On Thursday, a grand jury in Essex County, Massachusetts indicted 14-year-old Philip Chism on charges first-degree murder, aggravated rape and armed robbery. Last month, Chism allegedly raped and murdered Colleen Ritzer, his math teacher, in the second floor bathroom of Danvers High School before dragging her body into nearby woods.

“The indictments returned today detail horrific and unspeakable acts,” Essex District Attorney Jonathan Blodgett said in a statement, according to the Boston Globe. “This is the first step in a long process to secure justice for Ms. Ritzer and her family.”

Chism was indicted as an adult for the murder charge and as a juvenile on the aggravated rape and armed robbery charges.
