A woman retrieves a sign that blew off the makeshift memorial for teacher Colleen Ritzer outside the high school where she taught in Danvers, Massachusetts October 24, 2013. The Massachusetts teenager who has been charged with murdering a 24-year-old math teacher at his high school used a box cutter to stab the woman, then disposed of her body and went to the movies, local media reported on Thursday. The 14-year-old, Philip Chism, pleaded not guilty on Wednesday to the charge of murdering Colleen Ritzer, whose body was discovered in the woods behind his high school in Danvers, Massachusetts, some 20 miles north of Boston.
