The Grossman family may also pursue legal action against the parents of the three or four girls who they say bullied Mallory.
Mallory’s mother, Dianne Grossman, said she spoke to the mother of one of the girls the night before Mallory took her own life.
Some of the cyberbullying against Mallory – at least two of the girls’ Snapchats – took place on school property, Grossman said.
In Mallory’s final days, her parents were trying to move her to a private school, but "unfortunately she didn’t give us a chance to do so," Grossman said.
The mother dismissed the bullying, telling Grossman it was just a "big joke" and that she should not worry about it, Grossman said at the news conference.
