Police follow tracks in the snow to make an arrest

Robbers might think twice about committing a crime when there's snow on the ground. Or at least not head right home.

That's the lesson after Joliet police followed footprints from where a pizza delivery man was robbed to a house on the same block and arrested four teens late Tuesday.

Police say two teens waited on a porch for the pizza man and the two others -- one holding a bat -- approached him.

Police Chief Patrick Kerr says the pizza man turned over pizzas, sodas and $200.

Police say an officer followed the tracks to the house and found two pizza boxes, the pizza man's debit card and a baseball bat.
