Attorneys hand-delivered a $27 billion lawsuit related to the shooting at Robb Elementary to Uvalde officials Wednesday. 

So far, the class-action suit does not involve immediate relatives of the 21 people who died on May 24. Instead, the plaintiffs are mostly parents of children who were on campus during the shooting, away from the classrooms the gunman attacked, KENS5 reports.

The plaintiffs named specific law enforcement officials who responded to the incident, along with DPS head Steve McCraw. They're also suing the school district and former UCISD police chief Pete Arredondo. 

The lawsuit states that surviving children experience nightmares, severe anxiety, emotional changes, anger, separation anxiety and thoughts of suicide. 

Parents reportedly want to see changes with law enforcement so everyone can feel safe. Survivors are also demanding policy changes in the school system as well. 

The lawsuit criticizes the actions of Uvalde CISD, the Texas Department of Public Safety, San Antonio Police Department's SWAT unit, Uvalde's Sheriff's office, and Border Patrol saying they "fundamentally strayed from conducting themselves in conformity with what they knew to be the well-established protocols and standards for responding to an active shooter."

Tuesday one of the parents of a child killed during the shooting filed a separate lawsuit against officers and agencies.
