I don't think it has much to do with burning tax money. There is no statute of limitation on murder and I think everyone is aware that he was murdered. It's like hunting war criminals, they never stopped and shouldn't. There's a very good chance that someone involved may still be alive and the body may reveal evidence. Law enforcement should be applauded for not giving up.
I can't understand either Rick , they like to burn the tax money that's for sure , I beleive Dicks dog food theory might be it. One of the other times the feds demo-ed a large horse barn and found nothing, I can guess who paid that bill as well. Then a few years ago that hit man called the ice man told he was responsible , and the last one I can remember was he was put in a car trunk in at a suburban Detroit salvage yard and the car was mashed and recycled ? One can only wonder.
