Those lakes at Kickapoo would be very good for hiding a body. It’s an old surface pit coal mine. After it was mined out, it was eventually turned into a state park, @nd they flooded the pits, turning them into deep lakes. Back in the early 2000s, a UIUC student who was from a nearby small town left a party and drove through Kickapoo on his way home. He went missing. Turns out he had driven off the road and had went into one of the lakes. They searched there but didn’t find anything for ten years. One day they were trying out a new kind of sonar and stumbled on his vehicle. The new sonar was able to image it. It just so happened to be a lake they had searched ten years before but had been unable to pick anything up when they searched it the first time.
