For years, the housing authority in Alexander County in southern Illinois, let their public housing properties deteriorate.  By the time the Federal Department of Housing and Urban Development took over, the buildings were too far gone to repair.  So HUD shut them and left hundreds of families looking for affordable places to live in a market that has little to offer.  Many residents have had to relocate hours away from the places they lived for decades. Molly Parker of The Southern Illinoisan and Pro Publica has the story.
