DANVERS, Mass. (AP) — Students return to class this morning at Danvers High School in Massachusetts, just two days after a 14-year-old classmate was charged with the murder of a math teacher.

Police and school officials say there will be extra safety measures to reassure students.

Meanwhile, the family of 24-year-old math teacher Colleen Ritzer is asking for privacy as arrangements are being made "to celebrate Colleen's vibrant life."
