(CNN) -- Three teens accused in the bullying of a Massachusetts high school student who committed suicide pleaded not guilty to related charges Tuesday.
Sean Mulveyhill, 17, Kayla Narey, 17, and Austin Renaud, 18, were not present at Hampshire Superior Court in Northampton, Massachusetts, and entered their pleas through their lawyers.
Three other teens also have been charged in what a prosecutor described as a months-long campaign of bullying that led to the suicide in January of Phoebe Prince.
