Adriana Kuch, 14, was found dead at her home in Bayville, New Jersey, two days after she was allegedly beaten by a group of students at Central Regional High School in Berkeley Township.
Four unnamed female students were charged over the alleged beating, which was posted online on TikTok. All four were also suspended by the school.
According to Kuch family attorneys, the lawsuit filed this week against the Central Regional Board of Education and others alleges that officials were aware of “a culture of violence at Central Regional High School” and failed to protect her.
The suit also alleges that they and others should have known that students had been assaulted at the school and "were being recorded and posted to various social media sites by other students."
It was filed days before the one-year anniversary of Adriana’s death. She was attacked on 1 February 2023, and was found dead in her home on 3 February.
"Adriana was the light of our lives, and one year after her horrific and needless death, we are still waiting for justice,” her father, Michael Kuch, said in a statement.
In previous public statements, Mr Kuch blamed her suicide on the school’s inaction in dealing with bullying and its failure to file a police complaint.
He told NJ.com that had the school opened an investigation into the attack after it happened, the video of the incident might not have been posted to social media.
The civil suit seeks unspecified damages for allegations that include negligence, defamation and the infliction of emotional distress. It also seeks unspecified punitive damages.
Online court records did not list attorneys for any of the defendants in the case.
In the original video of the gang attack, Adriana could be seen walking down a hallway with her boyfriend when a student launched at her and hit her over the head with a water bottle.
As the freshman fell to the ground and lost consciousness, the student continued to punch her in the head and pull her hair, drawing cheers from a watching crowd.
The footage went viral on social media, with some taunting Adriana in the comments.
As well as criticism from the Kuch family, shortly after the incident more than 200 students staged a walkout from the school to protest its handling of bullying allegations.
District superintendent Triantafillos Parlapanides responded to the criticisms by pushing the blame for Adriana’s suicide onto drugs and her parents’ marriage in a statement to DailyMail.com.
His remarks drew a furious response from Mr Kuch and Adriana’s classmates, and shortly after he resigned suddenly after 14 years in the job.
