Bump.Will do. I think there is a movie on the subject on Netflix if I'm not mistaken.... I have read a theory that this murder was committed by a "travelling serial killer" who was also the New Orleans axe man and I think maybe the Cleveland Torso Killer. Again, I have kinda stepped away from this stuff for the last few months so my memory is a bit rusty.
The title of the book you posted makes me think the author leans towards that theory.
I read the book, & they definitely make a lot of interesting points. A whole lot of similar stuff happens in a series of murders all across the country. Seems like they may have solved the case. Well worth reading, imo.
