Two of the six teenagers charged with bullying a Massachusetts high school freshman so relentlessly that she committed suicide have been sentenced to a year of probation.

Sean Mulveyhill pleaded guilty to criminal harassment Wednesday in Franklin-Hampshire Juvenile Court.

Kayla Narey admitted to sufficient facts to the same charge, acknowledging the state could win conviction at trial.

Both 18-year-olds were ordered to do 100 hours of community service to help at-risk children, complete their high school education and were barred from profiting from their involvement in the Phoebe Prince case.

Prince, who moved to South Hadley from Ireland, hanged herself in January 2010 in her family's apartment about 100 miles west of Boston. Prosecutors say the 15-year-old had been relentlessly bullied at school.
