The teenager is believed to be responsible for a list that ranked 50 female students — using racial slurs and ratings of body parts — that circulated around the school and on Facebook, police said. The teen is accused of handing out hard copies of the list Jan. 14 at various lunch periods and posting a copy online, according to police.
