San Diego teen commits suicide after bullying over embarrassing video
This is an old video, but I saw it for the first time today. I'd say that this is a case that actually qualifies as cyberbullying. As for the claim that staff at the high school should have known about what was going on I'd have to completely disagree. Teens don't tend to share these types of things with adults since they know that adults will act on this kind of thing and "ruin all the fun" and so it's not at all surprising that staff wouldn't be aware of this bullying campaign or even of the video.
