The Police Are On The Lookout For Kenny From "South Park"

Or someone who looks very, very much like Kenny. And also seems to be a bastard.

From WTAE Pittsburgh:

The man is described as white, 30 to 35 years old, about 5 feet 9 inches tall and 155 pounds. Police said he wore a gray hooded sweatshirt with the drawstrings pulled closed around his face, blue denim pants and red and white sneakers.

Close enough.
