Rezko's former business partner, godson of John Stroger found shot to death
Besides the Las Vegas matter, Jones had been interviewed by federal authorities about a separate, government-related deal highlighted in a Chicago Sun-Times story in Wednesday's editions.
That deal - which involved an annual fee paid to Jones by an investment firm that does business with a state-government pension fund - allowed Jones to be paid hundreds of thousands of dollars annually for a job he did in 2004.
Stephenson said authorities wanted to know if indicted Highland Park businessman Stuart Levine played any role in helping Jones land the deal.
Levine has been indicted along with Wilmette businessman Tony Rezko in a kickback scheme to defraud Illinois taxpayers using fees such as those Jones received.
Jones told the feds Levine played no role in Jones landing the fee, Stephenson said. He added that Jones was not asked about Rezko.
Like Jones, Rezko is close to the Stroger family, and Rezko and Jones have been business partners, records show.
