CHICAGO (CBS) — A new DePaul College of Law study identifies three Chicago-area communities that have the most instances of prostitution in hotels.

They are: Schiller Park, Schaumburg and Lansing.

“I was personally surprised to find that most of these hotels are very legitimate, name hotels,” said the study’s author, professor Jody Raphael.

“These are not fleabags in any sense of the word.”

Her study says prostitution was found in 41 hotels and motels in the Chicago area.
