"That could have easily been my daughter and I am angry," South Hadley, Mass., parent Dave Leonard told school officials at a crowded meeting this week.
"You have failed," parent Luke Gelinas added, as the audience applauded. "Until someone admits there's been failure here, complete failure, you have nowhere to go."
But who exactly failed Phoebe Prince? Friends say the Irish immigrant, who moved to South Hadley just last year, had been the recipient of nasty online messages and e-mails. She was found dead in her home two weeks ago.

"Someone told her to go hang herself, and I don't really know who that was," student Jessica Chapdelaine said. "But she was getting bullied by some people, because there were people talking about her and I guess she just didn't like being hated."
Prince's friend Sergio Loubriel said he'll miss "just being around her."
"I didn't want to believe it," he said referring to her death.
Experts say Prince's story is not unique.
Internet safety expert and privacy lawyer Parry Aftab told "Good Morning America" today that this type of bullying amounts to torture for some kids.
"The schoolyard bullies beat you up and then go home," she said. "The cyberbullies beat you up at home, at grandma's house, whereever you're connected to technology."
Aftab said most of the cyberbullies are "mean girls" that target young teenagers through e-mail and social media sites. Signs that cyberbullying is happening can include a child's sudden hesitation to use the technology they had always been enthusiastic about like online gaming, Facebook or e-mail.
She said those being bullied in cyber space need to "stop, block and tell" -- stop reading the insulting messages, block them from your computer and tell someone.
Even in South Hadley, parents say Prince was not the only one being bullied.
"My son has been subjected to physical, emotional and verbal abuse, called an idiot, called a loser," parent Lisa Gustafson said.
Added Abby Peaker, "It was the most horrific thing I've had to watch my child go through, and see her spiral into a downward spiral and lose her spirit."
Police are still investigating Prince's death, which has renewed calls for an statewide anti-bullying law. Currently, 41 states and the District of Columbia have anti-bullying measures and 23 have statutes against cyberbullying. Massachusetts is not one of them.
Police Investigating Suicide of Massachusetts Teenager
Even in death, Prince was bullied. On a memorial page dedicated to the Massachusetts teen who had recently committed suicide, Facebook members left taunting comments that had to be removed.
"It's heart-wrenching," said South Hadley Police Chief David LaBrie. "She had only moved here last summer."
"We are looking at all factors," said LaBrie, who was assisting the Northwest District Attorney's office with an investigation into Prince's death.
LaBrie refused to discuss the details of Prince's suicide out of "respect for the family's privacy.
"It's tremendously emotionally draining on the family and the whole community right now," he told ABCNews.com. "It's such a sad thing."
In a letter to parents, Principal Daniel Smith called Prince "smart, charming, and as is the case with many teenagers, complicated. ... We will never know the specific reasons why she chose to take her life.''
In 2006, Megan Meier killed herself after the mother of a former friend created a fictitious profile to harass the Missouri 13-year-old. Three years earlier, 13-year-old Ryan Patrick Halligan of Vermont hung himself after he'd been bullied online.
Just this week in Lewisville, Texas, a 9-year-old boy hung himself in the nurse's bathroom at his elementary school.
"It's just sad. I can't imagine what would make a 9-year-old boy feel this way," Stephanie Rodriguez, the school's PTA treasurer, told ABC affiliate WFAA television.
This is apparently the second high-profile suicide bullying case in Massachusetts in the past year. In nearby Springfield, 11-year-old Carl Joseph Walker-Hoover hung himself with an extension cord after bullies repeatedly called him gay.
Massachusetts' House Bill 483, sponsored by the Anti-Defamation League of New England, would require schools to have anti-bullying training and procedures in place. It would also require districts to produce an annual report citing incidents for the state legislature and the department of primary and secondary education
"We take no comfort or false security that we grew up with bullying and what's the big deal, we survived," said Derrek Shulman, regional director of the ADL.
"Statistics show in a survey of fourth- and eighth-graders that a large percentage said they had been bullied or were bullied themselves," he told ABCNews.com.
"We know that bullies are more likely to get into trouble with narcotics and law enforcement and that the bullied suffer from self-esteem and there are significant repercussions on being productive members of the community," he said.
The national suicide prevention lifeline number is (800) 273-TALKTALK.
