SALEM, Mass. (MyFoxBoston.com) -- Jurors in the murder trial of a Danvers teen went to several important sites in the case Wednesday.
Philip Chism is accused of raping and killing his math teacher, Colleen Ritzer, two years ago.
Before the jurors left the courtroom, testimony continued from the defense team who argued that Chism was not in a normal mental state at the time of the murder.
Dr. Anthony Jackson testified that he diagnosed Chism in October as suffering from a depression and a transient psychotic disorder, triggered by the trial.
In the afternoon, jurors boarded a bus to view some of the scenes connected to the case. They went to Danvers High School and the woods near the school where Ritzer was buried. Jurors also saw the movie theater where Chism bought a ticket with Ritzer's credit card, and Topsfield, where Chism was found.
Chism did not attend the jury view.

The tour came after a day of testimony, when the defense called its own witnesses to the stand. During Tuesday's testimony, a friend of Chism from Danvers High School described what Chism was like in the days before Ritzer's murder. The friend said Chism, usually "very excited" and "very outgoing," suddenly "got quiet and changed completely."
Chism's grandfather also testified Tuesday about a family history of mental illness. Chism's lawyers are expected to use the insanity defense and claim the teen was insane during the rape and murder.
Testimony resumes Friday morning.
