The families of about 20 students at Oxford High School in Oxford, Mich., have filed a federal lawsuit to force the Oxford district to make policy changes in response to the deadly shooting there last year.
The shooting, which occurred on November 30, left four teenagers dead and seven others injured, reports NBC News.
The lawsuit does not seek monetary compensation but rather transparency and communication from the school district.
Attorney Scott Weidenfeller says there needs to be a "third-party investigation" and he wants the district "to stop minimizing threats of violence, to communicate clearly with the parents."
Ethan Crumbley, a 15-year-old sophomore, allegedly fired at least a dozen shots before he was taken into custody. He has been charged with murder and other offenses. His parents have been charged with four counts of involuntary manslaughter in connection with their failure to secure the gun Crumbley used in the shooting.
A separate lawsuit has contended that parents had complained about the suspect's social media behavior and said administrators knew he was dangerous before the shooting.
