Which episode was with the student who kills with a crystal necklace
I have been trying to track down the episode where this girl has a crystal on a chain necklace and she's in the class and she looks through the crystal and the teacher suddenly begins choking and he pulls out cotton from his mouth and keeps pulling and choking until he dies. I was under 10 years old and it's stuck with me until my current age of 32. If anyone can help I'd appreciate it.
