BOSTON- A teenager charged with killing his teacher is due in court this week on charges stemming from an assault on a Department of Youth Services worker.
Philip Chism, of Danvers, is scheduled to be arraigned Wednesday in Suffolk County Juvenile Court.
The 15-year-old Chism is charged with murder in the killing of his math teacher, 24-year-old Colleen Ritzer, in October.
He was indicted last month for allegedly assaulting a 29-year-old female staff member at the Metro Youth Services facility in Boston, where he was being held while awaiting trial in Ritzer's death. Chism is charged with attempted murder by strangulation, assault with intent to murder, kidnapping and two counts of assault and battery with a dangerous weapon.
Prosecutors say Chism followed the woman into a bathroom and physically assaulted her.
