I remember watching the really sad case of Della Brown and Mindy Schloss' murders on one of the forensic documentary shows. I think FBI Files or Criminal Pursuit?

Anyway, I haven't read the book yet, but apparently this journalist lays out a case for why Wade should be connected to other murders. (On top of Della and Mindy, and three more he confessed to so he could get a cushier prison slot.)

I couldn't find a thread on him, hope this is OK.
