In the urban legend I've heard since I was 3 a chainsaw was never used either and leatherface wasnt called so its just so obvios the connection between him and the ******** son. The Ed gien stroy seems alot alike the urban legend but I'm sure the legend came first maybe he heard it and thats where he got his ideas. I also have done lots of research on gien and[a trailer for the movie just came on my tv SO KOOL] I know the whole stroy i'm sure there is a connection i dont beleive in coincedences.
