Smiley face killers may be stalking college men - CNN.com: "ALBANY, New York (CNN) -- At the age of 21, Christopher Jenkins appeared to have everything going for him. The University of Minnesota senior was good-looking, had a near perfect grade-point average and had a future in business.

Then, suddenly, he vanished.

He was last seen celebrating Halloween at a bar in downtown Minneapolis, Minnesota, in 2002. Jenkins' friends said he left about midnight. Four months later, his body was found in the Mississippi River, still wearing his Halloween costume."
