Philip Chism killed his math teacher Colleen Ritzer

SALEM, Mass. — Jury selection has begun in the trial of a Massachusetts teenager accused of raping and killing his math teacher.

Philip Chism was 14 when he was charged in the 2013 death of 24-year-old Colleen Ritzer, a teacher at Danvers High School. He is being tried as an adult.

Jury selection began Wednesday in Essex Superior Court in Salem.

Ritzer’s body was found in woods near the school. Prosecutors say her throat had been slit with a box cutter.

Defense attorneys have said they plan to use a mental health defense but haven’t revealed specifics.

A student in Ritzer’s class said she overheard the teacher asking Chism to stay after school after she saw him drawing instead of taking notes.

Chism had recently moved to Massachusetts from Clarksville, Tennessee.
