I agree there are similarities here -good finds. I am still on the fence as far as 1 or 2+ killers so I still think that the dismembered victims on LI (with similarities to cases elsewhere) plus the string of strangled males found near them and/or in sump areas are likely related). It looks like I have been focusing on a different area -and using a very inclusive approach (even some cases with convictions) in which I will be admit some may have too many differences, but in an effort to highlight some forgotten cases I'm including them:
