Myspace and other online profiles that were registered to Steve Kazmierczak. He actually logged into both a couple of hours prior to the shooting. His myspace blogs are very telling and contain entries made just hours before the shooting. After reading all of his blogs I definitely think it was break-up related and not coincidental it took place on Valentine's day.
