Teen stayed after final bell with Danvers High School teacher before killing her, buying Wendy's meal with her credit card

Philip Chism, 14, stayed behind when his Algebra 1 class was dismissed for the day after his teacher, Colleen Ritzer, 24, asked him for time to prepare for a test on Tuesday. The teen was later caught on surveillance video donning white gloves and following the teacher to a second-floor bathroom, where he allegedly killed her.

Colleen Ritzer, 24 (pictured), had asked Philip Chism to stay after class to help him prepare for a test, students said.

A 14-year-old boy was with his Massachusetts math teacher for as long as an hour after school before he allegedly killed her — and he changed his blood-stained clothes before going to a movie and buying a Wendy's meal with her credit card, local reports say.
