Salem — Prosecutors and a lawyer for a 15-year-old boy accused of killing his high school math teacher are due in court this week for a pretrial conference.
Philip Chism pleaded not guilty last month to murder, aggravated rape and armed robbery charges in the Oct. 22 death of Colleen Ritzer, a teacher at Danvers High School.
Chism is accused of killing Ritzer in a school bathroom after she asked him to stay after school for extra help. Ritzer’s body was found in woods near the school with her throat slit and a note reading, ‘‘I hate you all.’’
A pretrial hearing is scheduled Thursday in Salem Superior Court. Chism is being held without bail and is not expected to attend the hearing.
Chism had recently moved to Danvers from Tennessee.
