Three teenagers have pleaded not guilty in the bullying of a 15-year-old girl, who later committed suicide.

The pleas were entered Tuesday by the teens' attorneys inside a Massachusetts courtroom.

Prosecutors say Phoebe Prince was the target of bullying for months, which began after a brief relationship with a star football player ended.

The harassment was non-stop occurring at school, on Facebook, and in text messages.

The 15-year-old hanged herself in January.
