvalde cop was fired after they were rehired following quitting their post in the fallout of the shooting.
Crimson Elizondo, 45, was among the first cops to arrive at the scene of the shooting.
Elizondo, a former officer with the Texas Department of Public Safety, was caught on bodycam footage outside the building, failing in her attempts to enter.
Elizondo quietly resigned as the investigation was launched into the police response.
She was then hired at the Uvalde Consolidated Independent School District (UCISD).
Her role requires her to protect the survivors of the shooting but her parents immediately recognised her and demanded she was fired.
The school district confirmed on Thursday that she was fired from her role and apologised to the families of the victims.
In the deadliest school shooting since Sandy Hook almost a decade ago, the attacker murdered 19 children and two teachers in a single classroom where cops also put an end to his spree by shooting him dead - bringing the current death toll to 22.
He then fled from the school, which is believed to cater for children aged seven to 10, before crashing into a ditch.
Ramos - who was clad in body armour and posted chilling images of his arsenal before the attack - is thought to have exchanged gunfire with border patrol agents before barricading himself inside the building.
Two heroic teachers, Imra Garcia, 46, and Eva Mireles, 44, laid down their lives protecting the schoolchildren - both were both married with children of their own.
The school - where some years were preparing to break for summer - has become the scene of the deadliest school shooting since Sandy Hook in Newtown, Texas, when 20 children and six staff members were slaughtered.
The Texas Department of Public Safety said Ramos burst into a single fourth-grade classroom and barricaded himself inside before opening fire.
He was then killed in that room by a tactical unit.
