I know it wasn't any Texas Chainsaw movies...

This movie involved some unseen killer for the most part who used mind control to kill. and one was turning the meat grinder on when the guy stepped back into it... the other being the newsman smashed by a concrete block that was hanging from a crane ontop of a building. I guess it may be unrelated to the old lady being hung as mentioned above... but as I said I havent seen these movies since i was like a near baby. Why my parents brought me to these were unreal. But they were 19 and 20 when I was born
