According to authorities,Colleen Ritzer’s body was found in a wooded area behind the high school last night, after blood was found in a school bathroom.
The entire school district shut down today during the investigation.
Danvers is about 20 miles north of Boston and has a population of about 26,000.
It’s not clear at this point if the boy in custody is a student at the high school. Police say he was taken into custody early this morning after he was spotted walking down a street.
Ritzer’s death comes the same week as the death of a teacher who tried to stop a student with a gun at a middle school in Sparks, Nevada.
