Snippers?

Okay so I was on my internet providers home page, and I stumbled upon an article, about a supposed snipper who killed three teens and one wounded. (our deep regreats to there families) The killer was found after a wild man hunt.  What I may ask is why?  Why these kids, why the camo, and why just giving up and not talking?  Call me crazy but I have a bad feeling about this.  Check out the article here
