Prosecutors rested their case Wednesday in the trial of a Massachusetts teen accused of raping and murdering his high school teacher.
Defense attorneys for 16-year-old Philip Chism had rested their case Tuesday. Closing arguments are expected on Friday.
Chism is accused of raping and killing his Danvers High School math teacher, 24-year-old Colleen Ritzer, in October 2013. He was 14 at the time but is being tried as an adult.
Defense attorneys have argued an insanity defense in the case against him. A psychiatrist testified in court for the defense said Chism suffered from psychosis.
However, on Tuesday, a psychologist for the prosecution said Chism exaggerated his symptoms of mental illness, adding that she didn't witness psychotic behavior from Chism that his defense clamed after the murder.
