Like glg mentioned above, the Brown's Chicken murders were solved back in 2002 after an ex-girlfriend of one of the killers went to the police.

Between the drop in sales after the Palatine incident (which nobody will forget for a long, long time) and KFC, it's really quite amazing that Brown's is still around. Other articles indicate the owner was being pushed to file bankruptcy but managed to hold out and refinance some existing notes to stay in business.

Not a place I visit only because I try to go for healthier food, but maybe I'll treat myself at some point. Always happy to help out a local business -- why else would I fly United?
