Chism has now confessed to the killing, but still denies raping the woman.
Prosecutors allege Philip Chism killed Ritzer in a Danvers High bathroom, put her body into a recycling bin, and dragged it into woods near the school. The 24-year-old Ritzer suffered massive injuries to her neck, prosecutors said. The teen is charged with first-degree murder and aggravated rape.
“I do know that he is capable of snapping. I’ve always felt that way,” said the suspect’s mother, Diana Chism in court on Jan. 9, 2015.
The high school algebra teacher was reported missing the same day her killer was also reported missing, according to authorities.
Police say Chism was found walking on the side of the highway the next day with a box cutter covered with what was reported to be blood.
When police asked the boy whose blood was on the weapon, Chism replied “It’s the girl’s,” Topsfield Officer Neal Hovey testified.
Police say that was when Chism was read his rights and taken under arrest.
According to Officer Joseph DeBernardo, the other officer on the scene, after he read Chism his rights, he asked where the girl was, to which the teen replied, “Buried in the woods.”
DeBernardo said he then asked if the girl could be helped if she was located, and Chism said “No.”
Chism was also allegedly carrying credit cards and driver’s licenses belonging to Ritzer, as well as a pair of woman’s underwear.
Chism, who is being held without bail, is set to appear January 30 in Salem Superior Court for a pre-trial conference.
