A 24-year-old Danvers High School teacher was found dead and a 14-year-old faces charges in her death.

Essex District Attorney Jonathan Blodgett said the body of Colleen Ritzer was found last night in a wooded area near Danvers High School. Ritzer, 24, was reported missing Tuesday evening. Investigators found blood in a second-floor bathroom of the school and soon discovered her body in a wooded area near the school.

All public schools in Danvers were closed Wednesday morning because of the homicide investigation.

The academic wing of Danvers High School had been blocked off with crime scene tape. Blodgett said the 14-year-old suspect was in custody and is expected to be arraigned today. He was reported missing Tuesday night but was later found by Topsfield police, the Associated Press reported.

Blodgett did not confirm how Ritzer died.
