Prosecutors frantically look to interview Kelly's associates in connection with their sex trafficking investigation.
Federal prosecutors in the U.S. Attorney's Office for the Northern District of Illinois this week contacted parties closely associated with Kelly. We're told there was a sense of urgency to the calls ... prosecutors wanted to speak to them ASAP.
there are 2 separate U.S. Attorney probes into Kelly -- one by the Eastern District of NY and another by the Southern District. Our sources tell us the Northern District of Illinois' investigation is unrelated to either of those other cases. This appears to be a third and entirely separate
case that Illinois is building against Kelly.
Homeland Security is also looking into possible human trafficking ... so things are really piling on for Kelly.
