New details emerging in the brutal slaying of high school teacher Colleen Ritzer by student Philip Chism. Sources say Chism waited after school in the bathroom where he murdered Ritzer. Law enforcement sources told ABC news Chism can be seen on surveillance footage dragging a recycling bin around campus, the same one he used to move Ritzer’s body. Chism reportedly went to the movies after he committed the crime. He’s currently being held without bail and charged with murder as an adult.
