According to the investigators at Virginia Tech, Cho may be under the influence of depression drugs which may cause suicidal behavior, psychosis and homicidal ideation. Some people couldn’t help thinking about the Columbine High School rampage happened almost 8 years ago and wondered if antidepressants were involved.
It is not possible that antidepressants are involved on these issues. It is very common story and most attacks are committed by those people under antidepressant medications. I wonder what the FDA would do next.
