Mallory Grossman was attending Copeland Middle School when she killed herself in June, according to attorney Bruce Nagel, who said at a news conference the girl's family plans to sue the Rockaway Township School District as well as all administrators who ignored the family's pleas for help.
"For months she was told she was a loser, she had no friends, and finally she was told, 'Why don't you kill yourself?'" he said.
Some of the cyberbullying against Mallory - at least two of the girls' Snapchats - took place on school property, Grossman said.
Nagel said that Mallory's parents, Dianne and Seth Grossman, had been asking the district to address "relentless bullying" of Mallory on Snapchat and through text messages sent to her by other girls in the school.
Grossman said she tried to talk with other kids' parents, but her concerns were dismissed. "We want to end this forever", Nagel says.
Then, on June 14, Mallory took her own life.
Dianne Grossman said she and her husband pleaded with school officials, to no avail.
"There was a pattern, a regular history pattern of who the school district dismissing my concerns", Grossman said.
The mother said her daughter was targeted because she was popular at her school, "an athlete, a quiet child and a good student", and represented what her bullies couldn't be.
Six weeks after her daughter's suicide, Grossman made it clear who she held responsible for her daughters death - the school.
Dianne Grossman and her attorney said Tuesday that the Rockaway Township school district did nothing to protect her daughter, Mallory Grossman, from being bullied for months by a group of girls online, NBC New York reported.
After the bullying began in October of past year, Mallory's parents spoke to her teachers, counselors and school administrators - along with the students' parents - pleading with them to help put an end to the ugliness.
Accusing the institution did not do enough, Nagel said: "They should have taken steps to bring in the children, bring in the parents and get this stopped". The Grossman family is "contemplating" taking action against these parents for allowing the bullying to persist for months, Negal told WPIX. Mallory was a cheerleader and gymnast who family says was well-liked and sociable. She was described as a compassionate, creative young girl who loved nature, the outdoors and "flowers, every color and shape".
She also criticized the fact that the school touted its self-assessed A grade in recent anti-bullying reports, giving itself a score of 74 out of 78 in the most recent self-assessment posted on the district's website. The family also announced a nonprofit to combat cyber-bullying called Mallory's Army.
