I think this one if from the 1970ís it was about a guy who worked at a meat processing plant and accidently kills someone and this leads to more murders which he hides in his apartment and they start stinking. A blind man who lives above him comes to confront and aid him. He begins cutting up the bodies and taking them to work to grind them up. He eats at a dinner every day and they announce to him that they have begun getting their meat from his factory. Thatís all I can remember. Thanks for any help.
