(CNN) -- Philip Chism, 14, pleaded not guilty
Wednesday to murder, aggravated rape and robbery charges in connection
with the killing of his high school math teacher, Colleen Ritzer.
teenager is accused of killing Ritzer, 24, on October 22 in the girls'
bathroom of Danvers High School with a box cutter he had taken to
In Wednesday's Superior
Court hearing, Chism -- wearing khakis, a blue sweater, a white shirt
and tie -- was ordered held without bail; his next court date was set
for 2 p.m. on January 30. During the 11-minute hearing, he sat quietly,
his hands cuffed in front of him.
According to a police
affidavit unsealed last month, a ninth-grade student told investigators
that Chism became visibly upset when Ritzer spoke after class on the day
of the crime about his home state of Tennessee.
When Ritzer noticed that
Chism was upset, she changed the subject, said the unidentified student,
who described Chism as "talking to himself."
Denise Regan, Chism's public defender, has declined to comment.
The affidavit includes
testimony from witnesses as well as a school video surveillance timeline
showing Chism and Ritzer in the same area of the school during the
teacher's final moments.
In the video, Ritzer
appears to enter a second-floor girls' restroom -- apparently a faculty
restroom was occupied -- and Chism, wearing gloves and red sweatshirt
with the hood pulled over his head, appears to enter the restroom about a
minute later, according to the affidavit.
Shortly after, a female
student enters the bathroom and then quickly walks out, according to the
court papers. She told investigators she saw the back of a person who
appeared to be changing clothes; the person's rear was exposed, with
clothes piled on the floor.
The video shows Chism
leaving the restroom, returning later with a recycling barrel, and again
leaving the restroom pulling the barrel -- this time with a black mask
on his forehead, the court papers say. He pulls the barrel outside the
building and toward the student parking lot. Investigators said the
video shows what appear to be blood stains near the bathroom and on
After Chism was reported
missing by his mother on the evening of October 22, police had his
cellular phone company "ping" the location of his phone. The phone was
found to be in the vicinity of the Hollywood Hits Theater, where
investigators learned the teen had purchased a movie ticket and then
The affidavit said that,
when Chism was spotted by a police officer the next day, he was
carrying a knife; a search of his backpack turned up a bloodstained box
cutter. Asked where the blood came from, Chism allegedly responded: "The
girl." He was also allegedly carrying credit cards and driver's
licenses belonging to Ritzer, as well as a pair of woman's underwear.
The armed robbery indictment alleges that Chism robbed Ritzer of credit cards, an iPhone and her underwear.
Ritzer's body in a wooded area near the school, covered with leaves and
debris in an apparent attempt to conceal it, the court papers said. Her
throat was slit.
The green recycling bin
seen in the surveillance video was found 20 yards from the body.
Clothing and other belongings were scattered near the body, along with
the blood-soaked gloves Chism appeared to have been wearing in the
video. The handwritten "I hate you all" note was folded near her body,
according to the documents.
Investigators used the affidavit to secure a warrant to search Chism's home.
Chism's mother, Diana,
told investigators that she had recently moved to Massachusetts from
Tennessee amid a "stressful divorce" from the teen's father.
Documents filed 12 years
ago in a Tennessee court shed light on a troubled relationship. The
court papers showed that Chism's father agreed during a separation from
his mother to have restricted time with his son, who was then 2, because
of "prior physical and emotional abuse as well as alcohol abuse."
Chism's uncle, Terrence
Chism Blaine, told CNN that the boy's parents are separated and that the
father -- a former military man -- lives in Florida.
On the aggravated rape
and armed robbery indictments, Chism was charged as a youthful offender,
but prosecutors said they would move to join those charges with the
murder case in Superior Court.
