"She has been receiving significant harassment over the Internet and in other ways," he said. "My client and her family are very concerned for their overall well-being."
Phoebe came to the United States from Ireland in the fall of 2009. In her brief time in the country, authorities said, students at South Hadley High School relentlessly tormented her at school, via text message and through the social networking site, Facebook.
A freshman, Phoebe was reportedly harassed by older girls who resented her dating an older football player. The relationship ended weeks before the suicide, but the bullying allegedly continued.
Her death shook the town of South Hadley and prompted the Massachusetts legislature to pass a law introducing an anti-bullying curriculum in the state's public schools. Studies show that between 15 and 25 percent of U.S. students are bullied with some frequency, while 15 to 20 percent report that they bully others with some frequency, according to statistics cited by the U.S. Department of Health and Human Services.
Brouillard said his daughter also experiences a certain amount of guilt about what happened to Phoebe. She wishes she could have done more to stop the bullying, he said.
He said he had gone to the administration and "begged them for help and begged them to remove these kids from school."
The incident also has unleashed outrage about the lack of charges against adults at the school, although administrators were apparently aware of the behavior.
"The investigation revealed relentless activity directed toward Phoebe, designed to humiliate her and to make it impossible for her to remain at school," prosecutor Scheibel said. "The bullying, for her, became intolerable.
"Nevertheless, the actions -- or inactions -- of some adults at the school are troublesome," she said.
Six of the teens will be indicted this week on charges connected to Phoebe's suicide. Three of the indicted students are girls, charged with violating Phoebe's civil rights, criminal harassment and disturbing a school assembly.
Of the six indicted students, three are still students at the school and three were expelled in February.
Sayer, the school superintendent, had no comment on the growing calls for his resignation. But many people hope the charges and the implementation of an anti-bullying task force will make South Hadley the poster town for change.
"We are the focus now," parent Brouillard said, "and we should be the ones to have the solution at hand and offer it to other communities."
