The family of a New Jersey middle schooler who committed suicide in June is suing the school district for gross negligence, alleging that the school turned a blind eye to the cyber-bullying that their daughter Mallory Grossman faced for months before taking her own life.

The Grossman family announced the lawsuit against the Rockaway Township School District on Tuesday, NBC News reports, and spoke to the press about the relentless harassment that Mallory, 12, faced through text messages and social media. "For months, there were texts, there was Snapchat, there was Instagram," attorney Bruce Nagle said. "For months she was told she's a loser, she has no friends. And finally, she was even told, 'Why don't you kill yourself?'"

Despite filing multiple complaints with Copeland Middle School officials, the family claims that the school district did nothing to prevent the bullying. Diane Grossman, Mallory's mother, said she even alerted the school to the issue on the day before her daughter committed suicide.

"She would bring something to my attention, I would bring it to the school's attention several times, and they dismissed it every time," Dianne Grossman said Tuesday, according to ABC-7. "There was a pattern."

The pattern began in October, Grossman said Tuesday, and involved several girls tormenting Mallory, mostly online. As a result of the "vile and malicious" bullying, Mallory's grades plummeted, and she began suffering from headaches and stomach pain, her mother said. The family had begun the process of moving their daughter to private school, but "unfortunately, she didn't give us a chance to," Grossman added.

The lawsuit may also name the parents of three or four of the girls who allegedly bullied Mallory, reports. On the night before her daughter's death, Diane Grossman also contacted one of the parents of an alleged bully, who "said it was just a big joke and defended her daughter," according to the Grossman.

On Wednesday, Greg McGann, the superintendent of Rockaway Township School District, posted a notice on the district's website, saying that he hadn't seen the lawsuit, and would not be discussing it while the investigation was ongoing.

"The teachers, staff and administrators within the Rockaway Township School Distsrict are, as they have always been, and will continue to be, committed to protecting the rights and safety for al our students," the superintendent added. "As our new school year begins in just over a month, our vigilance on behalf of our children and their quality education in our schools, is our primary focus and concern."

If someone you know exhibits warning signs of suicide: do not leave the person alone; remove any firearms, alcohol, drugs or sharp objects that could be used in a suicide attempt; and call the U.S. National Suicide Prevention Lifeline at 800-273-TALK (8255) or take the person to an emergency room or seek help from a medical or mental health professional.
