It was a simple question. On November 4, 1967, the Illinois Crime Investigating Commission asked parking company boss Kenneth S. Leonard if he had ever tried to take over the parking service at Marina City. They had other questions, too, about his mob connections, but Leonard on the advice of his attorney was not talking.

This was part of a scandal involving valet parking in the area of Rush Street. Police had noticed numerous violations of city parking regulations. Leonard operated a company called Attendant Service Corporation. One of his sales people was Ross Prio, reportedly a crime syndicate boss on the north side of Chicago.

Leonard was popular with investigators. At various times, he had been checked out by U.S. Department of The Treasury, Illinois Department of Revenue, IRS, FBI, Chicago police, and Illinois Crime Commission.
