Phoebe Prince's father speaks out for the first time on Dateline NBC

SOUTH HADLEY, Mass. (WWLP) - On Sunday, Jeremy Prince spoke out to Dateline NBC in his first TV interview since the death of his 15-year-old daughter Phoebe.

It was a story that shocked the nation, a story that 22News broke first in January of 2010, when South Hadley High School student Phoebe Prince took her own life after relentless bullying.

22News reports were featured on NBC's Dateline Sunday night during a special episode where Phoebe's father Jeremy broke his silence in an exclusive interview.

He revealed that Phoebe's younger sister actually tried to save Phoebe but it was too late. "She told me that she had tried to undo the knots around Phoebe's neck and couldn't. As a father, to hear that news, what races through your mind immediately? I think natural defense mechanisms in the mind let you take it slowly bit by bit and realize the full horror of it."

Also featured was former District Attorney Elizabeth Scheibel, who spoke about charging the teens who bullied Prince.

One of teens, Sharon Chanon Velazquez, was asked by Dateline what she would say to Phoebe if she were alive today. Her answer: she would have tried to help if she knew what Phoebe was going through.
