Judicial documents revealed that the families of the victims of the massacre that took place at the Uvalde School, Texas, which killed 21 people, filed a lawsuit to demand huge financial compensation.
The lawsuit, filed in federal court in Austin on Tuesday, alleges that officials failed to follow active shooter protocol when they waited more than an hour to confront the attacker inside a fourth-grade classroom.
It is seeking class-action status and compensation for the survivors of the May 24 shooting, for those who suffered psychological or emotional harm as a result of the defendant's conduct and negligence on that date."
Among those suing are school staff and minors' representatives who were present at Robb Elementary School when a gunman stormed the campus, killing 19 children and two teachers in the deadliest school shooting in the United States in nearly a decade.
Two officers were fired for their actions at the scene and others resigned or were placed on leave.
In October, Steve Macro, the head of the Texas Department of Public Safety, acknowledged the officers' mistakes but defended his agency, saying they "didn't let down" Uvalde.
