In a follow-up to last week's college campus shooting at Northern Illinois University in DeKalb, we hear from those who knew Steven Kazmierczak, the man who shot and killed five students there. What is the situation on the campus today? What role, if any, did Kazmierczak's drugs for depression play in the shooting spree?
Police say it appears that Kazmierczak took steps ahead of time to thwart an investigation.
