Awful news. Cory, to answer your question.....crime is not rare in Chapel Hill (there's a lot, actually, more than you'd think) but homicide is rare.
gsd -- you're right.....I feel like more stuff like this is bound to happen. Religious tension and conflicts is reaching critical mass right now, it seems like.
As for the nutjob murderer......bro, you have this much problem with Muslims, Christians, foreigners, etc etc, and you live IN OR NEAR CHAPEL HILL??? Pretty dumb planning on your part. There's tons of other places in N.C. you could go and not have to "subject yourself" to people you don't like. Idiot.
