Tragic: Irish teenager Phoebe Prince

A nasty war of words is breaking out over the Phoebe Prince bullying tragedy in South Hadley.

District Attorney Elizabeth D. Scheibel has slammed school boss Gus Sayer who denies that the school should have done more for the 15-year-old who killed herself on January 14.

Superintendent Sayer said school officials only learned of the bullying the week before Phoebe's death and has denied that officials turned away.

However Scheibel says Sayer is wrong.

“The investigation into Phoebe Prince’s death is ongoing. I do not intend to address Superintendent Sayer’s assertions point by point,” Scheibel said in a statement. “I will, however, say that Mr. Sayer does not have access to our investigative materials. Therefore, he can’t have a basis for some of his remarks.”

Scheibel says the bullying had taken place over the three months before Phoebe's death and was well known.

More importantly, she says that the majority of the abuse took place on school grounds during school hours while school officials say it occurred online and through text messaging.

Three of the nine teens accused of bullying Phoebe will be arraigned Tuesday.

Sean Mulveyhill, 17, Kayla Narey, 17, and Austin Renaud, 18, will appear in Hampshire Superior Court in Northampton at 2 p.m. Tuesday.

Scheibel says the teens were a part of a “nearly three month campaign of verbally assaultive behavior and threats of physical harm” toward 15-year-old Phoebe at the South Hadley high school.

Mulveyhill is charged with statutory rape, violation of civil rights resulting in bodily injury, criminal harassment and disturbance of a school assembly.

Narey is charged with one count of violation of civil rights resulting with bodily injury, criminal harassment and disturbance of a school assembly.

Renaud is charged with one count of statutory rape.
