Link to the article. This is very dark and terrible and I feel bad for the parents and everybody involved. What do you think triggered the shooter to do this? From what I've read, people say he was very intelligent, had a personality disorder, but seemed happy. I'm sure there are other articles that says other thing out there that I have not read. The reason to find out why he did this is of course to be able to analyze the behaviour and spot people with risk behaviour. Often they give out a lot of signs that something is bothering them, or have an obsession for wheapons etc. But that goes for so many people. Do you think he was a member of sciforums? He seems to "fit the profile". Could this have been prevented and if so how? I hope this thread is not offensive in any way, just thought people needed to talk about it.
