(NBC News) -- A math teacher was found dead Wednesday in the woods outside her Massachusetts high school, and authorities said they would charge a 14-year-old student with murder.
The body of the teacher, identified as Colleen Ritzer, 24, was found just after midnight in the woods near Danvers High School, about a half-hour outside Boston. Blood was found in a bathroom at the school, authorities said.
Authorities said their murder investigation was connected to their search for a missing 14-year-old boy the day before, but they did not explicitly say that he was the juvenile charged in the killing.
They said the 14-year-old would be arraigned later Wednesday.
Jonathan Blodgett, the Essex County district attorney, told reporters that it was a "terrible tragedy."
"She was a very, very respected, loved teacher," he said.
Public schools in Danvers were closed for the day.
