That number came up on my phone also but I didn't answer.When I tried to call it back it said it was a none working number at the Cook county court house in Skokie.Did you speak to any one there?
The number does belong to a court house in skokie. However, there is a gentleman by the name of Larry/Johnny Gill who tries to recruit people to go into market reseach studies on his behalf and for a cut of the action he will give you the answers to get in.
