Oxford High School parents Jeffrey and Brandi Franz are seeking more than $100 million in damages in a lawsuit, claiming the deadly shooting at their teenaged daughters’ school was entirely preventable, as reported by CNN. 

The parents filed the suit on behalf of Riley, 17, and Bella, 14, accusing the Oxford Community School district, Superintendent Timothy Throne, Oxford High Principal Steven Wolf and Dean of Students Ryan Moore, two school counselors, two teachers and a staff member of ignoring threatening social media messages posted by 15-year-old suspect Ethan Crumbley.

Bella allegedly witnessed Riley being shot in the neck, an experience that the lawsuit claims has left both girls suffering from post-traumatic stress disorder. 

They also claim Ethan’s concerning behavior, which was reported by two teachers on separate occasions, including hours before the shooting, was not further escalated to the school safety liaison officer. 

“And as a result, by doing the things that they did or didn’t do, they placed the students in much greater danger than they would have been had they done that. The students would have been protected, and that is basically the essence in the federal complaint here,” said family attorney Geoffrey Fieger, per CNN. “These are the types of things that children don’t recover from, not easily, not ever.” 

Ethan is accused of killing four students and injuring six other people, including a teacher, on Nov. 30, with a handgun his parents bought him for Christmas. He faces charges as an adult that include first-degree murder and terrorism and has since entered into what Michigan courts interpret as a not guilty plea. His parents, James and Jennifer Crumbley, have pleaded not guilty to involuntary manslaughter.

Throne and Wolf allegedly told parents and students they were safe at the high school and discouraged them from discussing or spreading Ethan’s posts, according to the Franzes’s lawsuit. Throne declared there was no need for disciplinary action in a video message to the school community on Dec. 2.
